Shimano Acera RD-M3020 8-speed Rear Derailleur

Shimano Acera Rear Derailleur RD-M3020 - Wide compatibility for 8-speed derailleurs

The RD-M3020 rear derailleur from Shimano's Acera series is used on mountain and urban bikes with 8-speed or certain 7-speed gears. Compared to the RD-M360 model, the wide compatibility is worth highlighting: The total capacity is 45 teeth, whereby the largest sprocket of the cassette can have a maximum of 40 teeth. A maximum of 12 teeth is possible on the smallest sprocket. The rear derailleur impresses with precise, fluid gear changes that are reliable even in rough terrain. It is mainly made of steel and has a cable adjuster. The derailleur pulleys have 11 teeth.
