Fuse Expert 6Fattie

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 6Fattie will have you shouting this sentiment from the rooftops.

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 6Fattie will have you shouting this sentiment from the rooftops. Our 6Fattie Wheel 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 Manitou fork with 120mm of smooth travel. This Fuse is equally ready to take a beating and to hand one out to the trail.
  • 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 chainstay that accommodates the 6Fattie wheel/tire combination without compromising on our hallmark short chainstays that provide unrivaled handling and climbing prowess.
  • A Rock Shox Reba RL fork pairs 100/120mm (size-specific) of smooth travel with adjustable rebound for maximum absorbency over harsh terrain and easy, on-the-fly adjustments to the damping to hit the perfect tune.
  • 650bx3.0" 6Fattie Purgatory and Ground Control tires feature a perfectly sized contact patch for life-changing levels of traction and control while cornering, all without sacrificing climbing efficiency or descending prowess. And with a GRID casing protecting the sidewalls, these tires will stand up to anything the trail can throw at them.
