Bontrager Rapid Drive Fat Bike Hub

The Rapid Drive 108 system provides 108 points of engagement, meaning your drivetrain engages almost instantly when you start pedaling. This minimizes dead space in the crank rotation, which is particularly helpful for technical climbing or navigating tricky, low-speed terrain on a fat bike.

The rear hub comes stock with a SRAM XD driver, which is specific to SRAM cassettes. However, Bontrager offers additional freehub bodies for this model, so you can swap it out to accommodate Shimano or other drivetrain standards if needed.

These hubs are designed for standard fat bike spacing: 150x15mm for the front and 197x12mm for the rear. Please verify your frame and fork measurements before purchasing to ensure compatibility with these axle standards.

No, these hubs are built specifically for 6-bolt disc rotors. You will need to ensure your brake rotors are compatible with the 6-bolt mounting standard.

These hubs are drilled for 32 spokes. You will need to select 32-hole rims and spokes of the appropriate length for your specific rim and lacing pattern.
