DT Swiss Ratchet EXP Freehub Body
DT Swiss Ratchet EXP Freehub Body Item # 1989682
Description
Replacement Freehub body for DT Swiss Ratchet EXP hubs.
Ratchet EXP is the lightest freehub system from DT Swiss and is therefore found in the highest specification versions of DT Swiss products like the 180 and 240 hubs.
The Ratchet EXP requires fewer single parts because of the integration of the ratchet and the threaded ring, which reduces the weight of the system. Only one guided spring is used, which ensures precise engagement.
Ratchet EXP freehub bodies have a matte finish. Ratchet EXP freehub bodies have no seal themselves, as this sits on the hub shell.
The ratchets for the Ratchet EXP System have 36 or 54 teeth. They differ from the classic Ratchet System in that the loose ratchet has a seat for the straight spring. The integration of the ratchet and the threaded ring in the Ratchet EXP also allows for a smaller number of parts due to the use of a single spring. This also reduces the weight of the freehub system.
