SINC ceramic ball bearings have been developed by DT Swiss as a system. They are based on balls made from the ceramic material silicon nitride, Si3N4, which is extremely durable and resistant to wear and corrosion. The bearing rings are made from a specially developed steel alloy adapted to the properties of the ceramic material and are precision-ground. This combination reduces rolling resistance to an absolute minimum and ensures a longer service life compared to conventional ball bearings.

The SRAM XDR freehub body system allows the installation of SRAM 12-speed road bike cassettes on DT Swiss wheels. The DT Swiss XDR freehub body offers the option to convert your rear wheel to this system. These freehub bodies differ from the MTB XDR freehub bodies in that they are 1.8 mm wider. Total width 35.9 mm, cassette mounting depth 30.3 mm. These freehub bodies can also be used with SRAM MTB XG cassettes. In this case, the cassette sits 1.8 mm further out.
