DT Swiss Star Ratchet Kit

This kit is compatible with all DT Swiss hubs that utilize the Star Ratchet system. If your hub currently uses a Star Ratchet mechanism, these parts will fit, regardless of whether you are currently running 18t, 36t, or 54t ratchets.

The 18t ratchet is the standard configuration for DT Swiss hubs because it offers the highest durability and the most robust engagement surface area. It is the ideal choice if you prioritize long-term reliability and lower maintenance intervals over the faster engagement speed of 36t or 54t ratchets.

For most riders, a full service—cleaning the old grease and applying a fresh, thin layer of the included DT Swiss special grease—is recommended every 3,000 to 5,000 kilometers. If you frequently ride in wet, muddy, or dusty conditions, you should inspect and service the hub more often to prevent premature wear.

No special tools are required for a standard service or to replace the springs and ratchets. The Star Ratchet system is designed to be tool-free, allowing you to pull the freehub body off by hand to access the ratchets and springs for cleaning and maintenance.

It is best practice to always use the new springs included in this kit when replacing your ratchets. Springs can lose tension over time, and using the fresh springs ensures consistent pressure and reliable engagement.
