Description
Replacement freehub driver body for Onyx Racing Product hubs employing the MFU structure (modular freehub units).
- Compatible with all Vesper hubs, and newer Classic hubs.
- 6 models: Shimano HG, Shimano HG (chromoly), Shimano Micro Spline, Shimano Micro Spline (chromoly) Sram XDR, Sram XDR (chromoly).
- Note! Shimano Micro Spline and Campagnolo Campy driver bodies use different widget/endcap compared to the rest of the drivers! If one is moving over from one driver standard to the other (e.g. from XDR to MS or vice-versa), the widget/end cap needs to be replaced as well. All widget/end caps are compatible with the following hub spacing standards:
- MTB – 142x12mm.
- Boost – 148x12mm.
- Super Boost – 157x12mm
- FAT – 177x12mm
- FAT 197x12mm
- Ask for availability by email for endcaps compatible with other hub spacing options: info(at)onyxhubseurope.com
- Sram XD drivers are not included in the Onyx RP lineup. XD cassettes can be run with an XDR driver by installing a 1.85mm spacer under the cassette. The spacer is included in the delivery with all XDR drivers.
- Stainless steel versions are more durable and recommended for especially heavy applications such as e-bike or single-speed use. Vesper hubs use aluminium drivers in all applications.
- Ensure compatibility by email, if needed.
