DT Swiss Ratchet Freehub Body - Shimano Micro Spline Road, Light, Aluminum, Ball Bearing, w/ End Cap, 12 x 142 mm FW0199

Ratchet freehub bodies have a gloss finish and don't have a seal, as this is fixed on the hub shell. The Ratchet System was the first of this type for DT Swiss; used in the mid-range products like the 350 hubs.
