240 - The number you can rely on. The 240 has been designed for drivers with the highest demands. Whether you want to take advantage of the weight benefit of the DT Swiss Ratchet?EXP systems, the small engagement angle of the Ratchet?DEG, the reduced pedal kickback with Ratchet?DEG?DF, or the proven durability of the Ratchet?System?18 for single-speed use – there is the right system for you. The EXP system offers fewer individual parts, while Ratchet?DEG features a 90-tooth engagement system with the well-known reliability thanks to its larger design.
Ratchet?DEG?DF allows for 0°, 10°, or 20° freewheel rotation before engagement, thereby minimizing pedal kickback.
