Fuse Hydra2 System Boost 29in Carbon Wheel

The Fuse Hydra2 Boost 29in Carbon Wheel runs a 33mm internal width on a reinforced WR1 layup, sized to resist the added torque and battery mass an E-bike motor puts through the rim on every hard restart. The Hydra2 hub's 0.41-degree engagement window means motor-assisted power reaches the tire almost as fast as it's delivered. This build pairs that hub with Industry Nine's proprietary alloy System spoke, built specifically around the Hydra2 System platform rather than a standard J-bend layup.

What Our Gearhead® Experts Are Saying:

"A 0.41-degree engagement window means the hub loads up almost instantly when a mid-drive kicks in, and I haven't felt that translate into flex anywhere in the rim after stacking hard technical descents onto full-charge motor runs."
