Been wanting to give your gravel bike a mullet drivetrain with Shimano components? Now you can add Chris King’s R45D hubs into that mix, too.
Chris King’s R45D road hubs now have a Micro Spline freehub body option, available on standalone hubs and complete wheels.
Available in Black or Silver, they’re compatible with all Center Lock R45D versions. They’ll also fit 2nd generation 6-bolt hubs with serial numbers starting with 6910. They fit Shimano’s mountain bike cassettes, which can be mixed with the new 12-speed GRX gravel components to create a wider-range 1x drivetrain on gravel bikes.
Existing Chris King hub owners can retrofit with the complete axle-and-freehub body combo for $250 with stainless steel bearings or $310 with ceramic bearings. 12×142 thru axles only.
