When it comes down to performance and durability the new Rival 22 rear derailleur matches the top end Force and Red derailleurs with the only difference being a slight weight difference. The derailleur is constructed from an aluminium inner and outer cage as well as an aluminium b-knuckle. Using Exact Actuation, each gear shift is fast and accurate, with the redesigned AeroGlide jockey wheels keeping things quiet and smooth.
