Trek Superfly Elite 29er – First ride review

We're only just starting our testing on Trek's new Superfly Elite 29" carbon hardtail. So far it's fast and agile but could use a bit more cush out back

BikeRadar verdict

80.0 out of 5 stars

"Sharper and leaner than its predecessor but designed for race speed, not long-ride comfort"

Trek were among the earliest proponents of carbon 29in-wheeled hardtails and their latest Superfly Elite 29er gets a wholly revamped frame for 2011. Our test period has only just begun but it's already evident that this new version is sharper and leaner than its forebear.

Ride & handling: Stiffer chassis delivers quick moves but a stiff ride, too

The Superfly's standout feature is its brilliant handling, courtesy of the Trek-exclusive G2 fork crown and its increased offset that produces trail figures similar to those of a standard 26in-wheeled bike. While other 29er frames can produce good handling characteristics via slightly steeper head tube angles or by simply having ultra-stiff, flex-free front ends, the Superfly tackles the root of the issue and feels 'normal' with little to no adjustment period required.

High-speed stability is rock-solid, as you'd expect from a two-niner, but it's the low-speed stuff where the G2 design really shines. There's nary a hint of wheel flop and when the usefully wide Bontrager Big Sweep carbon bar with 12 degrees of rearward bend and the short 90mm stem are added in, even tight corners are reduced to a simple matter of point-and-shoot as long as there's enough room for the 1,116mm wheelbase. 

The newly puffed-up frame further bolsters that intelligent geometry as there's now a greater sense of solidity. It's especially noticeable when you're bombing through sketchy terrain or muscling the bike out of the saddle as there's little front-end twang to pop you off your line. The 20mm front travel bump to 100mm augments the bike's abilities on a wide selection of terrain, too. That added chassis rigidity also helps counteract the negative effects of the bigger wheels – namely their extra mass and inertia.

While they'll never feel as quick to spin up as a feathery set of 26in hoops, the Superfly at least does a good job of the additional heft with its direct power delivery, all while still offering the same benefits – the ability to roll through and over obstacles with greater ease, the enhanced stability in technical terrain and the improved drive and cornering tracition. In general, this latest iteration is less twangy and springy than last year's version and definitely more of a honed cross-country racer.

Ride quality leaves a bit to be desired, though, as while the Superfly is stiff everywhere it should be, it's stiffer than we'd like it to be elsewhere. Trek's frame designers have specified a skinny 27.2mm seatpost to help lend a bit of cushion to the rider's back end but that's only useful when seated and it's plainly evident that there isn't much movement inherent to the frame itself. This doesn't detract from the bike's thoroughbred capabilities but it does give us a bit of pause for multi-hour trail days and upcoming enduro events planned for later this season.

Frame & equipment: Borrowed road tech and a high-performance, no-nonsense build

The new Superfly carbon frame borrows a few key features from other items in the Trek corporate design bag, namely the tapered 1-1/8 to 1-1/2in tapered front end and 95mm-wide integrated bottom bracket shell – both with molded-in bearing seats that eliminate the redundancy of aluminum collars and sleeves. Trek have also subbed in sleeker carbon fiber dropouts in place of the old alloy units, though the faces are still protected by slim bolt-on aluminum plates that protect against aggressively knurled hub end caps. 

Down below, a glued-on Carbon Armor rubber cap protects the down tube and bottom bracket area from rock strikes so there's at least some assurance that this thing will withstand some abuse. Much has been written about whether shorter riders can fit on 29in bikes and Trek deserve some major kudos here. Despite the bump to 100mm of travel up front, they still manage to include a 15.5in size in the range and keep head tube lengths admirably short to help yield suitable bar heights. If you need more proof, consider that team rider Willow Koerber seems to manage just fine at a height of just 1.57m (5ft 2in).

Naturally, Trek's in-house Bontrager division supply as much equipment as possible, including the Race X Lite FCC Scandium Disc 29 wheelset and matching tires, the aforementioned carbon bar and forged aluminum stem, as well as the comfy Evoke saddle and carbon-wrapped Race X Lite ACC seatpost. As we've already mentioned, the seatpost doesn't flex as much as we'd like on a hardtail like this but otherwise the rest of the bits are showing lots of promise.

The wheels are a noticeable improvement over some older 29in Bontrager hoops we've sampled, what with their taller flanges and modest bump in lateral stiffness. The swept-back Big Sweep is easy on the hands and provides much-welcome leverage over typical cross-country bars, and the Evoke saddle is supportive and comfy. The lightweight Bontrager Race X Lite foam grips, on the other hand, may be extremely light but they tend to spin on the bars and they're not all that comfy. If foam grips are a must-have, ESI's silicone foam rubber jobbies are still the way to go (and coincidentally, what the team use, too).

The jury's still out on the Bontrager tires. Subaru-Trek's team mechanic was kind enough to expertly build our bike before we picked it up and subbed in a set of Bontrager XR3 tires – his personal choice for local Colorado conditions. The open tread and meaty knobs grip pretty well on both loose terrain and hardpack and they're light at a claimed 545g apiece but the casings are rather stiff and small (despite their 2.1in marking), and they're not the fastest rolling on harder surfaces, either. 

On the other hand, the SRAM X0 group has been faultless for the first few rides. Shift quality has been on par with the much more expensive XX but with a firmer and more familiar lever feel, and the corresponding hydraulic disc brakes offer excellent lever feel along with easily controllable power. Truvativ's Gutter-equipped GXP bottom bracket bearings seem much improved over older versions as well, with far less initial drag.

Despite the two-piece construction, the carbon-and-alloy cranks are rock solid and, thus far, creak-free. Gearing is spot-on for the bigger wheels, too, with direct-mount 26/39T rings and a 12-36T 10-speed cassette. Total weight for our tester as pictured is just 10.11kg (22.29lb, without pedals) – 400g (0.88lb) heavier than the Scott Scale 29 RC we just wrapped up but more than US$2,000 cheaper at $4,729.99.

Stay tuned for a more thorough long-term report once the local trails are in more consistently rideable condition but we're very impressed with Trek's latest big-wheeled racer so far.

Trek opts for fairly oversized chain- and seat stays on the revised superfly and while it makes for a snappy rear end, it also doesn't deliver as much comfort as we'd hoped: trek opts for fairly oversized chain- and seat stays on the revised superfly and while it makes for a snappy rear end, it also doesn't deliver as much comfort as we'd hoped
