Affinity Comp 12-Speed XDR Driver Body
The Bontrager Affinity Comp 12-Speed XDR Driver Body replaces the freehub body on compatible Bontrager hubs, allowing riders to run SRAM XDR cassettes with 11 or 12-speed gearing. Swapping to this driver body opens the door to wider-range cassette options without changing the hub shell or wheel, keeping a current wheelset compatible with newer drivetrain standards.
This driver body fits Bontrager Race, Affinity Comp, and Rhythm Comp hubs, giving home mechanics and shops a straightforward way to update an existing wheel for SRAM-specific cassette bodies. Installation follows standard freehub service procedures, and the splined interface accepts XDR cassettes directly once the old driver body is removed.
