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 all-new 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 that accommodates the 6Fattie wheels/ tires without compromising on our hallmark short chainstays that provide unrivaled handling and climbing prowess.
A Manitou Magnum Comp 650+ 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.
Custom WTB Scraper i45 wheelset has a fat 45mm width and alloy construction for the perfect blend of speed and strength, which means that you'll experience less deflection, increased traction, and more stability—all at lower tire pressures.
650bx3.0" 6Fattie 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.
Our Stout XC Pro crankset would be the perfect complement to any one-by drivetrain, but here, its strong alloy construction makes it ideal for power transfer on climbs and the inevitable rock-strike when descending through technical gardens.
