The DT Swiss Ratchet Freehub Body is a lightweight aluminum component that fits Shimano 12-speed Micro Spline cassettes. It has a gloss finish and no seal, as this is fixed on the hub shell. This Ratchet System was the first of its type for DT Swiss, used in mid-range products like the 350 hubs.
The Ratchet Freehub Body comes with an end cap for 12 x 142 and 12 x 148mm hubs, and is compatible with 12mm thru-axles. It's a great choice for those looking for a reliable and lightweight freehub body.
