R4 Front Hub

$170

The R4 is designed to be a solid, reliable hub with a durable axle assembly and robust set of bearings.  We're 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. 

We 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 (we use 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!).  R4 front hubs are available with standard or ‘torque’ end caps.

Please select below which type of end caps you need. If in doubt drop us an email. Spare parts can be found here.

hard to mess up

I mean it would be hard to get a front hub wrong, but this does the trick perfectly. No complaints and bearings are super easy to change. Matches the rear too which is nice.
