    Strengths:    Stability
    Handling
    Brakes
    Weight - Value
    Stand


    Weaknesses:    XC32 Rockshox fork
    Tires
    Crank bearing


    Bottom Line:   
    Bike handles great and you can really throw anything to it and in will take it. I am an aggressive rider and I have not have any issue with the frame or rims.

    On the other hand, I blew-out the shock after 300 miles on it (it was fixable), the threads in one of the cylinders stripped away. I changed the tires for better traction (original tires do not work well with Florida's sandy trails). And finally, the crank starts making a rubbing noise when you apply heavy torque while pedaling, and it will not go away until next time you ride - very weird.

    Overall, I am very satisfied with my purchase and I will recommend this bike for an intermediate rider, it will fall short for anyone beyond a weekend warrior.

    Strengths:    Great handling, well balanced and bike feels very stable and can handle the trails.

    Weaknesses:    The Hayes Dyno Sport Disc Brakes

    Bottom Line:   
    The rear brakes after 32 miles (2 trips) of riding on a glorified XC Trail that involved heavy use of the brakes due to gravity, I ended up "burning them out" (rear) as the LBS put it.

    This is an upgrade from an older 26" hardtail with the center pull style (Shimano Deore LX). Never had brake issues even when riding on lift serviced MTB trails with previous bike.

    Overall the bike is extremely stable and does handle well which I believe is all due to the frame design of this bike. I've only trail ridden 5 times since purchased. Two trips were more gravity based. The other three were climbing and trail blazing

    I'm used to Shimano LX and XT level of equipment and can feel the lack of precision in the Shimano Acera and Deore derailers. I was aware of the components used on this bike or any other at this price point. Overall the bike's components I feel are durable (except for the Hayes brakes).

    Overall this is a great bike to hit your local trails with.

    Date Reviewed: July 26, 2013

    Strengths:    Frame, drive train, fork, all mountain

    Weaknesses:    Tires, brakes

    Bottom Line:   
    I upgraded to the mamba from a 2006 Gary Fisher Tarpon 26. My first impression on the mountain had me concerned about the brakes. But by adjusting the lever placement and just getting used to hyd discs over rim brakes, I am very happy. Disc brakes are meant to give you more control, therefore reducing the chance of losing traction. If you adjust for the long lever pull, these brakes are effective. That being said there is no mechanical adjustment for the long lever pull, which IMO on a 1000 dollar bike is ridiculous.
    The tires seems to be meant for more XC rather than all man, the roll fast but leave something to be desired in the loose and mud. I've upgraded the front to a more aggressive tread pattern.
    The rest of the bike is amazing, the rock shock paired with the 29s have really boosted my confidence. The drive train is strong, and the G2 geometry really seems to work for me. I'm 6'2" and 250.
    Not really important to me, but the flat black paint looks good.

    Strengths:    Nimbleness

    Weaknesses:    Brakes

    Bottom Line:   
    This is my first 29er so I'm not sure that this counts. Compared to my other mountain bikes this thing strears great, awesome I would say. I ride street and dirt bikes so I might be expecting too much from the brakes. Yes I would like something better. To me this bike doesn't feel like its 30 something odd pounds. I feel like any kind of upgrades that will need to be made are inevitable on any bike you buy. The price and the reputation I think is with a lot. I've already put 44 miles and it not even a week old. I haven't ridden in over a decade that's how enjoyable this bike is to me. I think once you ride this bike you'll realize that 1,000 bucks will bring a big smile to your face.

    Bought bike new last fall rode it twice and put away for the winter. Thought about going for a ride inn the spring and back tire was rubbing frame . Took to lbr and found frame was cracked. Trek said water had cracked the frame even though bike was in garage . Trek said it will not cover it under warranty but if I wanted I could spend more money and buy a used frame. No thanks Trek I will stick with Rocky Mountain there frames seem too last

    Strengths:    Overall I have found this bike really comfortable to ride and responsive to what I want and need. Overal, an adequate bike and rides well on all surfaces.

    Weaknesses:    I have found the stock tires to be less than great on loose soil and gravel mixes. The bike really seems to slip like it is going to slide out from under you in both dry and mud. I am definitely going to replace. After two months of use, tires don't seem to have longevity written on them, although they do work well on hard pack/asphalt situations.
    I broke the chain in one month. The coupling links peeled apart like a banana skin. Trek upgraded the chain no questions asked. The local guys like Shimano and this chain is doing well.
    Brakes also seem a little weak on downhills. Most definitely going to replace.


    Bottom Line:   
    Overall, I have found this to be a good bike. Some of the parts are not really what I had hoped for given the price, but overall I feel that it is a good value. I don't see myself really having to replace a lot of parts immediately and the overall quality seems to be there on all the stock parts even though they may not be all that great long term.
    As I am new to the sport, some of the maintenance instructions that come with the bike are sorely lacking specifics. Most definitely will have to get some additional reading material.

    Strengths:    Decent drivetrain as compared to similarly priced competitors.

    Weaknesses:    The XC32 Rockshox fork. Area between dropouts on fork measures 98.5mm so a standard 100mm bike mount can't be used without grinding 1.5mm off the mount. I called Rockshox tech support who said the tolerance is 98-102mm. That's bogus. Nobody I've spoken to anywhere has ever experienced this with a fork. I went back to the bike shop and the fork on another mamba was the same way. Tech rep said they can't control the aftermarket bike mount makers like the exactly 100mm mount is their fault, not Rockshox.

    Bottom Line:   
    If not for fork issue I would give it a higher rating.

    Strengths:    Looks nice.

    Weaknesses:    Brakes! I have broke them in as you should. I am not sure if they need bleed off or what? I can grab both front and rear as hard as I can at 25mph and never lock out my rear or front start to pull up my rear. I bought this wanting a wet system and now miss my V-brake and kona I sold to get this. It's been in the shop twice now. I bought it on tue April 9th today is Friday the 12th. First the neck started to flop around. No big deal, they tightened it up and shipped it out the door. Today the front wheel is bending under torque from the brake system that half way works. Taking it in after I write this up!

    Bottom Line:   
    Not happy with the product I have received! I feel that the shop that I bought it from should have a grasp at how to put a bike together being you have to be a dealer to get one from trek. Even after I get it back and say its good to go I'm selling it on local bike classifieds. I have had many 1000$ plus bikes and never had to bring them in on the first day or twice in three days of ownership! I'm glad I did not buy my wife's bike the same day. We will be getting new bikes as soon as I take a loss on this bike that's seen maybe 20 miles of street riding and 2 trips to the shop.

    Strengths:    geometry, front shock for bike price range, hydro brakes

    Weaknesses:    tires, saddle

    Bottom Line:   
    Bought my Mamba in February after doing a lot of research on really nice medium level 29er's. Love everything about it...minus tires. Too narrow and do not grip the best on the trails. Saddle is pretty hard also, looking to upgrade in the near future. Rides amazing on the trails, adjustable front fork goes a long way when riding through different terrain, and lockout feature is great for in town riding.

    Bottom line: Bike is awesome for the price, and according to most of the guys at the LBS's it has better components than the 2013 models. May want to invest in some wider tires but that is about the only major complaint I have. Great bike!

    Strengths:    Ridgidity of frame
    Geometry-strictly personal
    Suspension
    Rims


    Weaknesses:    Tires
    Brakes


    Bottom Line:   
    Bought this bike for a Moab, UT trip. Glad I did. I did not want an XC due to my everyday riding, cost, and weight. 29" made a huge difference on rocky trails. I will replace rubber this year as the Bontranger rubber is just adequate and wears quickly. Hayes brakes worked well enough but there seems to be noise from the discs. Shop will check them out. I needed to tighten the head stock on the trail as it had a little too much play for my liking. This could have been the retailer prep.
    Overall, I am really happy with my choice and with a couple of tweaks, total satisfaction will be had for a few years to come.

    Strengths:    I'm told if you love your frame, your love your bike. With this in mind I love this bike. Theirs room for upgrades on this bike but for an intermediate level mountain bike everything functioned fine. I plan on keeping the bike components with the exception of breaks until something breaks, then upgrading that component.

    Weaknesses:    I did upgrade my breaks to Avid Juicy 7's within the first year of riding. the Hayes breaks have plenty of stopping power while they lasted but I ran across a problem with hydraulic fluid pushing through the inner membrane of the break line causing a loss in stopping power. O'well. Tires don't last long. Neater do pedals.

    Bottom Line:   
    Overall I would recommend this bike to anyone interested in an intermediate level 29er. I'm 6'3" and ride a 21" frame on mostly xc type trails. Had a blast on this bike last summer and fall and plan on entering a few (amateur) competitive races this spring. Look forward to many rides to come on this bicycle.

    Strengths:    The bike looks great. I just purchased this two weeks ago to replace my 2007 Diamondback Sorrento. I am 6'3" so the LBS set me up with a 21" frame.

    Weaknesses:    The very first trail ride I went on, not even a mile into it, I hit a section of roots while traveling pretty fast. I hit a part that had roots pretty close and I flew over the handle bars. When I got up I realized the high speed Bontrager rim was bent to hell. I had to walk all the way back to my truck and drive to the LBS to get a new rim. After a few rides the brakes are noisy and sound like they are rubbing and the front wheel also has a slight wobble but not to bad it just looks annoying. My front tire also has a slow leak in it so now I need to fix that lol.

    Bottom Line:   
    Overall it is not to bad but I guess I was expecting to much from this bike.
