Sram Xd/Xdr Freehub
🚚 Delivery Estimated between 10 December and 15 December.
XD and XDR rear hub driver bodies establish universal mounting systems for cassettes that incorporate cogs with fewer than 11 teeth for more versatile drivetrains. The interfaces make light weight wide-range cassettes possible without requiring new rear axle standards, hub redesigns, or even new cassette tools.
The XD interface is designed for mountain bike applications and maintains the same hub spacing and flange locations used for 8, 9, and 10-speed compatible HyperGlide freehub bodies.
The XDR interface is 1.85mm longer than XD and is designed for road hub applications. XDR maintains the same hub spacing and flange locations used for 11-speed road compatible HyperGlide freehub bodies. XDR driver bodies are compatible with all XD cassettes when the cassette is installed with a 1.85mm spacer behind it.
SRAM offers the use of XD and XDR interfaces and trademarks to companies that conform to the technical specifications of the designs and agree to abide by the terms of our license agreement. Currently, 170+ companies have been granted licenses to make hubs and wheelsets that incorporate either XD or XDR drivers, making them the most widely adopted 10-tooth start freehub body designs in the cycling world.
