DT SWISS Service Kit Ratchet Version with 54 Teeth for Ratchet EXP System

Faster Engagement. Precision Engineering. Reliable Performance.

Upgrade your rear hub's responsiveness with the DT Swiss Ratchet EXP 54T Service Kit, an original DT Swiss service and upgrade solution designed specifically for rear hubs equipped with the Ratchet EXP freehub system.

Featuring 54 precision-machined engagement teeth, this kit delivers a quick 6.67° engagement angle, reducing the rotational movement required before the freehub engages.

Whether replacing worn components or upgrading from a 36-tooth Ratchet EXP configuration, the 54T system provides a more immediate connection between pedalling input and rear-wheel engagement.

54 Teeth. Faster Engagement.

The DT Swiss Ratchet EXP 54T system offers 54 engagement positions per revolution, providing a noticeably more responsive drivetrain feel.

Compared with the 36T configuration, which features a 10° engagement angle, the 54T upgrade reduces the angle to approximately 6.67°.

This shorter engagement interval is particularly beneficial during rapid accelerations, technical climbs and situations requiring frequent adjustments to pedalling input.

The result is a direct, responsive riding experience with reduced freehub engagement delay.

Ratchet EXP Technology. Engineered for Reliability.

DT Swiss Ratchet EXP technology uses two interlocking toothed ratchet components to transfer pedalling torque through the rear hub.

Unlike conventional pawl-based freehub mechanisms, the ratchet design provides simultaneous engagement across its mating teeth.

The EXP system integrates one threaded ratchet into the hub, simplifying the freehub mechanism while maintaining reliable torque transmission.

The 54T service kit preserves the original Ratchet EXP architecture while providing finer engagement.

Precision Components. Dependable Performance.

Manufactured from durable steel, the ratchet components are engineered to withstand repeated engagement under demanding cycling conditions.

The kit includes the necessary ratchet components, spring, washer and DT Swiss special grease for servicing the compatible freehub mechanism.

Regular maintenance and correct lubrication help preserve smooth operation, consistent engagement and the long-term reliability of the system.

The DT Swiss Ratchet EXP 54T Service Kit is suitable for cyclists looking to restore worn engagement components or upgrade the responsiveness of an existing Ratchet EXP rear hub.
