The Shimano Acera RD-M360 rear derailleur is suitable for 7 and 8-speed drivetrains. It has been designed according to the Wide-Link concept with further apart bearings, which increases rigidity and counteracts torsion under load. As a top-normal rear derailleur, the RD-M360 supports fast down shifting of multiple gears in the Shimano SIS indexing system.
