The FSA/Vision Metron PRS SRAM XDR freehub body brings SRAM's 12-speed XDR cassette standard to compatible Metron PRS disc brake wheelsets. Built from alloy, this freehub body replaces a worn or incompatible unit, letting riders switch between drivetrain standards without purchasing an entirely new hub. It arrives with its bearing pre-installed, simplifying the swap and reducing extra parts to source separately.
This freehub body fits Metron 45, 60, and 81 SL Disc Brake wheels equipped with PRS hubs from model year 2022 onward. Riders running SRAM XDR-compatible cassettes on these wheelsets can install this part directly, maintaining proper spline engagement and bearing support. It suits home mechanics and shops servicing FSA and Vision wheelsets needing an XDR-specific freehub upgrade or replacement.
