These are also required for conversion if not already present. The right-hand end stops for older systems, such as 3-pawl or Ratchet Star, are also compatible with the new freehub bodies.

Not compatible with road bike hubs and wheelsets.
Not suitable for converting hubs to a different installation dimension

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 tailored 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.

These Micro Spline MTB freehub bodies for mountain bike hubs are 1 mm narrower than the version for road bike hubs and therefore cannot be used on road bike hubs or road bike rear wheels.
