DT Swiss Cassette Ratchet Kit

This kit is designed for DT Swiss hubs utilizing the Star Ratchet system. You should verify your hub model and ensure it uses the standard Star Ratchet mechanism, as this kit is not compatible with DT Swiss Pawl-drive hubs or the newer Ratchet EXP system.

You must use the included DT Swiss specialized grease. Standard bike grease is too thick and will cause the ratchets to stick or engage poorly, which can lead to slipping under load.

For most riders, servicing the hub once a year is sufficient. If you frequently ride in wet, muddy, or dusty conditions, you should inspect and service the ratchet mechanism more often to prevent premature wear.

Generally, no. The DT Swiss Star Ratchet system is designed to be serviced without proprietary tools. You can typically disassemble the hub and replace the ratchets and springs by hand, though a clean workspace is essential to keep debris out of the hub internals.

Yes, if the slipping is caused by worn-out ratchet teeth or collapsed springs, this kit will resolve the issue. However, if the hub shell or axle is damaged, replacing the ratchets alone may not fix the problem.
