FeaturesGary Fisher Collection Innovative bikes imagined by Gary Fisher, built by Trek. More momentum - 29 Inch Wheels A bigger wheel holds its momentum better. So you stay rolling over rough stuff and maintain your speed through the corners. Alpha Platinum: Best Our high-performance lightweight aluminum alloy is continuously cold extruded and butted at multiple points for ultimate weight reduction and superior strength. Frames built with Alpha Platinum feature a high degree of hydroforming to create the most complex industrial designs for the lightest weight, and are finished using Trek's smooth-weld finishing process. You choose, with ABP Convert ABP Convert offers all the benefits of our original ABP, and comes with interchangeable wheel interface options so you can swap from a 142x12mm rear wheel back to a traditional style 135x5mm wheel. 135x5 rear wheel Traditional-width rear hub attaches to the frame using a standard or ABP-specific skewer Can't control big hits? We solved that. Most full suspension air-shock bikes use a small-volume canister. A small-volume shock is efficient, because it doesn't move up and down excessively when you pedal. But it doesn't have the best big-hit control. To compensate, some companies use a less-efficient larger-volume shock. Others try to strike a balance with cumbersome manual controls or with fussy, overly complex shock systems. So to gain control, you either lose efficiency, or you lose simplicity. DRCV shocks solve that.DRCV seamlessly adjusts its air volume based on the size bump you encounter. You get supple feel on the small bumps, seamless control over midsize bumps and harsh hits, with less rear-wheel hang-up. Seemingly bottomless travel on the rough stuff. Big hits seem to disappear. All this, with the pedaling efficiency of a small-volume shock. Small Bumps: DRCV is supple and controlled like any other Fox RP2 or RP23 rear shock at sag and over small bumps. Midsize bumps: This is where DRCV shines. At 50% of compression, the shock opens up more air volume. Where other shocks wallow and stick, DRCV offers seamless control through the nastiest terrain you can find. Finish: Throughout the final stages of compression, DRCV behaves like a larger- volume air shock. Return: As the shock returns to its idle state, the shock closes the secondary air chamber to return to its small-bump compliance. Slow-handling 29ers? Gary solved that. The many advantages of bigger wheels can come with a price: sleepy handling. Gary solved that, with G2. G2 Geometry is our system-wide solution to slow 29er handling. We've optimized frame geometry and fork geometry in tandem to create a bike that handles nimbly in tight, twisty singletrack without compromising high-speed stability. It's why our Fisher Collection 29ers handle better than any others. 29ers don't fit? We solved that. Many Trek models feature a wider range of sizes than the industry standard, to give a better fit to more riders. 29er too flexy? We solved that. Bigger is better. Oversized hub, flanges, and end caps create a flex-free 29" wheel capable of chewing through technical terrain, for more confidence in rough stuff and in the corners. 15QR A 15mm front thru axle makes steering more precise for more control, and the quick release feature allows for easy wheel removal. Robust = heavy? We solved that. E2 is the evolution of the traditional 1-1/8" headset to a tapered head tube, fork, and headset system. E2 tapers from a 1.5" lower to a 1-1/8" upper headset to provide more material where it matters most, resulting in a stronger, lighter frame with point-and-shoot control. Press-fit bottom bracket Press-fit BB is a bottom bracket shell that allows the bearings to press into the frame rather than thread in like standard bottom brackets. This provides a wider stance for the frame’s tubing juncture, resulting in a stronger frame. This wider stance also simulates benefits of an OCLV Carbon-only technology, BB95. 3x10 With a 10-speed cassette and a 3-ring crankset, 3x10 delivers a closer-ratio drivetrain, a wider range of gears, and increased efficiency and durability. Magnesium swing link Minimizes material and weight while maintaining a strong bracing angle for a more rigid frame.
