DT Swiss Upgrade Kit for Ratchet EXP Hubs

A 54-tooth service kit for compatible DT Swiss Ratchet EXP hubs. Supplied with both ratchets, the spring and DT Swiss ratchet grease, it keeps the matching engagement parts together for the rebuild.

Use only with the Ratchet EXP mechanism. It does not fit Ratchet EXP Oversized or the original twin-sprung Ratchet system.

Installation requires the matching ring-nut tool (HBDT8387S) and Ratchet EXP driveside bearing tool (HBDT6106S), supplied separately. Confirm the hub and procedure in DT Swiss Product Support.
