Refresh your bearings and update your Chris King R45 or Classic hub to 11 speed in one fell swoop by replacing your existing driveshell. This current driveshell is slightly longer than the original which allows for 11 speed cassettes.
The body is perfectly machined from aluminum billet. Inside of the drive shell are pre-installed Chris King bearings, which makes installation a breeze. If you look closely at the splines, you will notice two machined stripes that run perpendicular in the center of the freehub body. This is the indicator that the driveshell is 11 speed compatible. Compatible with R45 hub.
This driveshell will upgrade existing Chris King hubs to work with 11 speed drivetrains, but will still have compatibility with 8, 9 or 10 speed systems.
