DT Swiss Star Ratchet Upgrade Install
We recommend DT Swiss hubs because they’re a proven hub with great performance aspects. Oftentimes what really pushes us for a DT Swiss hub over similarly priced and performing competitors though is its easy serviceability and availability of parts. Today, I’m here to show you how to install new ratchets in the rear hub. This could be maintenance or an upgrade to the faster engaging 54 tooth ratchet system.
Once you’ve purchased your 54T upgrade or replacement for a 36T or 18T system you’ll get the above components. Two drive rings, two conical springs and a small tub of DT Swiss star ratchet grease. The next steps will be to grab your hub and dismantle the freehub body assembly to access the ratchet system.
Remove the Freehub Body
There’s other ways to pull the end cap off and you can use your imagination but the proper way to do so is to place the drive side end cap in an axle vice. We happen to use the Park Tools axle vice (AV-5 or AV-1 models will work) adapter. Once secure you can simply pull on the hub body and with a bit of work the end cap will simply slide off the axle and you can slide the freehub body off to access the ratchet system.
Once you have the old ratchets out clean the entire hub internals. Make sure to keep any solvent or degreaser away from the seals on your bearings. Next lube up the new ratchets and the internals of the hub with the DT Swiss ratchet grease. Once cleaned and prepped assembling the hub is simple and involves sliding the six individual components into place. The order goes conical spring => ratchet drive ring => ratchet drive ring =>conical spring => freehub body => end cap. Take a look at the pictures for a more detailed step by step process.

Nothing really to say to sum this up. At this point you can get back out and ride your hub. Like I said the DT Swiss hubs are easy to maintain, making them an easy choice for your next wheel set.
