Strengths:    Fast (no Strava but I can tell), light (I believe I'm at 25lbs with Crank Bros. candy 3 pedals on.) Supple suspension climbing in "trail" and descending in "descend", has the obvious good 29er traits of rolling over ruts and rocks, carves and is lively even though others have said a longer chainstay should prohibit this, quick side to side, wants to be railed, asking to drift ... I'm still working on this part! balanced geometry, great for xc and trail riding, excellent components, fox Fit (though I seem to recall Trek spec does not mention Fit) fork, 15mm, 142x12 ABP rear thru axle (actually the axle that came with the bike was overtightened at the shop and a machine screw at the end sheered off, broke...they gave me a supposedly beefier ABP Maxle that typically goes with a Remedy, probably heavier, hopefully not liable to break when cinched down!), all XT, Bonty parts look excellent to me but what do I know, asymmetrical rims and spoke placement to equalize dish on both rear (cassette) and front (rotor), bonty rear hub with dt swiss "internals"?, xt not carbon cranks, all internal cable routing, 3 (4?) insert points...I use 2 derailleurs and 1 rear brake but rear brake has bosses external so you could use the (rear brake) port for internal dropper if you wanted. Port for shock if desired, check it out. Alloy chainstay not carbon (may actually be a "strength"), CTD that actually makes a difference when changed. Haven't used "C" yet...pretty much locked out at fork and totally locked out at rear shock...I'm not racing! T and D work beautifully set pressure you like...probably higher pressure than Trek recommends but mechanic said I could set to suit myself w/o harming the fork/shock. I even like the saddle so far! Ice tech rotors...whatever, they seem to work so far. XT brakes well proven, excellent. Carbon flat bar. Even grips are good. 2x10 I like it...glad I didn't go for XX1...I don't think I'm that strong & I think better to have small shift increments.

Weaknesses:    Tires were ditched for Schwalbe front 2.35 nobby nic and rear 2.25 rocket ron. These seem excellent so far but rear is taking a couple days to seal up tubeless (I think this is pretty normal). I think these are really trail riding tires. Has obvious acceleration disadvantages compared to 26er sized wheels. From what I've heard, you can always buy a 2K carbon wheelset...stiffer, lighter rotating mass, better ride quality, really?

Bottom Line:   
Well, I covered just about everything already. Cable routing (seems to me) is awesome and really makes an already beautiful frame design, STUNNING, in my opinion. I know, who cares what it looks like...right? ABP...I can't tell you if it works or not but it certainly is an elegant design. front derailleur direct mount (I think it's called) also a well thought out design. I am 53 years old, 5-10 (-) and got the 19 inch frame (I had demoed this bike previously and recall that one was labeled 18.5" ... but I think the frame designations changed. Anyway, I'd say the 19" frame fits really well, I doubt I could have gone down to a 17 (17.5"?) frame. I am still able to "row" uphill on this bike and can still get behind the saddle when I want to for descending. I moved the saddle up less than 1 cm and shorted the 100 mm stem to 90 mm. 90 mm stem (with 7 degree rise up) is pushed fully down (not sure exactly if it belongs on the conical headset cap but mechanic will advise when I take it in to cut steerer down). Seems to feel really good right now. Comparing to my 26ers with stems higher on steerer, I felt I needed to push stem all the way down. Must be a 29er thing. Oh, right, tapered steerer (I think) see Trek spec. for this and other specs I missed. OK I must admit I've only ridden it 3 times in this first week and I'm still learning the feel for the ride. Certainly need to adjust gears and suspension while you still have is usually charging through transitions so fast it's easier to forget what gear/setting you want. Oh, and very's QUIET. Rear derailleur has clutch which I think contributes to this. I'm hoping linkages and frame remain quiet. Today, conquered a fairly short, very steep, climb I haven't been able to bust out in a while...could also be I'm on a diet which really helps! Anyway, this is a very expensive bike so it should be really good! So far, I'm impressed. O.K.!!! Hope that helps! I think I can somehow be contacted on MTBR if you want to ask me anything else. Thanks!

Purchased At:   Jax in Fullerton, CA

Similar Products Used:   Demoed Niner Jet 9 (dirt), rode Niner Jet 9 rdo (pavement only)'s steeper up front I think, quiet, seems like it could be fast and stiff but noticed same minor flex than the superfly 100 elite sl has. I believe wheels on either bikes contribute significantly to this, SC Tallboy LTC (is that what it's called?)...I owned blur LT previously...not a big fan of digs in well but not just not wild about ride quality, Giant anthem 29er alloy...uninspiring, Scott, Specialized (10K) demo epic. Fast up but hand numbing down...could have been fork was set wrong. Also, I don't really like the whole brain concept, too complicated and takes away the ability to hop, it seems. I totally get why racers win on this bike however.

Bike Setup:   See above. Sorry I'm out of order here. My current 26ers are Stumpy fsr expert 26er (2006) with interrupted seat tube, excellent bike for trail...Titus racer x Ti which is more xc oriented, Cannondale rize 4, 140mm fork 130? mm shock, big tires very plush suspension and probably not real efficient but very fun. Old SC superlight, etc. Anyway the Trek superfly 100 is my first 29er...I was looking for a fast climber full suspension fire road bike because that's mostly what we have where I live (Corona del Mar, CA). It's awesome!

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:    Main reason to buy - Great frame and suspension action. Rides great and handles tight single track easily. I am 190 lbs and the bike has no noticeable flex in the back or front end. For the price the components are good and reliable.

Weaknesses:    Wheels and cassette are very heavy. The X7 components are ok but heavy with the triple crank.
Stock Bontrager wheel set required truing after first ride.
Should come with 2x10 and full X9 from the factory

Bottom Line:   
This is my first 29er and does ride different from my last 26er. Took a few rides to change my corning style to fit the bigger wheels.

The bike as built up, see below, rides very fast and handles very good. Suspension was easy to dial in and feels light and lively. Fit and finish is very good and the Bontrager seatpost, stem and handle bars are light right out of the box, even if they are not the sexiest parts out there. The Avid brakes are strong and modulate well, pads do squeal. I took a fine file to them after a few uses and this quieted them down a good deal.

Build up, I bought the SL over the 100 Elite SL for the price difference knowing I would upgrade the wheels, cassette and to a full SRAM X9 2x10 drive train. Converting the wheels, cassette and drive train saved 2.3lbs, bringing the bike very close to the Elite SL weight and overall price was still below the Elite SL after selling the X7 shifters, front derailleur, and triple crank on eBay plus I have a spare wheel set. Bike now weighs a reasonable 24.3 lbs and finished price is just a tad over $4600.00.

The biggest change came with changing wheels, the stock wheels are heavy and you feel it spinning up and coming out of corners. At minimum, change wheels when you can with something lighter, it really brings the bike alive.

Strengths:    ~Lighter than most 4" travel 26er FS frames
~Awesome geometry
~51mm offset fork decreases trail, while mitigating increased slack
~ABP rear pivot is beefy and super stiff
~Plush, 4.33" (110mm) of rear travel
~Asymmetrical chainstays
~Thick downtube and BB equals 100% forward thrust
~Carbon frame armor
~Equally great climber descender
~Stock Bontrager saddle is actually nice
~Rock Shox fork with dual air simply rocks

Weaknesses:    ~Dated, 2010 tech on front derailleur mount(direct mount/type 2) adds grams
~Full-length cable housing for front shifter does not optimize correct cable pull ratio
~"Big Sweep" bars feels like a Beach Cruiser
~Bontrager RXL 29er wheelset weighs a whopping 2000grams
~SRAM XX brakes is unsafe, loud and unreliable - ditch them
~Rear Fox shock with Kashima coating is high-maintenance

Bottom Line:   
Since MTBR did not designate review space for my 2012 Trek Superfly 100 Pro - I am reviewing it here, as the 2011 SF100 Elite was the equivalent model, for that previous year:

After the 2010 Gary Fissure Superfly 100 frames were deemed a complete reliability nightmare - Trek corrected everything for 2011/2012, by reinforcing unidirectional carbon layups in all affected areas, without compromising weight. Trek also mandated 142x12 rear axles, further beefing up rear stiffness and stability. The ABP rear pivot works as claimed, greatly minimizing tire skidding and keeps the suspension fully active under hard braking.

Overall - the 2012 SF100 Pro is a dream on two wheels; it climbs almost telepathically. Baby head rock gardens suddenly turn into frozen peas and carrots, allowing you to confidently blaze through them like a 7" travel Freeride bike would. Thanks to the short wheelbase - it executes tight switchbacks like a 26er does. Everything about this bike screams SPEED. I've ridden the BEST of the BEST 29ers out there and this bike still has the most balanced of all trail attributes, combined with workable light weight.

It's still not perfect - but damn near close....

Strengths:    Light weight. Incredible handling. Amazing acceleration. Nice ride, versatile with the CTD fork and shock. Descends amazingly well for a race bike. The 29er wheels go over stuff my 26" bike had trouble with. Really good looking. Well spec'd for the price

Weaknesses:    My skills compared to the bike's abilities! Black is hard to keep clean.

Bottom Line:   
Bought this as my all around trail bike and to race occasionally. Coming off 26" Giant Trance X with 5" of travel which rode nice and decended very well. Superfly descends just as well as Trance but climbs better. Incredibly stable. I am clearing technical stuff up and down that I could not clear on the Trance. I switched out the 29-1 tires for 29-3 Experts and made them tubeless before my first ride so I can't comment on the stock tires. Gearing is perfect. Love the 2X10. Was worried that the top gear would not be enough, but that hasn't been a problem. Also worried that the 26 tooth small ring might be too big for steep climbs, but that hasn't been a problem either. Black hard to keep clean. I don't do big jumps or drops, but I do like to go fast both up and downhill. No problem with this bike. Got $1,000 off at Westlake Bike Shop. Good service and store.

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:    Overal feel of the bike, it really translates every pedal stroke directly to the wheels.
The QR15 front setup really stiffens up the front
Suspension has got a nice balance between performance and comfort, after setting it up to my weight and wishes don't feel the need to use the climb (lock) position. Also uphill doesn't feel like it is absorbing pedal power but feels like it is generating traction

Weaknesses:    Delivery time, the 2013 bike took quite a long time to finally show up
Non TLR rims, Ok the RL wheels are Tubeless ready, but you need the Bontrager rimstrip to ride tubeless. This rimstrip is not standard installed, Looks like the Trek accountant thought it was to much to for a 5200€ (retail here in Netherlands) bike
In comparison to it's competitors the bike is a bit more expensive, Trek could have improved on the specs, throw in a kashima coat or at least supply a carbon seatpost

Bottom Line:   
I was looking to replace my Sugar 29er bike. I was looking for a bike equiped with Shimano XT components, 100mm suspension and a carbon frame. Based on my experience with the Fuel 98 and Sugar 292 the full carbon frame bike feels much faster and responsive.
After looking at it's competitors and having a go on the 2012 sf100 and experience with the Trek brand. I decided to place an order for the 2013 SF100 elite. Also the discount from my LBS helped to decide in favor of the Trek. Looking forward to take the bike to ride the marathons this season.

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.

Strengths:    This bike is not doubt a very nice ride. Its smooth stiff and fill like your riding big sort of speak. Like comparing riding down a dirt road with a SUV instead of a honda accord. The bike is fast and very well built.

Weaknesses:    The Bontrager complaints are somewhat true. Not so much for the stem, handle bars and seat post. The weakness is the wheels... they are not horrible but definitely don't belong on this class of a bike. It should have come with the RXL wheels from Bontrager to match the other Bontrager parts for sure. Complete Shimano XT components are a huge upgrade from the 2011 models. Chain slap is a slight issue with this bike. The full suspension gives the rider more confidence. The impact is often more than what the rider feels. As a result....... chain slap! Shimano XTR or new XT Shadow Plus rear derailer def needed. The bike is not all that light compared to other carbon bikes. For a full suspension bike it is still light weight. Trek's 2013 models are lighter and compare a lot better to other bikes in it's class, regarding weight.

Bottom Line:   
Get it if looking it! Can't really go wrong. There are always going to be upgrade. Thats how these companies made money. For an everyday rider or even occasional racer, this bike is very nice and almost in a class of its own.

The review is for the 2011 model, this bike flat out rips!!! I race mostly sport XC events and this bike never disappointed. Light, smooth shifting and very stable. I was very impressed how well the ABP rear axle really worked. The G2 geometry lets you carve single track like butter. I would run the pressure a little higher in the rear shock for short track racing and lower for trail riding. The really beauty of this bike is its really an all-round do everything bike. Longer rides this bike cruises smoother than a Cadillac. The specs on this bike are great, actually better then the 2012 version by a long shot. Bontrager rims are good but unfortunately not the lightest. The stock tires are also more trail specific, the only part i needed to swap out. Frame is super stiff and and gorgeous! Rode the aluminum SF 100 and the Carbon Elite feels worlds apart in every category. Trek hit a home run here, no wonder its there most popular bike.

Date Reviewed: May 19, 2012

Strengths:    The Superfly 100 really shines in technical terrain and flat out pedaling. The 2x10 drivetrain just works; the right gear is always there. The addition of the QR 15 fork and the Maxle 142x12 rear end on the 2012 model is a nice touch and gives me more confidence in the bike's overal capabilities.

Weaknesses:    The stock tires aren't great for wet conditions, but in medium and dry conditions they hook up, roll fast, and corner very well.

Out of the box the Shimano XT Shifters were set for a 3x10, and it took me a few rides to realize that I needed to change the front shifter over to the 2x10 setting and adjust everything accordingly. Once that was sorted, the chain rubbing issues I had with the front derailleur were completely gone. I also believe that Trek should have included the Shimano iSpec brackets for the shifters because the bike is equipped with full the XT line. A small, but nice refinement.

Trek's suspension calculator seemed a bit off as I couldn't get anywhere near recommended sag with the recommended air pressure (roughly rider weight plus 10 percent). Pressure matching body weight seems to be about perfect and I haven't bottomed out.

The stock bar width is also a bit light at 690mm. 720mm would have been greatly appreciated on my 23" frame.

The Fox suspension is all non-Kashima. A small detail, but important considering they are all at the "Factory" level of Fox's line.

Bottom Line:   
I bought the Trek Superfly 100 Elite to be my endurance racing rig for the 2012 (and beyond) season. However, now that I have it, I can't put it down. My biggest concerns with the bike were that the 29 inch wheels wouldn't be that fun on the tighter, more technical trails in the Pacific Northwest. However, I feel that the bike actually handles tight, technical XC better than my 26 inch bikes do. It seems as though the G2 geometry with the short stays, long top tube, and custom offset Fox Fork, is completely dialed in for my 6'5" self.

This is also my first time working with the Shimano 2x10 drivetrain, which is a huge improvement over previous generations of XT. I also feel that it is a huge improvement over the 3x10 system that is offered concurrently in Shimano's line. The shifts are solid and precise like my former favorite SRAM X9 systems, and you can drop two gears in one swipe on the rear. Not only can you drop two on the rear, but the release is instant instead of on the rebound as was the case with previous systems. Faster, more precise shifts are always welcome.

Once I had the suspension dialed in using and then modifying the settings suggested by Trek's suspension calculator, the bike really came alive. On flat ground the bike feels efficient and fast, taking everything you can give it to go faster. On technical trails the bike eats terrain, flows well, and feels lively enough to take to the air quite easily. Because the bike uses its 110mm of rear travel and 100mm of front travel so well, it feels capable of much bigger and faster things.

The bike's cockpit is made up of Bontrager bits and pieces. All of which work very well, look refined, and keep the weight down. The handlebar looks slightly goofy out of the box as its sweep is a bit more than others, but after riding it for a few weeks it really does feel very natural. I just wish the stock bar was a bit wider for my broad shoulders.

My 23" weighed in at 26 pounds out of the box with pedals (Crank Brothers Candy in blue). While the bike almost looked like it had too much blue out of the box, once it was outside it just looked perfect. Changes I've made since getting the bike include adding Bontrager's tubeless kit, Shimano's iSpec adapters, and a Bontrager RXL bottle cage. The bike sits now at 25.5 pounds.

Would I purchase this bike again? Yes, in a heartbeat. The bike is fun. Pure fun. I have to keep reminding myself that the bike is a cross country bike and not something bigger.

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.
