Trek alpha sizing for MTB – what is it?

The old-school approach of measuring the frame size of Trek bikes is a thing of the past. With newer inventions and modern bike geometry, alpha sizing is used in place of numeric sizing on Trek mountain bikes.

Why is alpha sizing important?

1. Easier approach

Instead of using size numbers like 19.5, the sizes can be classified into S, M, ML, L, XL, and XXL. So, someone with a 17.5 size can go for the medium and a 19.5 is a large size. You don’t have to keep a tab on numbers; instead, the alphabet makes it easier.

2. Measurement based on reach

In earlier times the frame size measurement of Trek bikes was solely based on seat tube length. Things have changed, and modern mountain bike geometry focuses more on reach as of now. Hence, alpha sizing measures what matters and is a more simplified way of measuring bike size.

Trek sizing – virtual vs actual

This can puzzle you a bit as they both are somewhat similar yet there is a subtle difference. Actual size can be termed as the overall length of the seat tube from the center of the bottom bracket to the center of the top tube intersection with the centerline of the seat tube.

On the other hand, virtual sizing is the overall length of the seat tube ranging from the center of the bottom bracket to the mid-point of the imaginary horizontal top tube in which it connects with the seat tube.

If I had to give you an example, a bike might have a virtual size of 18.5 and an actual size of 17.5. This means that the bike size feels like 18.5, but in actual sense, the frame size is 17.5. It doesn’t make much of a difference as it is there only to let you know what it is (actual size) and what it looks like in size (virtual size).

People also ask

Trek 17.5 frame size – what does it mean.

A 17.5 frame size is considered an M size (Medium) in terms of alpha sizing. Any individual who is 161-172 cm or a height of 5’3.4”-5’7.7” . If you are within this height range, going for a medium size shall be the right choice.

Trek medium frame size is for what height?

A medium size frame size (17.5) is ideal for a person with a height between 5’3.4”-5’7.7 ”. In centimeters, it is ideal for those around 161 to 172 cm in height.

Trek 24-inch bike is for what age?

When it comes to children, their bikes are measured in terms of wheel size instead of the standard frame size. These kid’s bikes have a size range between 12-26 inches, depending upon the height of the kid.

As far as a 24-inch wheel size is concerned, any kid between the ages of 8-11 can go for a fun ride with it. Some of the popular 24-inch bike models are Trek Roscoe 25, Wahoo 24, Trek Precaliber 24 , etc.

Trek 26-inch bike is for what height?

A 26-inch wheel-size bike is for kids with a height of 4’9”-5’3” (146-160 cm) . Wahoo 26 is a prime example of a bike in this category.

Trek 20-inch bike is for what age?

Trek 20-inch bikes are for children between 5 to 8 years of age. Additionally, if they are within the height of 3’9”-4’6” , it should be suitable for them.

Are Trek bikes good?

Trek bikes are considered to be extremely good and solid in build. It is known to be the number 1 performance bike brand all over the globe. Having its humble beginning in the year 1976 in Waterloo, Wisconsin, it has turned into the largest bicycle manufacturer all over the world. With an array of bikes ranging from, mountain, road, electric, and kids bikes, there is a lot to choose from a mammoth list.

How much is a used Trek bike worth?

It depends on a lot of factors in terms of how old the bike is, the year of production, which model, and a lot more. However, it can be within $1000-10,000 (depending on the model and other factors) .

Where are Trek bikes made?

The majority of their bikes are manufactured in Taiwan, China, Netherlands, and Germany too.

Why are Trek bikes so expensive?

Usually, the bike brand prefers top-tier components, suspensions, and frames that are ahead of its competitors. This results in additional costs that can be seen in the price tag and also many top-end Trek bikes are custom-made with less production, leading to being more expensive.

Trek bikes are a class apart in many ways with a range of bikes on offer for its fans across the world. Choosing the right size for you can be tricky, but this is where the Trek frame size chart comes to the rescue.

Trek as a bicycle brand might be on the costly side, but they punch above its weight to provide top-class bikes for the masses. I am always someone who roots for quality, and Trek provides what I need.

One comment

Thanks for your informative post. I really like the Trek alpha sizing for MTB because Trek frame sizes use alpha sizing rather than the usual inches or centimeters (cm), and they usually have a certain range of measurements.

• Speed Concept
• Supercaliber

These charts are based upon official Trek website sizing guide for hybrid & city, MTB and road bicycles. Take the charts below as a general guide and check the sizing calculator on the Trek's website for official results.

The Trek bike size chart, taking into account both height and inseam measurements, offers cyclists a comprehensive guide to selecting the perfect bike size for their body proportions. By considering both of these factors, riders can ensure an optimal fit and maximize their comfort and performance on the bike. Height and inseam helps determine the frame size. This chart enables cyclists to find the ideal frame size, for a comfortable riding position. With the Trek bike size chart by height and inseam chart, cyclists can confidently choose a bike that suits their body measurements and enhances their cycling experience.

Most important difference in mtb frames is the frame full suspension or hardtail. Trek offers bikes from both categories and have even more mtb bike types to offer.

Trek Road Bike Sizing

Trek road bicycles are being made in four different categories, depending on the riders needs. Aero road bikes have excellent aerodynamics and they are the choice for riders who are looking for speed and performance. Lightweight road bikes are excellent climbers and all-around bicycles. Endurance road bikes are built for those riders who spend a lot of time in the saddle, their intended use is to make riders as much as comfortable as possible during the long hours of riding. Gravel road bikes are for use on gravel and dirt roads.

Hybrid, as name states, brings a mixture of a road bike and mountain bike. They tend to have narrower tires than mountain bike and usually they have a front suspension (but sometimes comes with rigid fork too). Hybrid frames falls into the specific category between road and mtb bikes. They never come with drop bar, which differs them from road bicycles. They are ok choice for commuting and excellent one for casual fitness riders.

City bikes, as their name say, are intended for urban use on paved, asphalted roads. Main use is for transport and not for recreational riding.

2023 Trek Emonda Size Charts and Guide

In this article, our road bike specialist Bernard Lu guides you on how to find your ideal Trek Emonda size.

This guide provides a detailed sizing chart to help you find the correct Trek Emonda size.

The current model has an H1.5 fit, which Trek claims is the optimal race position for racers . The aggressive geometry places you in a lower and more stretched position than the H2 fit, found on the Emonda ALR.

According to Trek, they introduced a smaller frame (size 47) to cater to a broader range of riders, regardless of gender, body type, riding style, or ability since 2020. The Trek Emonda is now available in eight frame sizes for cyclists from 5’0″ to 6’5″ (152 to 195cm) tall.

Other factors to consider beyond height

Here are important things to consider from my experience working at the bike shop, helping hundreds of customers get their right bike size.

Sizing is different across brands

It’s important to understand that bike sizing isn’t universal across brands. While Trek labels its road bikes with numbers like 47, 50, 52, 54, 56, 58, 60, and 62, these might differ compared to brands like Cervelo or Specialized. 

Always ensure you’re comparing like-for-like when considering sizes across different brands.

Understand the frame’s stack and reach measurements 

Two critical measurements come into play; Stack and Reach to truly compare like-for-like between brands.

If you have a bike that fits you well and is comfortable, use that as a reference point. Find out its Stack and Reach measurements and compare them against the Trek Emonda’s. Pick the closest size.

• Stack is the vertical distance from the bottom bracket to the top of the head tube. Stack height influences how high your handlebars will be relative to your saddle. A higher stack leads to a more upright riding position, which can be more comfortable, especially for longer rides, older riders, and those with less flexibility on the lower back.
• Reach is the horizontal distance from the bottom bracket to the center of the head tube. It determines how stretched or compact your riding position will be. A longer reach results in a more stretched-out, aggressive riding posture, while a shorter reach promotes a more upright position.

The Stack and Reach measurements are on the frame geometry chart below.

Inseam is another key measurement

Your inseam plays a pivotal role in determining the right bike size. Here’s a step-by-step guide to measuring it accurately.

• Stand barefoot with your back against a wall, feet 6 to 8” apart.
• Place a book spine upwards between your legs, ensuring it’s snug against your crotch.
• Step away, keeping the book in position.
• Measure the distance from the floor to the top of the book spine.

For a visual guide, here’s a video demonstrating the process.

In-between sizes? Here’s what to do

Compared to road bike brands , the Trek Emonda sizing chart is relatively easy to understand. Nevertheless, there will be some cyclists that fall precisely on the upper end of the smaller size and lower end of the larger size.

If that’s you, there are many things to consider, such as your legs-to-torso proportions and the final look of the bike, taking into consideration the number of spacers, stem length, and the amount of exposed seatpost.

Generally, I’d recommend sizing down for most cyclists.

Here’s why. 

It’s easier to make a smaller frame bigger than vice versa. The smaller frame has more room to extend reach, and increase stack. However, there is a limit to these corrective measures to avoid having too many spacers (30mm+) or too much exposed seatpost, which makes the bike look out of proportion.

The smaller frame is also stiffer, more maneuverable, and marginally lighter. If set up right, it’ll have more exposed seatpost, leading to more comfort due to increased seatpost flex.

If you have a normal legs-to-torso proportion, opting for the smaller size would be a better choice.

• If you have longer legs with a shorter torso , consider sizing up to avoid having too much exposed seatpost.
• If you have short legs with a longer torso , consider sizing down and using a longer stem to extend reach.

Try before you buy

Visit your local Trek dealer to test different sizes to get a feel for what suits you best. Most large and reputable Trek dealers can provide a test ride if they have the bike in your size in their demo fleet.

Complete Bike Frame Size Chart For All Bikes ?

Every buyer wants a bike that fits, and therefore consulting the correct bike frame size chart is critical.

If the frame is too big or too small, the chances are that you’ll strain. That’s when you start complaining of backache and knee pain, and that’s not all.

You’ll also have a low-performing bike, and that sucks away the joy of cycling. So, to avoid all that, you must pick the frame size correctly.

Note that bike frames vary among different bike types.

For example, the sizing guides for road bikes and mountain bikes are different. The same goes for kids’ cycles and adults’ bicycles.

So that you can understand my drive, I’ll offer you the ultimate sizing guide (plus charts).

Bike Frame Size Chart: Your 3 Options!

Essentially, there are three methods of determining the frame size, and they are as follows:

Method 1 – Inseam Length (How to Measure Bike Frame Size Using Your Inseam)

If you want to determine the correct frame size without referring to any guide, there is no better way to do it than to use your inseam length.

The inseam length is your inside leg length, which you can determine by following these steps:

• Remove your shoes and stand straight on flat ground with your legs 6-8 inches apart
• Measure the distance between your crotch and the ground in cm to get your inseam length
• Depending on the type of bike that you want to buy, use the inseam length to calculate the frame size using the details in the table below.

If your inseam length is 78cm, for example, and you want to buy a road bike, you should look for a frame size that measures 54-55cm (78cm X 0.70).

Method 2 – General Bicycle Frame Size Chart

Below is a general bike size chart that you can use to buy any bike.

The chart looks at one important thing, and that’s your height. If you match the bike frame size with your height, the chances are that the bicycle will fit.

Note, however, that I’ve shared a range of frame sizes, which means it’s not precise. So, if you intend to be more specific, consider method 3.

Method 3 – Advanced Bicycle Frame Size Chart

This method promises a more accurate bike frame size. In this case, you’ve to pay attention to the bike type you want and then match your height with a corresponding frame.

So, it’s no longer about generalizing as bikes as road bicycles and MTBs differ in frame sizes.

Now, let’s look at the sizing guide for all these bike types.

1. Road Bike Frame Size Chart

Road bikes mostly come in two styles; sportive and racing.

Sportiv road bicycles have a shorter top tube length, while racing road bicycles have a longer top-tube length. But in recent years, there has been a rise in adventure road bikes and cyclocross.

Even though manufacturers may have different sizing guides for their road bike subtypes, most of them tend to use the sizing chart below.

So, consider it to find an ideal road bike frame size (in cm).

2. Mountain Bike Frame Size Chart

Mountain bikes are engineered for off-road cycling. So, they come in the most robust frame size.

Their frames are measured in inches and cm, and their sizes range from X-Small to XX-Large. So, your job is to match the frame size with your height, as shown in the table below.

Note, however, that since mountain bikes come with different wheel sizes (26″, 27.5″ & 29″), there could be a slight difference in the bike size.

But if you use the above chart, you’ll rarely get the size wrong.

3. Hybrid Bike Frame Size Chart

Note that hybrid bikes come in different subgroups such as:

• Comfort bikes
• Performance bikes
• Dual-sport bikes
• Sport hybrid bikes
• Commuter bikes

So, all these subtypes employ the same sizing model.

Note that most hybrid bike manufacturers measure the bikes from the seat tube top to the bottom bracket.

Other manufacturers, nevertheless, use different sizing models. The most crucial point, however, is to ensure the frame size matches your height.

Hybrid bike frames are measured both in inches and cm, just like mountain bikes, and their frame sizing guides are the same as shown in the table below.

Ensure, however, that you have at least a 2cm stand-over height whenever you buy a hybrid bike.

4. Beach Cruiser Frame Size Chart

The difference between beach cruisers and the other bikes discussed above is that they come in sizes for all ages. So, you’ll get beach cruisers for kids and adults.

For that reason, you have to consider the frame size and the wheel diameter and match them with your age or height.

If I were you, I would consider the height over the age as it’s more precise.

Here’s a reference sizing table you can use.

5. BMX Bike Frame Size Chart

BMX bikes have been known as one-frame bicycles for a long time, with only the wheel size coming in variations.

For that reason, we won’t focus on the frame size as it’s unreliable in this case. We’ll focus on the wheel size instead.

And when talking about the wheel size, you’ll mostly have to choose a 16″, 18″ or 20″ wheel.

Note, however, that some BMX nowadays come with 24-inch wheels , and a perfect illustration is the Mongoose Title Elite 24 Race BMX (View on Amazon)

For such, you’ve to see what the manufacturer recommends. For others (20 inches and below), you can use the table that follows.

6. Gravel Bike Frame Size Chart

Gravel bikes are a type of road bike, which means you can size them like regular road bikes.

Nonetheless, some gravel bike manufacturers employ gravel-specific size guides that slightly differ from traditional road bikes.

Here’s one table that most of them use.

7. Womens Bike Frame Size Chart

Women naturally have a smaller stature than men. So, their bike frames are smaller than men’s.

However, you can expect a slight difference when sizing women road bikes but no difference in MTBs and hybrid bikes.

Unlike men’s bikes, we don’t have bike frame sizes for women over 6’2″.

Below are two tables you can refer to.

Women Mountain Bike and Hybrid Bike Frame Size

Women Road Bike Frame Size

8. Kids Bike Frame Size Chart

Kids’ bikes are not sized like adult bikes. While adult bicycles are sized according to the frame size, kids’ bikes depend on the wheel size.

In that case, you have to consider the rider’s height and the inseam length.

The inseam length, in particular, gives a more conclusive bike size. But still, most manufacturers use the age to measure kids’ bikes.

If I were you, I’d consider both the rider’s age and height. But overall, the rider’s height is more accurate than the age.

It’s essential that your kid can touch the ground with both feet, and that’s where the inseam length comes into play.

Here’s a sizing table to use in that case:

9. Specialized Bike Frame Size Chart

Specialized has a unique styling guide for their trail bikes. It grades the frame sizes into six sizes, all corresponding to a specific height range.

Usually, the bigger the frame size, the more stable the trail bike is likely to be.

Here’s a table from Specialized.com that you can use for direction.

10. Trek Bike Frame Size Chart

While Trek tends to size their road bikes like regular ones, they have a different approach for their MTBs.

Trek employs an alpha sizing model, which according to them, is easy to understand. According to the alpha sizing model, MTB frames come in four sizes, as shown below.

So, you only need to pick an alpha size that matches your height.

What If You Get the Size Wrong?

As far as your cycling health and fitness are concerned, it’s best if you ride a bike that fits you.

A bike that’s extremely smaller or excessively big is a safety and health risk. Health-wise, you’ll strain your back, knees, and shoulders, and that could result in severe pain.

Safety-wise, it will not be easy to maneuver the bike safely. You are likely to struggle and could easily crash.

Overall, if you cannot stand over the bike, the bike is too big. And if you cannot bend the knees, then it’s too small.

So, what should you do in either case? Here’s my advice:

Is the bike frame too small?

Consider these possibilities:

• If the seat is low even after pulling it up, consider getting a longer seat post
• If the stem is smaller, replace it with a longer one
• Move the saddle slightly back to create more leg extension room

Is the bike frame too big?

If yes, then consider these possibilities:

• Get a shorter seat post if what you have is longer
• Swap the stem with a shorter one if that’s longer
• Tilt the saddle slightly forward to give you a more comfortable handlebar reach

How Do You Ensure You Don’t Get the Frame Size Wrong?

Though the sizing chart is essential, it doesn’t always guarantee that the bike frame will fit. So, what else can you do?

In addition to looking at the advanced bike sing chart, consider these essentials:

a) Stand-Over Height

The stand-over height refers to the vertical distance between the bike’s top tube (crossbar) and the ground. Generally, this height influences your overall cycling comfort.

So, you have to confirm that you can stand over the bike with both feet touching the ground. In that case, there should be at least a 2-inch allowance between the top tube and the crotch.

b) Saddle Height

The bike saddle is another component that has a massive bearing on your overall cycling comfort. If the bike saddle is high, you’ll have a hard time steering the bike.

Luckily, you can adjust the saddle position. So, pick a bike whose saddle height you can change.

c) The Reach

The Reach (the handlebar-to-seat distance) also determines your comfort. Note, however, that the Reach is only essential for road bikes.

It’s not only vital for riding comfort but also cycling efficiency.

You can know if the Reach is correct by looking at the axle position when you take a seat. If the axle is in front of the handlebar, the Reach is short, and if it’s behind, the Reach is long.

The good thing about the Reach is that it’s adjustable. You’ve to be careful, nonetheless, not to mess up with the bike handling.

d) Leg Extension

It’s also essential that your legs also have enough room to flex when cycling. You can do that by adjusting the saddle height.

But if the seat is at its maximum height and you cannot extend the legs, the frame size is likely small. Thus, getting a more oversized frame is advisable.

Overall, you should have a 15-20 degree knee bend to offer you the correct leg extension.

1. What Size Is A 20 Inch Bike Frame?

A 20-inch bike frame (referring to the frame size) is an adult bike that suits riders who are 6’2″-6’4″ tall.

2. What Bike Size Should I Get For My Height?

You should get a bike frame size that matches your stature. Here is a general guide you can use to match a bike frame with your height.

3. What Size Is A 56cm Frame?

A 56cm frame is a large-size road bike frame that suits 5’9″-6’0″ tall riders.

4. How Do I Find My Best Bicycle Frame Size?

The easiest way to find your bike frame size is to calculate your inseam length in cm. Once you have the value, multiply it as shown in the table below:

5. What Does A 26 Inch Bike Frame?

A 26-inch bike means that a particular bike comes with 26-inch wheels. Ordinarily, a 26-inch bike suits riders who are under 5 feet (150cm).

Note, however, that some 26-inch bikes come with much bigger frames to suit guys who are taller than 5 feet.

Closing Thought:

Now you have the ultimate bike frame size chart, or should I say charts? You can thus use them as your reference to find yourself the most comfortable and fitting bike frame.

Trek 7.5 FX Hybrid Bike

• USER REVIEWS

As an in town commuter for Sacramento Fencing Pros , this is quite simply the best bike I've ever bought. It's fast,agile, and extremely reliable mechanically. As for those that say the brakes are finicky, I can't say that I've seen that on mine, even with me putting over 3000 miles on mine in the first year.

None so far.

Fast, efficient, great power to speed ratio. Great, easy gears. Great brakes. No damage after 5 years use. Safe. responsive.

Worry about rust on front brake.

Light weight, very smooth ride. Upright riding position, Deore rear derailleur. Feels like a road bike.

Shifting on front chain ring is somewhat poor.

Just got a 2014 model on sale at lbs. This bike is definitely worth the price! The Isozone and carbon fork smooth out all the road vibration and I like the road bike gearing. The compact double still allows for me to climb some steep hills in the saddle. The Deore rear derailleur shifts very crisply every time. I like the black paint. The only complaint is the "clunky" shifting on the front chain ring. I had a 2010 7.3 FX that I rode on BRAN in 2011, after that bike was stolen I missed it for almost 4 years but no more, the 2014 7.5 FX is awesome! A road bike in disguise!

2010 Trek 7.3 FX

Let me start by saying this is not a hybrid. Trek classifies this as a fitness bike. As an in town commuter, this is quite simply the best bike I've ever bought. It's fast,agile, and extremely reliable mechanically. Mine is the 2011 model with the hydraulic disc brakes. As for those that say the brakes are finicky, I can't say that I've seen that on mine, even with me putting over 3000 miles on mine in the first year. In fact,other than adjusting for cable stretch, I had absolutely no mechanical issues with mine. None. The only thing I changed on mine was the tires, I switched the factory tires for the 110 psi Racelites, which boosted the top end performance immensely.

The only problem I could point out is that it's not terribly good on loose surfaces. So I simply modified my routes to avoid areas that have loose gravel etc.

This was an outstanding bike for the money. It's a shame Trek dropped it in their 2013 line up. If you can get one used, I wouldn't hesitate to say grab it.

Light & Responsive. Carbon fork is easy on the elbows. I never had a problem with the seat once I started wearing cycling shorts. It is like a road bike for people who don't want a road bike. Well built.

Lever for front derailleur (left hand) is tough on the thumb as a lot of pressure is needed to change the gear. Not a problem with the rear (right hand).

I have a 2009, bought in September of 2008. Previously, I had had a GT hybrid for 13 years. This Trek was much lighter. I have never had a flat tire with this one! I bought the bike at Metro Bikes, NYC. I brought it in for yearly maintenance. It never needed anything else, except new brake pads. I did upgrade, after several years, to pedals that I could clip into . Eventually, in Sept. of 2012, I decided to up the ante and ride with a bike club. They all ride road bikes, so I am making the switch. Also, for me, I thought that the varied hand positions on a road bike would be better for the health of my upper extremeties as I begin to approach and will soon exceed 50 mile rides. But for 35 mile casual rides, this bike fits the bill!

Great bike for the price! Have had it 18 months now and put 3400 miles on it. Changed tires and went with Continental Gator Skins, just for a change and I'm well pleased with them after about 250 miles. Ride is smooth and changing gears a breeze. At 70 years old, both of these is a real plus. Had a vine catch my helmet last month and got a double flip off the back end of the bike with a lot of road rash to my knee, leg and arm. Bicycle took it hard laying down on the pavement. Twenty min. At the bike shop and she was looking just as good as before the accident.

None considering the price.

Bottom line, I'm More than satisfied. It answers my need for exercise and a daily hobby. In my area, seashore NC , we enjoy pretty good winters most years so I'm able to use the bike year round. Looking forward to many more thousands of miles, God willing. Two Wheeler Dealer in Wilmington, NC is where I purchased the bike and all my incidental equipment, clothing, etc. Can't say enough good things about them and their staff. Very professional and helpful in every way.

Have put 200 miles on my 2013 Carrera Blue 7.5 FX and I truly LOVE this bike. My previous ride was a 7.3FX and I'm very happy with the upgrades which include carbon front fork, monostay rear frame and 24 spoke rims. The carbon fork and monostay frame do seem to smooth out the ride. This the derailer is the same as what I had on the 7.3 but this thing shifts liek a dream, fast & sure. The brakes are outstanding. I ride paved roads, side walks and bike trails and this this performs like a dream. Added a node 2.1 computer, rack and new seat.

Seat was not comfortable, changed it before I brought the bike home

Putting lots of miles on this bike, riding it is a pure joy, very pleased with the purchase. When Trek added the monostay frame and offered the 7.5 in Carrera Blue, made the decision to buy immediately. Loved my 7.3 but everything about the 7.5 is more refined, more high performance. Getting used to 18 vs 24 speeds. I'd probably prefer 24 but the move to 18 is not that big a deal, use every gear and have had no issues. Was a little concerned about the 700x28 tires on sidewalks compared to 700x32 on the 7.3. No issues, they wear like iron and handle like a dream. The paint job and graphics on this bike are outstanding, I love just looking at the bike. Very happy with my Trek 7.5FX, intend to own this bike for a very long time and log thousands of miles. .

Good riding position for an old guy with an 'iffy' lower back. Did RAGBRAI with it this year and had zero problems w/ it. Our team propbably ranked in the top 25-30% of finishers each day so we were not dawdling out there. Shifters work well [now better than when new]. Chain ring shifts are slow and must be held when shifting into big ring for a moment to avoid chain issues. Not a deal-breaker but I did have to adjust to its character. Brakes are superb; I have the disc brake model and they're fade-free wet or dry. My Trek bike shop exemplifies 'customer service'. It's a very smooth roller and often I an outcoast the racing bikes costing several thou more.

Bottom bracket started making noises ~3 months old and a 'clicking' noise was there sometimes and then not - hard to diagnose. Finally, it was determined to be a bracket failure & Trek replaced in an expedited fashion. BB's have a 7K-10K? lifespan but I had less than 1K on it when it failed.

Good, solid machine for what it purports to be. It's rugged [I'm a 215 pounder & it's taking me on nicely]. It's too heavy to be a pure road machine but if you utilize 700x23's on it, it will keep up with most of the traffic on a typical ride. I may add a graphite-framed road machine to my stable for use with the longer rides or to add that extra 2 mph to keep up with the kids. I'm 69. :-)

Poorly made

Let me first say that I am 6'2 and i weigh 250 lbs. With that being said, this bike is simply not made for a large man or woman. I have to repair it after every ride.

Strong, stylish,light weight. Responsive gearing.

Poor pedal bearings, breaks need adjusting a bit too often.

A great all rounder, quick and responsive. I cycle 50 km daily and find the bike to be comfortable, easy handling and of reliable quality albeit the poor breaking and inferior pedal bearings. I have cycled 3000km since I purchased my Trek 7.5 and am at the end of the day not sorry.

Trek 8.4 DS XC Hardtail

• USER REVIEWS

Frame looks good with nice lines and while this is an individual thing, the 19" version fits me about as perfectly as any bike ever has. The hydraulic brakes offer great feel. I liked them more than I thought that I would. Grips are also above average for stock. Wheels and tires offer nice mix of better than average roll with some light off-road ability. The chainstay port for the Duotrap is something that I took advantage of and it works quite well. It is pretty neat and tidy and I have it mated to a Bontrager 300 computer. Overall, pretty slick. I have a few bikes in the stable but if I lived in an apartment still or some other situation where I had to pick one jack-of-all-trades, master of none kind of bike, this would be on the short list. I got mine second-hand but after riding for several weeks, I thought so much of it that bought my wife a brand new one.

Suspension fork isn't going to win any awards but it gets the job done for the type of expected riding you're likely to do and they also look quite nice with color-matched paint to the frame. In red, mine really pops. It does have a progressive lockout dial but the limited travel and old-school spring will really be a step down for those used to air shocks on their mountain bikes. The stock saddle and pedals had to go but I can't remember a bike that I haven't said that about in the last 20 years- Anyway, those minor issues were solved with some modestly priced upgrades.

Great all around bike, good on the road, rolls fast. Hydraulic brakes, shifting, geometry (for larger man). Looks

Single wall wheels on stock bike, pedals, Local Trek store (Pittsburgh area)

OK I am writing a review after riding over a 1000 miles on my 2014 8.4 DS Gary Fisher edition. It should be similar to the newer models. I starting looking at replacing my 18 year old Trek 800 last summer. The bike had been nails for that entire time and was going with my son to school. I of course was focused on Trek, though my wife has a Giant(and loves it) and looked at those and a few others, though was partial to Trek. I actually was looking at the FX series but the guy at the Trek store pointed me to the 8.3 and 8.4 DS. I liked the 8.3, but noticed a big difference in braking and shifting in the 8.4 and absolutely loved. Also loved the fact that I could take off road (though not too off with the 700X38 tires) and it was much better on the road, where I do most of my riding, with the larger and narrower wheels. I have ridden over 1000 miles since last August and have loved the ride. Until June it required no maintenance, not even a cable adjust. Just chain lube and pedals (see below). However in June, while riding on a flat, paved trail, a spoke broke. I didn’t think much of it, called the Trek store and they said it would be 7 to 10 days to fix. I took to my LBS I have been going to for years (Giant dealer) and fixed same day. When I broke another spoke in August, I thought this is not right. Took to the Trek store and they gave me some hassle about need to verify the warranty (7-10 days)and If I wanted it fixed it would be 5 days or pay an extra $22 to move up the line. Additionally they told me the wheels where not very good and I needed to upgrade components. I told the kid that’s not what you should be telling people that have purchased a $1000 bike (actually $900 with some add ons). I did say while I did not spend $3000 or more on a mountain or road bike, it is still a lot of money and I don’t expect that. I took back to my LBS and he fixed again in a day. He did tell me it should not be happening and though he thought that type of bike should have a double walled rim (like the comparable Giant) it should not have happened with the type of riding I was doing. I emailed Trek customer service and within a couple days got a call. The guy on the phone was great, said he himself loved this bike and agreed this should not happen. He had a new TLR wheel sent to my local Trek store and they installed in about an hour. The mechanic I got this time was very nice, and agreed this should not have happened on the AT650 wheel. He was glad Trek was taking care of and said I should expect no more issues with the TLR wheel. Overall a great bike if you are an all-around rider. If you are going to just ride roads, or trails, probably a purpose built bike would be better. But if you like to mix things up this is a great bike. It has the clearance for larger tires so you can do more off road. Hydraulic brakes are fantastic, shifting has been great. I have read on some other blogs that the front forks don’t have enough travel, but I have not had an issue with it. Again if you are going to do heavy mountain biking, probably a purpose built bike is better. Also read another blog that did not like the tires. The 700X38 tires that came on the bike have a low knob, and you do get some tire whine on the road, but the fact the tires can go off road is what I like so I have no issue with that. However if ride on loose surfaces a lot, my want to get a wider tire. Only other con is the pedals. They are aluminum cage with a resin spindle. They started clicking after about 700 miles and required lube ever 2-3 rides. I have since switched them out. Outside of the issue I had locally, this has been a great bike and would highly recommend.

Strong frame. Strong brakes, once they break-in.

Fork seems loose and rattles. I thought at first the headset was loose.

I chose this bike for my latest electric conversion for the strong frame, large wheels, tall gearing, and hydraulic discs. I was able to mount 29x2 puncture resistant road tires, but the clearance to the front derailleur is tight. It only took me four tries to seal the front rim while converting to tubeless. With the suspension fork, 35 psi in the tires, and a Thudbuster seatpost, this bike is comfortable enough for everyday commuting. I'm not sure about the manufacturing precision of the brakes, but this is among the lowest costing bike with hydraulic discs. I had to readjust the front after removing the wheel once, and the discs look slightly warped. For the road, they work very well. I have no problem slamming them on stopping at a light at the bottom of a hill. I also had a lot of fun mounting the rear battery rack. The rear caliper was slightly in the way. It took a few washers and longer screws to mount securely.

Although it looks more like a mountain bike with skinny knobby tires, don't be fooled. The bike is FAST. It will pretty much take anything the road has to offer and doing it smoothly. Other than the knobbies on the road, the bike gets 4.5 outta 5 in my book. Traction was surprisingly very good uphill as well. I don't think I slipped once, unlike my Rigid with the Kenda the SB8's, if I stood up at all to climb, I’d lose traction. I also think the non slippage is due to the larger 700x38 tires. More surface to contact to the ground.

The Suntur fork with 63mm of travel is fine for most mild trail applications. For rock gardens and fast 30+mph down hills, this fork can be pretty uncomfortable. The 63mm of travel bottoms out on really hard hits and with just sitting on the bike, it sags about 30mm so in reality, you are getting only 33mm of travel. The only other weakness is that you are limited to going only a 29x2.0 rear tire and nothing wider or it will have no clearance for the front derailer. That is if you wanna go more hardcore MTBing, then i would recommend get a MTB.

Overall, the 8.4 did its job. Most riders told me I should have just gotten a mountain bike since I ride the mountain at least twice a week, get a purpose-built bike, etc., etc. I think that is just what I have done. Its purpose WAS to do BOTH Road and Mountain. And to test the 8.4 on the Loop is a great indicator of how the DS 8.4 can handle the abuse. The tires held up, but would definitely change them to wider tires if you plan on going mountain biking a lot. Same thing with on-road, if you plan on going faster, more on the road, go with the skinnier slicks. So to conclude my review and thoughts, the Trek DualSport 8.4 delivered. Those Trek Engineers along with Mr. Fisher himself did a great job! The only other thing that happened was the lock out switch popping off after bunny hopping over a branch. I didn’t notice this until I was done with the ride and saw it was gone. Luckily, it was on the ground at the beginning of the ride, but been run over by bikes and whatever else that went on the path. I can totally see why the remote lock out would be the better choice..the switch is plain CHEAP. Fail on this part. Nothing to hold the switch in but friction..so i put silicon on it to prevent it from popping out..hopefully it stays. I do like the remote lock out idea. For now, now that I know the 8.4 can take what I have to give it, I will be happy going to the Fullerton Loop and the Santa Ana River Trail for a while, enjoying the ride and staying fit.

Good for light trails, fast on streets. 27" tires, strong MTB frame., Comfortable and fun to ride.Excellent Hydro Disk Brakes.

None to speak of.

Great all-purpose bike. Can be used as a commuter, street bike or on all but heavy trails. If you can't decide between a road or Mountain bike and only want one bike, this could be the one for you.
