Strengths:    It's lightweight, the drcv shock and fork is amazing, eternal cable routing, rims are tough, most people I ride with are on 170mm travel bikes and I do everything on this bike they do and also the things they can't like really technical rock gardens and long rooty climbs.

Weaknesses:    3x10 should be 2x10, handlebars to flat, bonty race light grips only good if you have tiny hands

Bottom Line:   
The people I ride with are all on 170mm travel bikes and I do all the downhills they do 5 foot drops etc but faster and also the stuff they can't do like technical rock gardens and steep rooty climbs. My next bike purchase will be a dh bike from trek just for the lift assisted runs that I plan on doing but for everything else I ride it's the fuel ex 8

Strengths:    For the amount of riding I do it's great! I beat my bike up and it takes a great beating. You get great components for the price you pay. The Fox Susp is awesome and the bike is lighweight!

Weaknesses:    The stock Bontrager tires are terrible!!!!!

Bottom Line:   
Awesome bike for the $.

Strengths:    Geometry - does not lift front wheel at ascends, does not want to get rid of rider at steep descends, or ,,unexpexted,, drops.
Rear shock - DRCV works well, but need precise set up.
SLX brakes - uncompromise breaking power (but cheap stock discs)
SLX/XT drivetrain - good enought for most riders
wide handlebars

Weaknesses:    DRCV fork - too linear, undermining bike´s potential...Definitely doesnt work.However, can be tunned by PUSH tunnig kit to be more progresive.
For rough trail ridig long stem.
no ICCG mounts and using BB90 - so I use Bionicon works, but sometimes chain drops...)
weird sounds from front wheel and frame (I learned to ignore)

For me personaly I needed to upgrade gear pads for xt, changed drivetrain to 2x10 (3x10 for trail ridind makes no sense.)
This bike is not equiped with dropper post, bought RS reverb.

Bottom Line:   
Very well for amateur XC racing(not fastest) and can handle some trails in bike parks. Perfect as a first full suspension bike, when you cant decide, what you want to ride. You can remain XC rider or... It is very capable descendant, so in short time you can gain trail-all mountain skills and will be looking for most demanding local trails and become ,,trail adicted,, as me:) So there is one more weakness of this bike - after one year of riding - you are looking for longer travel bike.)

Strengths:    Weight for the bike is really light. Lockout on fork and propedal on rear shock work like a hot damn for tough climbs. The full float platform absolutely rocks and it feels the best of all I have used which are many : DW, Maestro, KS link, VP free and FSR. I have decided any other bike I by from now on will need to be full float. Rims are tough!
The price is great.

Weaknesses:    The 9mm front qr is old school it would be nice to have 15mm other wise nothing at all

Bottom Line:   
I have tweaked my ride to my liking as I do with all my bkes. I added Haven bars, Turbine cranks, X0, SDG Duster seat (Love this saddle), TruVativ setback post, Ruffian grips, Cross Mark tires.

I noticed a big change with by dong all of this. Bike tracks great, free float system is unbelievable!!!! I used to hate pedalling my previous bikes up but now I really enjoy it since the bike is equipped with the lockout and propedal. MAN what a difference this makes. I have never dropped a chain and my bike shifts flawlessly.

I can honestly say I can shred everything on my rides. I ride for hours at a time and find this bike suits my needs for a true AM bike maybe geared a little more on the XC side. It has great geometry and is really light. I haven't found a time where I came back sore from riding just left wanting to ride more.

My next bike will be a Remedy since I hit everything on the way down.

Strengths:    This bike is a monster. Climbs well. It will descend like a champ.

Weaknesses:    The handlebars are way to wide for a medium and small frame. I have a medium size, the handlebars need to be cut some. The brake rotors are also to big for the medium and small frames. A person on a medium-small is going to weigh roughly 110-160 pounds. We don't need 180 mm front and 160 mm back rotor to stop us. It is a waste of weight to have all that extra rotor.

Bottom Line:   
I would most certainly recommend this bike to a friend. Besides the brakes and handlebars this bike has no drawbacks.

Strengths:    XR4 tires, DCRV shocks, full floater rear setup, component choices for the price, e2 headset,

Weaknesses:    No A/C, power windows or door locks.

Bottom Line:   
Previously, I had an EX5 and EX6. When the demo 2012 Fuel EX8 became available, I jumped at the chance to buy one at a great value. A world of difference between EX6 and EX8. When I took it first the first ride, I noticed how quiet it was (not much chain bounce) and this bike has been used a few times being a demo. It felt brand new yet well tuned. The best part I like is the front end. Together with the e2 headset, DCRV fork, XR4 tires and sturdy frame gave me confidence going fast downhill. It's not bad going uphill as well. The shifting was solid and responsive. The matte black color makes it a mean looking bike and easy to clean. I can just stare a this bike in the garage for hours but I'd rather ride it. Awesome bike!

Strengths:    Great bike for the price. Solid components (LX brakes, LX/XT deraillers, DRCV Fox RP2 shock and DRCV Float RL shock). XR4 are solid tires. The bike climbs well and feels fast and light on the trail. It has 120mm of travel but it feels like a lot more on the trail.

Weaknesses:    None so far....maybe a shorter stem...if you want to get picky.

Bottom Line:   
Have ridden this bike for 8 months now and it rocks! It climbs extremely well and the DRCV allows full travel of the fork and shock making it feel very smooth on descents. Tires are grippy (ride tubeless) and like others I agree on this bike making you want to ride.

Strengths:    This bike loves to be abused and man handled in the technicals. Components, brakes.

Weaknesses:    No navigation system.

Bottom Line:   
I made this purchase a year ago and have come to realize it has been one of the best purchases I have ever made. First off the color is amazing black with grey. It has good components for the price. One year and the first thing that went was my tire. so I switched to tubeless and it's a dream! I have rode several bikes around this same price range and realize that this bike was one of the best. Located out in San Diego I have used this bike through dirt, dust, mud, woods and must say it handled it all nicely. This is my first serious mountain bike and I did extensive research before purchasing and found it had many benefits like low brake jacking, great climbs, comfortable cruising and strong descents due to the 68 degree head unit. To be honest the bike makes me want to go out and ride. Not to mention the nice absence of brake jacking when rolling down big hills. This bike is good for someone who just wants to have a nice bike for the singles, and maybe do some technical along the way(although technical is all I use it for). Great beginner mountain bike for someone trying to build their skills. I don't plan on letting this bike go...ever.

Strengths:    Suspension works great. All components seem to work well.

Weaknesses:    none yet

Bottom Line:   
This is the 2010 model. I've had this bike for about 6 months and am still getting used to mountain biking (I used to be a road racer). The bike was in beautiful condition when I bought it and almost everything was perfect. The only flaws were that both the front and rear rims had one spoke bent on each (both were true). I've taken this bike on several pretty long rides (up to 30 miles long) on a variety of trail and terrain. The bike has performed flawlessly. The bike came with G3 rotors (185mm and 160 mm) which made a gobbling sound under braking. I changed to new HS1 rotors (180mm and 160mm) and the brakes perform very well.

I'm a conservative rider and have only had the bike up to about 35 mph on some downhills and it has performed very nicely. On climbs, the pro pedal works fairlly well. The bike originally came with bontrager tires and I changed them to WTB Velociraptors and they seem to grip pretty well. I'm going to enjoy growing into this bike!

Strengths:    Active Braking Pivot. Floating Suspension. Brakes and suspensions work independently. High-low chain stays make the frame look cool. Very light aluminium material.

Weaknesses:    Mine's a 2008. The headangle is not descend friendly.

Bottom Line:   
Very little/minimal pedal bob thanks to the Fox RP2 propedal and the floating suspension system. Weight of the whole bike will never be an issue I just love going trails with this bike. Climbs very well. Traction and braking is excellent. If you are planning to get a trail bike this is the answer. Don't have to look elsewhere.

Strengths:    Very solid bike, not only in feel but in build quality. It takes corners very well, and the DRCV technology works very well and inspires confidence. I love everything about the bike, the color scheme, parts, look and I find it to be light. It climbs great, and is a true head turner out on the trails. Takes anything you throw at it!

Weaknesses:    Most are complaining about the stock tires, mine came with the X4 Bontragers and I find them to very solid.

Bottom Line:   
If you have the money, definitely get this bike, great bike from a great brand. I looked at similarly priced bikes from other manufactures within the same price range like Giant, Specialzed, Cannondale etc but the Trek won me over, not just based on looks.

Date Reviewed: July 5, 2012

Strengths:    I've taken this bike on numerous single tracks like El Prieto, Mt. Wilson, and Chantry Flats and it's been great, except for a few things. I had to replace the seat since it got shredded up on a high speed slam on a fire road. Also, the grips are terribly uncomfortable so I changed those out for some ODI lock-on's which are holding up great. And finally, make sure to run tubeless! You won't regret it, I've had to buy 4 new tubes for this damn thing because of thorns. So the bontrager tires and tubes just suck, so if you can get Kenda tubeless they're amazing. Other than that the shifters are smooth and crisp and the suspension is a dream. Great bike overall and I'm riding it until it dies.

Weaknesses:    Tires and tubes it comes with are absolutely pathetic, seat is weak and isn't very comfy, and the grips are all uncomfortable. But those are mainly just small problems that are easy to fix by running tubeless, buying a WTB Rocket V seat, and buying ODI lock-ons. That's my opinion.

Bottom Line:   
Great bike for intermediate riders who are looking for a good, reliable, full suspension. And it can handle any terrain you throw at it so I give it a 4 1/2 out of 5 flamin' chilis!
