Tektro 9-speed shifting system for e-bikes

Centre motors tug at the chain, sprockets and rear derailleur with high torque. The wear on these parts is correspondingly high. With the E-Drive 9, Tektro presents a 9-speed derailleur system specially designed for the high forces of pedelec drives. It was developed in co-operation and coordination with Conway. The system consists of a sprocket set with a gradation of 11-13-16-20-24-28-34-40-46 teeth. Practical: The three smallest sprockets, which are subject to particularly high loads, are interchangeable. The rear derailleur has a clutch for increased chain tension.
