Fuse Expert 6Fattie/29
Technical Specifications

We said it once, and we'll say it again—more volume means more speed. It might be a claim that sounds flipped on its head, but one ride on the Fuse Expert will have you shouting this sentiment from the rooftops.

Our 6Fattie Wheel/Tire System puts out more traction, more floatation, and better handling without sacrificing anything to efficiency on climbs. And to solidify itself as a proper trail machine, this Expert iteration of the Fuse places a focus on blending durability with performance. To do so, we spec'd it with strong alloy rims, a bulletproof one-by drivetrain with plenty of hammering and climbing ability, and a plush RockShox Reba RL fork with 120mm of smooth travel. This Fuse is equally ready to take a beating and to hand one out to the trail. We also designed this frame to allow you the opportunity to toggle between 29-inch wheels (not included) and 6Fattie wheels, allowing the ultimate in configuration options for the trail at hand.

  • M4 Premium Aluminum proved to be the right material for the job, allowing a lightweight, durable frame with a low and slack geometry that's equal parts snappy and efficient on climbs and descents. It also allowed us to incorporate our exclusive Diamond Stay that accommodates the 6Fattie wheels/ tires without compromising on our hallmark short chainstays that provide unrivaled handling and climbing prowess.
  • A RockShox Reba RL fork handles suspension up front with ease, soaking up bumpy terrain with its 120mm of plush travel.
  • SRAM's 11-speed GX groupset features a wide gear range that delivers climbing and descending efficiency in spades. On top of this, the one-by setup is notorious for being next to impossible to drop a chain with, plus it provides a significant weight savings in comparison to a standard two-by setup.
