3 Pawl XDR 12mm End Cap Drive Side Rear

The Bontrager 3 Pawl XDR 12mm End Cap replaces the drive-side end cap on compatible rear hubs, letting riders fit a steel XDR freehub body to select Bontrager Comp wheels. It is a straightforward way to switch drivetrain compatibility without replacing the entire wheel, keeping the original hub and spokes in service for continued use on the road or trail.

Built for a 142mm over-locknut dimension, this end cap accepts a 12mm thru-axle and pairs with Bontrager's 3 pawl internal hub mechanism. It threads onto the driver side of the hub to set bearing preload and support the freehub body, providing a simple replacement part for maintenance or drivetrain conversion on compatible Comp series wheels.
