XMR Rear


SKU: xmrrr
Clear Options


Our XMR (Cross/Mountain/Road) hubs are designed around the ISO 6-bolt rotor mounting interface as opposed to the Center Lock mounting standard used on our CLD hub.  The 6-bolt system requires a slightly larger flange diameter which allows for a classic look with machined “windows” in the flanges.  From road bikes to trail bikes, the XMR is a solid choice for 6-bolt set ups.  Made in our shop from U.S. sourced 6061-T6 aluminum, they’re available in a range of drillings, colors, and axle configurations.

A question we always get about our disc hubs is, “CLD or XMR? Which is better?”.  Neither is “better” than the other. Both share the same internals and the differences really come down to the respective designs having to accommodate the two different rotor mounting interfaces.  Bottom line is you really can’t go wrong with either hub!
