DT Swiss 370/Onyx Service Kit

This kit contains the essential components to refresh your hub's engagement mechanism, specifically including two pawls, the necessary spring, and a packet of specialized grease.

This kit is designed specifically for DT Swiss 370 and Onyx hubs. Before purchasing, verify that your hub model matches these specifications, as internal engagement systems vary significantly between different hub series.

Servicing a hub pawl system is a moderate task that requires basic mechanical aptitude and a few standard tools. If you are comfortable removing the freehub body and cleaning internal components, you should find this straightforward, though you should consult the DT Swiss technical manual for your specific hub model.

The frequency of service depends on your riding conditions and mileage. As a general rule, if you notice the engagement feeling sluggish, hear unusual noises, or have ridden extensively in wet or dusty conditions, it is time to clean the internals and install these fresh components.

It is highly recommended to use the specific grease included in the kit or a manufacturer-approved equivalent. Using the wrong consistency of grease can cause the pawls to stick or fail to engage properly, which can lead to slipping under load.
