XD: More Power to the Pedal

SRAM XD is a new cassette driver body design that lets riders tap the power and range of the SRAM XX 10-42 11-speed cassette and a 10-tooth small cog.

The XD design provides an improved interface with the cassette without impacting the bearing location, ratchet mechanism, or axle of the hub. No frame modifications are necessary to accept an XD-equipped wheel and cassette.

A New Standard

SRAM’s new XD driver body establishes one universal mounting system for cassettes with cogs of less than 11 teeth. This new standard makes wide-range cassettes more readily available and beneficial to manufacturers and riders by greatly simplifying installation.
