Upgrade your DT Swiss hub with Ratchet freewheel system with this kit. With extra teeth, providing more locking points than the originally installed toothed discs and thus offer a noticeably less free travel until the adhesion is achieved. Especially for hard starts or in technically difficult terrain, the more direct power transmission offers significant advantages. The DT Swiss Ratchet System enables tool-free disassembly of the freehub body. Thus, the toothed discs can be easily exchanged in a few minutes. NOTE: It is always necessary to change the toothed discs and springs at the same time! To grease the toothed discs, the use of DT Swiss special grease is recommended.
