Strengths:    The suspension is incredibly fluid and can take a beating. The shifting is flawless. The brakes stop on a dime. The seat is WONDERFULLY COMFORTABLE.

Weaknesses:    The tires don't have a lot of grip, I've fallen a few times because they simply slipped out from under me.. whether it be from my poor riding skills or the tires, i'd like to get some tire ones to improve my learning curve. The front brake transferred the film from the caliper poorly so there is friction on one disk, but I can;t even notice.

Bottom Line:   
I picked this bike up for $1300 at a trek bike store because it was on sale and we talked the individual down a few hundred. It's my first bike and I love it. The suspension I that came with the bike was a rock shox recon gold air fork in the front and a fox float rp2 in the rear, so i don't know why everyone has a rockshox rear shock. I would recommend this bike.

Strengths:    xt rear d, fox rear shock, recon front, elixir 3 brakes

Weaknesses:    cheap shimano crankset, crappy bontrager xr4 tires.

Bottom Line:   
I very excited about the purchase of my first full suspension. i took a hiatus from mountain biking and was road biking during that time. its good to be back. the feel of the trek frame is great especially with the ABP. ill replace the weaker components as time goes on. but for the money it was a good buy. i enjoy it.

Strengths:    Price

Weaknesses:    Weight
Rear Shock

Bottom Line:   
Bought this bike 6 months ago from Craigslist. I have been satisfied with the quality of the components with two exceptions, the Bontrager Jones XC tires are downright dangerous for anything but flat paved roads. The stock Rock Shox MC 3.1 is difficult to adjust and upgrading to the Fox RP23 improved the overall experience. Although the weight of the bike is quoted at 31.9 Ibs, it actually feels lighter on the trails. Climbing with it is not a problem. The cockpit seems a little tight (I'm 5'8" and weight 158 on a medium frame). Maybe a larger frame would be better. Climbs better when seated that standing. Dialing the correct pressure in the fork and shock makes a day and night difference. For the price, I cannot complain

Strengths:    solid feel up and down, climbs well for full sus, feels bottomless, hydraulic brakes are great, comfy, shifts well, quiet on trail so far

Weaknesses:    build parts are middle of the road, not bad for price level though

Bottom Line:   
bought as an xc/marathon racer and trail bike. tried full sus prior in the 90's, not so good, recently a dos niner for a lap on my local trail. was going to build a dos for next season, but saw this on sale and it was my size!

first off this thing stock weighs less than my redline 29er, no scales just pick both up and see, there are no scales when you have to carry it up steps or a rocky hike a bike. bike feels lighter all around.

after suspension was set in the yard and on my local gravel road, off to the trail i went. local loop is a great all around east coast trail- rocky rooty steeps mud leaves log crossings bridges.... this bike handles all very well and my learning curve with the bike was very fast. i had to adjust all my shift points, and braking markers on the 2nd lap. i was finding time all over the place and it felt fast too.

i spent alot of time getting the spring rates/psi correct for me and my riding style and then adjusted the rebound to suit. i started per the guide, that was too soft, sus set one step higher than suggested by weight, rebound as directed for weight.

as far as pedal bob, i can make it happen, but if you have any tech skills and know how to spin, and can apply power while spinning, not just mashing, then you can get off the seat and push this thing uphill. all that with propedal off!!!! later i will lock the front and turn propedal on and go for lap times and see which is faster.

overall this is a great full suspension trail bike that i will race cat3/cat2. it isnt the lightest, but i want to be sure and finish, not just have a superlight ride. it also fit my budget and can be upgraded over time.

Date Reviewed: October 10, 2010

Strengths:    I have abused this bike for 10 months and it has taken it like a champ. I weigh 220 and huck my bike like 100lb kid. The Fuel feels stiff when I need it(climbing) and cushy on a brutal rock garden or an abrupt landing. I love this bike.

Weaknesses:    The rear supension, Rockshox mc 3.1, tends to quickly eject at inopportune times. I haven't messed enough with the motion control to have it dialed in, but it kinda works wierd.

Bottom Line:   
I am getting a jiggle in the swingarm/rear suspension. I have to take it in to get the bushings replaced. All the bolts that hold it together are taunt, but it still wiggles. Anyone ever experienced this or better yet, repaired this problem. It just started and I hope it is not fatal, I love this bike!

Date Reviewed: October 21, 2009

Strengths:    Stock as far as I know. Avid Mechanicals are great, and I'm a big fan of the sram x-7s-thumb thumb shifters. Also, the front fork seems to compress and rebound just right.

Weaknesses:    First of all, the rear suspension is hideous. And second, it seems to ride funny, I think mine just needs air, but it there is practically no rebound while there is weight on it.

Bottom Line:   
I picked the pick up hardly used at all from a friend. I own an Iron horse 7.3 and I ride downhill/freeride. This Trek Fuel is going to be my entry bike into xc riding. It seems great, I just want some different tires, and I want the rear suspension (rockshox MC 3.1) to not feel so damned weird. As stated, I think it needs air. I would say, if you can pick one of these up super cheap, it's a steal! I suggest this bike for anyone who is just getting into xc riding and wants a good place to start. It's so light compared to my DH bike, I can't wait to upgrade and make it even lighter.

Strengths:    Overall, this bike has held up well and I just hit 1,000 trail miles since buying this in June 07 as a rental bike!

Weaknesses:    Sometime creaky rear shock, pedal bob when I stand up while climbing. Seated climbs are no issue.

Bottom Line:   
I really can not complain too much about this bike even after 2 years. Not too heavy, climbs decently as long as you don't get out of the saddle. After 1k on this bike, I still enjoy riding it.

If you can pick one of these up for cheap, it would be worth it. I am looking to get a SS 29"er and keep this bike as well.

Strengths:    Components functions as they should

Weaknesses:    The Suspension

Bottom Line:   
In reading the other reviews on this bike I am a little surprised by the overall satisfaction that other users are describing. I have not been very pleased by this bike. I would do anything to get my old Klien back. When the frame broke on the Klien I contacted Klien and b/c they didn't make that model they gave me store credit for $1000.00. What company does that after 11 years. Another testament on how cool Klien is. I got this Trek and immediately had to get the front shock sent back to the factory and Trek sent me back a totally different shock - brand new, which was nice, but a little worrying that it had issues. Other users have said you have a toy a lot with the back shock...maybe I'm an idiot, I cant get it dial in...its' always to soft. This creates a huge problem, I can never "open up" on the trails. If I am coming into a turn, before I can lean with it I HAVE TO APPLY THE BRAKES, because four times now I've treated and rode the bike like my old bike and that back shock, compresses, then BAM explodes and unloads, kicking that bike tire out from under me. Round abouts are especially dangerous, I've ended up in the flower bed twice on the side of the round abouts b/c you can't throttle the bike and expect the bike to preform. In addition, I think it is a touch heavy, but for the price it is reasonable. I think I'd be happier if I had paid more money for a lighter faster bike...but that may be an issue of choice and expecting to much out this bike that maybe wasn't designed for normal mountain biking trails.

Strengths:    Great performing XC/offroad bike. Tuneable suspension.

Weaknesses:    Seat, Tires, squeaking/creaking pivots, shock was replaced under warranty after 1 month of riding.

Bottom Line:   
This is a great bike to get for someone making the switch from hardtail to full suspension. I noticed that my riding has improved greatly from the first ride on this bike. The confidence that this bike has given me has improved my speed to the point where I'm starting to think I might like a 5-6" travel bike. A few things to note: My shock had to be replaced after 1 month of use and the frame was creaking a lot at that point as well. The LBS replaced the shock and gave me a complimentary tune up which fixed all of my issues. One year later (about 300km), my frame pivots have developed a minor squeak which only seems to show up when it's hot outside. Also, the seat is terrible and the tires are only good on hardpack.

Strengths:    good value, very tough rims

Weaknesses:    cranks
tuning rear shock

Bottom Line:   
haven't had the bike long. previous owner had intalled new BB just before selling it. Since then I have had a big Issue with the splines on the Crank arm wearing and making my crank come loose every ride.
Also find the rear shock challenging to tune. requires too many turns of the dial going between lock out and trail tune. Good to pedal with dial wound up hard.
Love the rims, previous owner has never had to true them once. I hit things hard and still have no issue with them.

Otherwise very happy with the SRAM components. Just wish the bike was a bit lighter.

Date Reviewed: January 18, 2009

Strengths:    Great components for the price, especially with this year's increases.

Weaknesses:    Went through 2 MC3.1 rear shocks in 2 weeks and about 40 miles of riding before they finally replaced it with a MC3.R under warranty. Frame is absolute garbage, shifter cable not only rubbed through the paint but was rubbing through the metal when I finally noticed after about 2 months of riding. Additionally the paint was flaking off all over the frame.

Bottom Line:   
For the price I guess I can't complain too much, especially since I was able to sell it for about what I paid. Had I not sold it I would have probable gone after Trek to warranty the entire frame. It absolutely blows my mind that the shifter cable could actually rub away that much metal in about 100 miles of riding set up completel factory, no changes on my part.

Strengths:    Good climber if tuned right, price, drive train

Weaknesses:    Gets a lot of bob when not tuned right. sqeeky sound on rear shock when gate is open. Stock is a little heavy.

Bottom Line:   
The rear shock has to be tuned almost as stiff as possible to get the most efficient climb. It took me a while to get the gate dialed that compliments the amount psi pumped in. The stock rock shox tora is... errr... ok... the reba is just lighter and more reactive. If you have more money you'd be able to set this bike with a better fork. BOTTOM LINE is invest time to tune this bike and when you get it you'll feel the 5 chillis on how effective this bike is.
