DT Swiss Ratchet and Pawl Freehub Service Kit

The tooth count determines your engagement speed; higher counts like 54t offer faster, more immediate engagement, while lower counts like 18t are generally more durable and require less maintenance. You can choose based on your preference for snappy power transfer versus long-term reliability, provided the count is compatible with your specific hub model.

No, these systems are mechanically distinct. You must select the specific kit that matches your current hub's engagement mechanism, as parts for a Ratchet system are not interchangeable with a 3-Pawl system.

The EXP system is a newer design that simplifies the hub internals by using a single spring and a threaded ratchet ring, whereas the standard system uses two springs and two floating ratchets. Because of these structural differences, you must purchase the kit specifically designed for your hub's engagement architecture.

Yes, servicing DT Swiss hubs typically requires a specific ring nut tool to remove the threaded ratchet ring from the hub shell. Without the correct tool, you risk damaging the hub internals during installation.

We recommend servicing your hub every 6 to 12 months, depending on your riding conditions. If you frequently ride in wet, muddy, or dusty environments, you should perform maintenance more often to prevent premature wear on the ratchet teeth.

Most service kits include a small amount of DT Swiss special grease, but it is always worth checking the specific product listing to confirm. Using the correct proprietary grease is critical, as standard bike grease can be too thick and cause the ratchets to slip.
