240 - The winning choice: the 240 hub with Ratchet EXP and Ratchet DEG. The 240 hub is designed for the most ambitious riders. You can choose between two 240 hubs: one with a weight advantage thanks to the Ratchet EXP® system, or one with a reduced engagement angle thanks to the patent-pending Ratchet DEG® system. The EXP system has fewer parts and is available in 36 and 54 teeth. The Ratchet DEG has 90 teeth but also ensures high reliability thanks to its wider design.
