Chromag R4 MTB Hub Item # 1378113
Description
The R4 is designed to be a solid, reliable hub with a durable axle assembly and robust set of bearings. Using a tried and tested 4-pawl arrangement with 36 points of simultaneous engagement. What sets it apart is the large radius that the pawls are positioned on, reducing leverage at the point of engagement.
Chromag opted for a Chromoly steel axle for stiffness and longevity. Using steel allows a smaller diameter axle which in turn gives us more room to use larger, sealed bearings (USA made enduro bearings). The rear axle assembly uses thread-on end caps which are easy to service and resist compression from the frames axle (they don't fall off during trailside repairs either!).
