What Our Gearhead(R) Experts Are Saying:"I've ridden both the front and rear on an XC setup and the acceleration feels instant. The engagement is quick, and the rims strike a nice balance between stiffness and comfort on rough courses."When race pace sets in and every second matters, we rely on a wheelset that responds without hesitation. The KFX i28 Boost Wheel from Full Speed Ahead is built for fast, technical XC riding, where efficiency, traction, and control all play a role in staying ahead of the pack. The carbon rims use an asymmetric, variable height profile to balance strength with vertical compliance, smoothing out chatter while maintaining precise handling. A 28mm internal width supports modern tire shapes for better traction and stability, while the tubeless-ready, hookless design allows us to run lower pressures with confidence. PRS hubs deliver fast engagement for immediate power transfer, and the hand-built construction ensures consistency across every ride. Whether we're running the front, rear, or full setup, it's a system designed to move quickly and hold lines through demanding terrain.
