Shimano XT RD-M8100 12S rear derailleur

The new, even more efficient Shimano M8100 rear derailleur. In the last few years the popularity of the bicycle has exceeded all expectations. Athletes and trail builders constantly push the limits of components and cycling equipment. And it's definitely not a problem for the beloved Japanese manufacturer. Furthermore it is the main engine of evolution and quality improvement for the Shimano team.

To meet the needs of cyclists at all levels, Shimano "smashes" the market with the new, unbeatable, in terms of quality / price ratio, 12-speed group Deore XT M8100. The components have undergone some fundamental changes. Thus, the RD-M8100 derailleur features a new 13-tooth pulley that manages chain tensioning in an optimal way, the rubber "bumper" on the bottom that protects the construction, offering silent functioning on rough terrain, and resumes the Shadow RD+ friction system for uninterrupted descents.
