    Strengths:    Wheels, Frame, Brakes, Shock

    Weaknesses:    Rear Derailleur, Grips, Pedals

    Bottom Line:   
    I've had a 2013 Trek Mamba for 4 years now and put countless trail miles on the bike. The trail I ride 2-3 times a week is littered with roots, a few decent drops and a few jumps and the bike has been great. The main items I didn't like were the rear derailleur not being a clutch type and after a few years the front fork failed on a very rocky rough trail which wasn't surprising. I upgraded to a Fox air shock and eventually also upgraded to a 1x setup with a clutch type derailleur and have fallen in love with the bike all over again. This is a perfect beginner bike that can easily be upgraded as things wear and your skill level increases. I think I'm the only person on here that likes the brakes not being so touchy...

    Strengths:    Excellent entry level bike. For the beginner to even intermediate this bike handles well in the corners, climbs and for a heavier bike is a fast ride.

    Weaknesses:    Weight could be a weakness, but then again, it's entry level so why does weight matter and if that bothers you, it can be easily remedied. If you're an advanced rider then sure...this bike's not for you but for the average Joe or for people who enjoy riding bikes....this one really has no weaknesses. It will do what you want it to do and more than likely a bit more.

    Bottom Line:   
    With the OE I put this bike through a very decent amount of abuse and it stood tall. I'm 6'3" and about 205 lbs. So after a year of becoming obsessed with MTB'ing, I've upgraded everything sans headset and fork (those will be next maybe..going to wear out OE first). Now my skills are advancing to another level and I'm loving my Mamba even more. I waited and got a deal on this bike. I was diligent and patient in choosing the upgrades and got deals on all of them.....and yes, I could have just spent the extra coin on a higher end bike......but now, this one is unique to me and is my own. It now weighs around 26.5 lbs and it was originally at least 32+ pounds! I'm not necessarily a weight weenie per say....I just went down the upgrade path which honestly...if you get into a slippery downhill slope LOL. It gets a ton of compliments though and I loved this bike from the beginning even before the upgrades so it's a fantastic bike.

    Strengths:    this is a great bike I have owned this bike for 1 yeah now and I haven't had to put any money into it and it rides like a dream! the brakes sometimes seam to scream sometimes but if u sand down the pads and discs they seam to be fine. I have ridden this bike hard and holds up to my standards, yes I would not use this bike for downhill biking but this bike wasn't made for that it was made for a cross country feel and I have other bikes that do this for me! for the price u cant beat it this is a solid 5 star bike.

    Weaknesses:    stock tires wear fast but good for stock!
    no complaints for this bike.

    Bottom Line:   
    ugh, not much to say. this bike is good for the average person who is mainly on light trails and pavement. the forks are okay. the brakes are okay. everything is okay but nothing pops out in your mind as a great item. if you want to start a project bike then this is a great frame, but everything else is ridiculously heavy and brittle. i broke the petals in the first month (ball bearings exploded) so i got some new ones, the hydraulic brakes are horrible for the first 5 months, the bike rattles so much you need to re tighten all the bolts every time you come to a stop (thats if you can come to a stop) they are so weak. also hydraulic breaks are supposed to be great for all weather. when it rains the breaks lose 70% of their already lackluster stopping power. the fork is decent, if you plan on going off any jumps/drops higher than 12 inches then you will need a stiffer spring which i imagine you can order from rockshox. the whole thing weighs about 40 pounds on a good day. and i have accessories mounted on it so its even worse. i got to choose this bike for my birthday and honestly this is the worst birthday gift i have ever received. i have spent countless hours repairing this bike ( i work at a bike shop and mechanic bikes so its not like i don't know what I'm doing) I wanted a full suspension bike but in the words of the bike seller "you don't need it" ill show him who needs full suspension when i walk in there with a cracked frame and forks split in two. wheres my free 1 year maintenance now huh? its reliable ill give it that, it is constantly there, WAITING FOR ME TO FIX IT. i recently had a run in with a tree, literally. and snapped the rear brake lever. now i know you cant just replace the lever and you have to buy a whole new master cylinder. its a good bike for a kid who is biking to his friends house or to work couple times a week, but if your even thinking about becoming a mountain biker this bike is going to send you in the wrong direction with its weight, squeakiness, lack of stopping power, and over all poor design. i have the gary fisher edition 2013 (for the record) please excuse the spelling mistakes I'm sure i have made, but as long as i got my point through its fine. if you buy this bike, you will regret it.

    Strengths:    Brakes - Control
    Everything not listed in weaknesses

    Weaknesses:    Brakes - Stopping power
    Stock pedals
    Tires - F&R -
    The bike has come out from under me a few times while leaning in hard on road rides.
    The rear end always slides around on me while on sand/dirt/mud.
    Depending on the surface the bike can feel uber squirrelly leaving you to constantly calculate body movement/weight distribution to avoid bailing.

    Bottom Line:   
    Bought this bike in Aug of 2013 for $1099 CND it now has over 900km of mixed trail and road.

    Swapped the pedals for eggbeaters during the first week.

    Will be getting new tires for it once it crests the year mark due to them being the only real downside on my adventure thus far as noted in the weaknesses.

    The Hayes breaks are amazing for control though certainly leave you wanting more stopping power, though it may just be the large amount of lever movement required. It feels like they need the air bled out of them.

    I had done an awfully large amount of research regarding 26ers and components and was looking at a specialized crosstrail when the dude at my LBS showed me the mamba. Rode it around the parking lot, slept on it and bought it the next day with very little research into 29ers.
    I would certainly do it again.

    Strengths:    Big ol' wagon wheels roll over everything, great on hard packed trails, climbs great.

    Weaknesses:    A little heavy, original tires too thin, components are a little cheesy.

    Bottom Line:   
    Great bang for the buck. I have a 26" full suspension Gary Fisher that I normally ride, I bought the Mamba as a spare bike and to ride on the road with my wife (I couldn't bring myself to buy a road bike) and Trek gave me $600 towards a new bike since I broke the swing arm on my old VRX and couldn't get a replacement part. But this season I've been putting the Mamba through the wringer. It's holding up pretty well. It's fast, climbs well and is beefy enough to take a beating. Yeah some of the components are a little cheesy but so far so good. If I continue to ride it regularly I'll probably at least change to a fatter tire and when components start wearing out, upgrade them. All in all it's a pretty fun ride.

    Strengths:    Stability
    Weight - Value

    Weaknesses:    XC32 Rockshox fork
    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.

    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.
