DT Swiss Aluminium Rotor Hubs, Ratchet EXP Sprocket System – Road Bike Hubs, Superlight Ceramic Bearings, for Shimano 12-speed Micro Spline cassettes plus right-hand end stop for 12x142/148/157mm thru-axle assembly
EXP Freehub Body DT Swiss Micro Spline
The high-end freehub body from the EXP series with Sinc Ceramic bearings
For converting DT Swiss 240 EXP road bike hubs, road bike and gravel rear wheels with the Ratchet EXP system, to the Shimano Micro Spline system for 12-speed Micro Spline cassettes.
These Micro Spline freehub bodies for road bike hubs are 1 mm wider than the version for MTB hubs, thus enabling the use of MTB Micro Spline cassettes on road bikes and gravel bikes.
- The kit includes the freehub body and the right-hand frame end cap for 12x142mm, 12x148mm or 12x157mm thru-axle mounting. The right-hand end caps for the mounting dimensions are the same; the hub widths differ.
- The Ratchet EXP freehub bodies are only compatible with DT Swiss 240 EXP and 180 EXP road bike hubs and rear wheels fitted with these hubs. A separate version is available for DT Swiss MTB hubs.
- DT Swiss manufactures specific right-hand end stops for each cassette system, such as Shimano HG10, Shimano HG11, Shimano Micro Spline, Sram XD, Sram XDR, Campa ED and Campa N3W. 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 Pawl / 3-pawl, Ratchet LN, Ratchet Star, Ratchet DEG hubs.
Not compatible with MTB hubs and wheelsets.
Not suitable for converting hubs to a different installation size
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.
