Top-of-the-line rear derailleur RD - M786 from the XT group, with Top Normal system for fast and precise shifting, and Shadow Plus. Combined with Rapid Fire levers, it allows even intuitive gear control in extremely difficult conditions. Shadow technology means that the derailleur has a very flattened profile, which minimizes the likelihood of hitting any obstacle on the trail. In addition, the new derailleur has a vertically stiffened design, so instances of hitting the frame while riding in really bumpy terrain are expected to be a thing of the past. The treatment should positively affect the derailleur's behavior at high speeds.
