Convert your Superboost Centerlock hubs to fit Shimano HG, Micro Spline or SRAM XD cassettes with our cutting-edge technology.

Gen 4 conversion kits include a pre-assembled axle, a freehub body and an adjustment collar for simple and quick installation. Installation requires a 2.5 mm Allen key and a T10 Torx key.

This new version of our hubs uses a 157 x 12 mm Gen 4 axle and a Gen 4 MTB freehub body.

Compatible with Superboost Centerlock hubs. Serial numbers begin with 871.

Compatible with ISO DH Gen 2 hubs when used with a "Micro Spline" adjustment collar (sold separately). Serial numbers begin with 291.

157 x 12 mm axle.

Available with stainless steel or ceramic bearings.

Available in silver or black.

If your hub is already fitted with a Gen 4 axle, changing the cassette interface is limited to replacing the freehub body.
