Shimano XT RD-M8100 Long Cage 12V 2019

The new, even more efficient gearbox Shimano M8100.

In recent years the popularity of the bicycle has exceeded all expectations. Athletes and trail builders are constantly pushing the limits of components and equipment nowadays. Something that does not intimidate in any way the beloved Japanese house, on the contrary, it represents the main engine of evolution and quality improvement.

To meet the needs of cyclists at all levels, Shimano "breaks through" the doors of 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 gearbox features new 13-tooth pulleys that manage chain tensioning in an optimal way, the rubber "bumper" on the bottom that protects the construction, offering silent operation on rough terrain, and resumes the Shadow RD+ clutch for descents without unpleasant interruptions.
