DT Swiss freehub using the 3 pawl mechanism found on DT Swiss wheelset. This will not work on any hub like the 240 and 350 hubs with the twin ratchet ring mechanism.
Any DT Swiss branded hub (some syncros wheels use these freehubs) that uses the 3 pawl mechanism should use this freehub.
This is for 8/9/10/11 speed MTB cassettes or 8/9/10 speed road cassettes only.
Three versions. 1) Freehub only, 2) freehub and DS end cap for Q/R, 3) Freehub and DS end cap for 142x12mm.
