Trek’s factory cross-country racers have long been 29er evangelists, so it’s no surprise to find Canadian Emily Batty on one at the UCI World Cup round in Windham, New York. Her Trek Superfly isn’t just some off-the-shelf rig, however, as there are a lot of special details that set it apart from the pack.

Batty’s carbon Superfly is light at 9.20kg (20.28lb) but not outrageously so. The 15.5in frame size certainly helps, as does the smattering of flagship gear such as Shimano’s current XTR 2×10 transmission, magnesium-bodied hydraulic disc brakes, and a carbon saddle, seatpost, and handlebar from team sponsor Bontrager. Bontrager also supplies the new XXX TLR Disc 29 wheelset, which uses aluminum rims with a rather Stan’s-like shallow profile for reliable tubeless performance at the very low pressures that Batty prefers.
More weight could have been saved with a different fork choice from team sponsor Fox but Batty prefers the instant response of Fox’s electronically actuated iCD damper. Instead of the standard handlebar remotes that work on a cable and mechanical valve, iCD instead uses an electronic rotary switch that’s quicker and easier to operate on the fly and connected to a fast-acting servo motor in the damper. Power comes from a rechargeable lithium-ion battery tucked inside the steerer tube.

Full team mechanic support brings with it a bike that’s perpetually in perfect tune and Batty’s Superfly was literally lemony fresh during the photo shoot thanks to a fresh coat of polish. In addition, though, are several neat tricks that heighten the tune even further.
Instead of the standard quick-release front and rear thru-axles, for example, Batty’s bike is equipped with bolt-on axles from Fox and FRM to save weight. Team mechanics even hand file the aluminum non-driveside dropout flange to produce a better interface for the FRM axle’s flat head.

Meanwhile, a small pad is zip-tied inside the front derailleur cage to reduce chain noise on bumpy terrain and the unused bottom-pull cable arm is sawed off. Team mechanic Matt Opperman even omits the pad retaining pin safety clips and bleed port covers from the XTR disc brake calipers, and the rubber hose nut covers on the brake levers, saying they just add needless weight and hassle, anyway.
Standing at 1.61m (5ft 3in) tall, Batty does have to make some adjustments to get the faster-rolling big wheels to fit underneath her. Out back, the saddle is pushed way forward on the rails and the seatpost is also flipped around to produce a +5mm setback. Up front, Bontrager has actually gone so far as to custom machine a 100mm-long stem with a -25° angle. According to Opperman, Bontrager’s Race-level stem would have also done the job in terms of fit but these are significantly lighter and apparently also noticeably stiffer given their big, rectangular cross-sections. Production versions are supposedly going to be released soon.

Tire and suspension setup is about what one would expect from a top-level cross-country racer. Opperman said that Batty would run a slightly higher-than-usual (but still low) 21-22 psi to tackle the rocky Windham course but fork pressure is somewhat high at 72psi given her slight 48kg (106lb) weight.
Either way, Batty is coming off of a strong performance at the Commonwealth Games so another good showing here in Windham is a safe bet.
