DT Swiss Star Ratchet Kit

The 54t Star Ratchet Kit is compatible with all current DT Swiss star ratchet hubs, including the 180, 240S, 350, 370 LN, and 540 models.

Upgrading to 54 teeth reduces the engagement angle to 6.66 degrees, compared to the 20 degrees of the standard 18-tooth system. This results in near-instantaneous power transfer and significantly less pedal slop when you start pedaling.

Yes, this is a direct replacement kit that does not require specialized tools for most DT Swiss star ratchet hubs. You can typically remove the end caps and freehub body by hand to swap the ratchets and springs.

Yes, the 54t system produces a faster, higher-pitched, and more pronounced engagement sound compared to the standard 18t ratchets. Many riders find this audible feedback satisfying, though it is noticeably louder.

Yes, it is essential to use the provided Molykote grease during installation. DT Swiss star ratchets require a specific thin layer of this grease to function correctly and prevent premature wear.
