- The Shimano Alivio rear derailleur with Shadow RD technology is even better than its predecessor for trail and trekking use
- Thanks to the very flat design and the optimised spring tension, a stop on the chain stay is prevented and even trail obstacles have hardly a chance to damage the rear derailleur.
- The rear derailleur supports nine gear levels and the HyperGlide system which protects the drive components from premature wear.
