240 – The winning number. The 240 is designed for riders with the most extreme ambitions. Whether you want to rely on the 240 with the weight advantage of the DT Swiss Ratchet EXP system, the low engagement angle of the Ratchet DEG, the reduction in pedal kickback provided by the Ratchet DEG DF, or the proven durability of the Ratchet System 18 for single-speed applications, there’s a system to suit you. The EXP system features fewer components, whilst the Ratchet DEG boasts a 90-tooth system ensuring very rapid engagement and proven reliability thanks to its larger design.
The Ratchet DEG DF allows the freewheel body to rotate by 0°, 10° or 20° before engagement, thereby minimising pedal kickback as much as possible.
