Bontrager Rapid Drive 54 Rear Hub 142x12mm

Fast, reliable engagement for every trail. The Bontrager Rapid Drive 54 Rear Hub delivers 54 points of engagement — just 6.7 degrees of rotation before power transfer begins — so your pedal strokes connect immediately and precisely, whether you're sprinting out of a corner or clipping in on a technical climb.

The alloy hub shell is built tough for the demands of mountain riding, while the straightforward cartridge bearing design makes servicing accessible for home mechanics and workshop alike. Compatible with Shimano and SRAM HG cassette bodies, it integrates cleanly into a wide range of standard thru-axle mountain bike builds.
