Strengths:    all the bike, from the geax I put on some Kenda, super 8 2.0 on the rear, and slant six 2.2 in front, now ir really shines on flats, downhill, and going up, and stans arches

Weaknesses:    on real slow sections it gets a little twichy.... but that is it....

Bottom Line:   
it handles as a 26 on the slow stuff, and a 29 evrywere else, I had a 50 K ride, on real hard and rocky ground, really fast riders on hardtails could not keep the pace because of the great suspension action.

Im sure anyone can have lots of fun on this bike...

Strengths:    Lock-out is super, great handling on ascents and decants.

Weaknesses:    Tires, tires, tires. Avid brakes are horrendously poor performers. Chain drop is hard to remedy. Internal routing of rear derailleur cable had to finally be removed and run externally.

Bottom Line:   
'm no one special but I have raced on a Trek since 1987. Glad I could find a bike a this price, with dual suspension and an XC orientation. I am lucky to live in Missoula and ride great trails every night in the Summer. This bikes running gear can't take it. The brakes are absolute crap. Need to be bleed constantly, just plain suck at stopping the bike and should not have been spec'd on a bike that is to be ridden hard daily. They are such a weak link in an otherwise great bike it is surprising. Can't keep the chain on the bike. Shop says, long chain-stays, 3-rings up front and a 10 speed chain and cassette combine into a bike that it is extremely hard not too drop a chain on. If they can't spec a bike over $2k that doesn't stand up to hard daily ridding, I need to look at other brands. Bike itself is fantastic! Running gear is crap! Buy the Superfly AL if you ride any more than each weekend. In 3 months I've already spent enough on service for the brakes, new tires, 3 new chains, a rear derailleur (due to chain falling off and ripping it off) and to have internal routing of rear cable changed out 4 times, to have bought the next model up. Buy the Superfly 100 AL if you ride more than just on weekends.

Strengths:    With some upgrades, you can get this bike into the 23lbs neighborhood pretty quickly and fairly inexpensively. The OCLV frame set (2011) is great. Good geometry, strong, quick, and responsive are just a few adjectives I use to describe the chassis.

Weaknesses:    Some less than desirable components, like the cheap Shimano triple cranks, heavy Bontrager wheels, Sram X9 RD (causes a good bit of chain slap and contributes to some chain suck), and stock Avid brake pads. Change this stuff out ASAP!

Bottom Line:   
I purchased the bike new last spring. It was on sale at the time for about 1/2 retail, allowing me to make considerable upgrades without too much financial pain.

It now rolls on a set of Stan's Arch Ex wheels with Specialized Ground Control 2.3 front and a 2.2 Fast Track rear tires, tubeless, of course! I changed the saddle to a carbon Bontrager; a Bontrager XXX seat post; the handle bars to a Race Face SIXC Carbon Riser bar (30.9); a Thomson X4 stem (90mm), Shimano XT 785 180 2x10 (26/38), Crank Brothers Egg Beaters 3 pedals, Sram X9 Type 2 RD, Sram X9 FD Roller Bearing shifter for 2x10, and Avid Organic brake pads.

I have ridden it about 4-4.5K miles in the past year (excluding winter because of snow). It been reliable and serviceable. I have maintained it well without much out of the ordinary stuff (4 total XT chains, two sets of front rings, 8 sets of brake pads, 5 sets of tires, , new brake lines, cables, cable housing, and one set of fork seals). The one thing to stay on top of are the shock link bushings. They do wear and can cause damage to other parts. Otherwise, it has been a great machine. It has taught me a lot. I know understand what makes a great bike great.

Strengths:    I rode this bike as a demo and I am going to get one- I have always ridden hard tails so I enjoy a bike that climbs well. this bike did not disappoint, this bike climbs great and I found descending great as well. I found I wasn't as fatigued after the ride as I am on my current hard tail.

Weaknesses:    Maybe the Bontrager wheels could be lighter - however this is not a deal breaker.

Bottom Line:   
Great bike! Geometry is great and I found myself going much faster than I have for quite a while at 44 years of age I have been riding MTBs for 15 years.

Strengths:    Light, good looking, fast, great climber, excelent suspension rp2 shock,

Weaknesses:    Tires...

Bottom Line:   
Great, just do not use the geax mezcal, 3 flats in 3 weeks, those tires only work for pavement and hardpack, the rp2 works great, excellent platform, excellent on the open mode, no bob, unless you mash the pedals like a hardtail, had a scalpel good, but this is great, the first time uphill I bear my best time by more 45 seconds, and downhill not so fast because of the crazy tires...

Strengths:    super light, handles well in tough stuff, less fatigue, big wheels compensate for only 100 mm suspension, very light pedal bob in pro-pedal mode climbing or flat smooth when seated, upright riser bar position is good for slow technical stuff but don't feel stretch out enough for high speed descents but im getting use to it

Weaknesses:    tight cockpit, squeaky brakes

Bottom Line:   
I sometimes find my self going much faster than im used to on my old stumpjumper Much easier overall less fatigue

Strengths:    Climbing. Stiff front and rear. Plush suspension. Built-in frame guards. ABP (Advanced Braking Pivot) setup is clean and very flexible. Low center of gravity. Low fatigue factor. Excellent endurance rig. Light weight.

Weaknesses:    Price. Low bottom bracket compared to all mountain bikes, but very reasonable for XC race machine. Limited fork choices (needs G2 offset). OEM fork feels like it needs more travel to balance 110mm of rear shock.

Bottom Line:   
This bike made climbing faster and with less effort. The traction is simply amazing and climbing technical sections is excellent with the low bb and relatively low headset. The bike is so stiff as well, I'm running QR front and rear, but I don't feel any flex. It's an amazing bike and I'm faster than my old hard tail, and just as fast descending as on my Rip9 unless it gets really rough with drop offs, baby head rocks, etc. The ability to change direction on this bike is excellent as well. I really like the G2 geometry. I'm looking to try more travel in the fork as the rear shock is super plush and capable. Although it's a XC bike, I'm slowly turning it into an all mountain rig and it's up to the task.
Excellent bike for those who want to climb fast, ride epics, marathons, etc. and still charge the descents.

Strengths:    Light,stiff,plush,stable,Some good components,and lifetime warr. 29ers are faster in many ways,stable and keep rolling once you get them going.26ers get up to speed faster but are not as stable and don't stay rolling as easily.Light,stiff wheels are a must for a 29er,and they fit larger riders better.

Weaknesses:    Two cracked chainstays,awkward bars,low end crank,chould use remote lockouts or Brain? Needs a 2X10 crank.

Bottom Line:   
Fast bike with many strengths.I think the frame was made to light though.Trek should redesign the chainstay.I'm a 42yr old expert xc racer ,6'1, 175lbs,and ride a lot.I've cracked many frames but two chainstays in 6 months!.I thought Trek would have this rectified by the 2nd year.
Trek comes through with hassle free warranty but still a hassle...

Strengths:    Lightweight but strong and rugged. Those 29ers roll over everything!

Weaknesses:    Haven't found any yet.

Bottom Line:   
This. Bike. ROCKS!

I rode a demo of this exact bike when the Trek Demo tour came to Austin in March 2011 and I knew I had to have one. I saved my pennies and bought myself one as a birthday present in July and I have not been disappointed!

I would recommend this bike for anyone who is an intermediate or advanced rider. I probably wouldn't recommend for a novice rider (unless you plan on doing a lot of basic skill drills using a hard tail as the Superfly 100 compensates TOO well for poor technique, which is NOT what you want when you're just starting out).
