ZIPP SUPER9 B1/ZR1 SL Freehub Body SRAM XDR Type #11.2028.067.002

The ZIPP SUPER9 B1/ZR1 SL SRAM XDR Freehub Body fits Super9 B1 and ZR1 SL hubs with the SRAM XDR standard, used by 12-speed road cassettes (including AXS groups) with a smallest sprocket down to 10 teeth. This genuine ZIPP part allows you to replace a worn freehub body or convert the hub to this standard.

This freehub body is supplied with 61803 ceramic bearings, reducing internal friction compared with conventional steel bearings for optimised efficiency on high-end ZR1 SL hubs.

Compatible with ZIPP Super9 B1 (track/road) and ZR1 SL hubs, this kit is intended for riders using a SRAM AXS 12-speed drivetrain.
