What Makes the Black Inc X Freehub Body Built for SRAM XDR?

The Black Inc X Freehub Body for SRAM XDR is built around a 30-tooth engagement mechanism that delivers near-instant power transfer the moment you push on the pedals. It is available in two bearing options: standard stainless steel or an upgrade to CeramicSpeed ceramic bearings, the same spec Black Inc uses across all their complete hub builds. Low friction is the core engineering goal here, so your drivetrain efficiency is not capped by a component most riders never think twice about. If you are running Black Inc wheels or any hub that accepts the XDR standard, this freehub body holds that same performance bar.

Compatible with SRAM 12-speed road and gravel drivetrains, the SRAM XDR interface fits RED, Force, and Rival AXS cassettes right out of the box. The CeramicSpeed bearing upgrade is sourced directly through Black Inc's partnership with CeramicSpeed, so you are getting the exact spec used in their full wheel builds rather than an aftermarket alternative. Stainless steel bearings are the right call for riders who want reliable performance at a lower price point without sacrificing durability. Either way, this freehub body matches the quality standard of the wheelset it goes into.
