Industry Nine Fuse Carbon Classic Hydra2 29" Wheel Carbon and Carbon Only Riders on older frames with non-Boost spacing don't have to settle for a lesser wheel. The Fuse Carbon pairs a hookless carbon rim with the Hydra2 hub - the same engagement system used in some of the most demanding enduro and e-MTB builds out there. At 33mm internal, the rim puts a wide, supportive platform under high-volume tires, keeping the casing square on hard cornering and absorbing square-edged hits with less deflection. The Hydra2's 870-point, 0. 41-degree engagement means the wheel is driving the bike the instant you put power down, no matter how technical the transition. It's a serious upgrade for aggressive trail and enduro riders who haven't moved to Boost spacing yet. Features Hookless carbon rim, 33mm internal width supports high-volume tires up to 2. 8" and keeps casing shape stable under load Hydra2 hub with 870 P. O.
