What Makes the DT Swiss Ratchet Freehub Body the Right Choice?

The DT Swiss Ratchet Freehub Body is the original service and upgrade driver for the 350-series hub lineup, giving you a correct replacement without having to step up to a higher-tier hub system. The Ratchet System was DT Swiss's first iteration of their now-legendary star ratchet engagement architecture, and it remains the accurate spec for mid-range wheels built around the 350 platform. The gloss finish is intentional: there is no external seal on this body because sealing is handled at the hub shell itself, a deliberate design choice that keeps the interface clean and service straightforward.

This body is spec'd for the SRAM XDR driver standard, supporting 12-speed road and gravel cassettes across the AXS ecosystem. Installation is a direct drop-in on any DT Swiss hub using the Ratchet System freehub interface. Whether you are converting a wheel from Shimano HG to XDR or simply replacing a worn driver on a 350 hub, this is the correct part and it installs cleanly without modification.

FAQ

What is the difference between the Ratchet System and Ratchet EXP?

The Ratchet System is the original mid-range engagement design used in the 350-series hubs. Ratchet EXP is the updated high-engagement version found in the 180 and 240 series. The two systems use different freehub bodies and are not interchangeable.

Can I use this body to switch my 350 hub from Shimano to SRAM AXS?

Yes. If your DT Swiss hub currently uses a Shimano HG freehub body, swapping to this XDR body lets you run any SRAM 12-speed road or gravel cassette.

Why does this freehub body have no external seal?

DT Swiss designed the 350 hub so that the seal lives on the hub shell, not on the freehub body. This keeps the contact interface clean and simplifies driver swaps without compromising weather protection.

Best For

Road and gravel riders on DT Swiss 350 hubs who are transitioning to SRAM AXS and need the correct OEM Ratchet System body to run 12-speed XDR cassettes.
