Industry Nine Fuse Carbon System Hydra2 29" Wheel Carbon That Eats What E-Bikes Dish Out E-bike riders putting serious miles on technical terrain need a wheel that was conceived for those loads, not retrofitted to handle them. The Fuse Carbon started as an e-bike-specific design and carries that through every layer of its construction. A wide 33mm internal carbon rim gives high-volume aggressive tires the casing support they need on rough, chunky lines, and the Hydra2 hub paired with System Spokes turns this into a complete, fully integrated build. The System Spoke eliminates the j-bend and nipple entirely, threading directly into the hub shell for a connection with no stress risers and no flex at the joint. When you drop the power on a technical climb or charge into a rock garden, the Hydra2 hub picks up drive in 0. 41 degrees and puts it to the ground without hesitation. Features Carbon rim with 33mm internal width supports high-volume enduro and e-bike tires with the casing stability needed on aggressive terrain Hydra2 hub with 870 points of engagement at 0. 41deg near-instant power transfer engineered specifically for heavy trail, enduro, and e-bike loads System Spoke in machined 7075-T651 aluminum direct-thread design with no j-bend and no nipple eliminates stress risers for a stronger, flex-free connection Boost axle spacing 110x15mm front and 148x12mm rear for optimized stiffness and spoke bracing angle SPECIFICATIONSWheel Size29"Rim Material Carbon Inner Width33mm Spoke Drilling28h / 32h Valve Type Presta Tubeless Yes Tire Type Tubeless, Clincher Brake Compatibility Centerlock Front Axle110x15mm Boost Rear Axle148x12mm Boost Intended Use Enduro, All-Mountain | Industry Nine | Fuse Carbon System Hydra2 29" Wheel Front, 15X110Mm Boost, 6-Bolt
