This freehub body is used to convert all DEG DT Swiss hubs to a Micro Spline driver. This does not include the ratchets or springs, and will just replace your current XD or HG freehub body. This freehub body will work with 12×142, 148, or 157 rear hubs. The different hub shell sizes make up the difference, and all sizes use the same included end cap. Bearings are pre-installed.Not compatible with previous generation ratchet or EXP DT Swiss hubs, only compatible with the newest DEG style DT Swiss 350 and 240 hubs.
