The new, even more efficient shimano m8100 gearbox
In recent years, the popularity of the bicycle has exceeded all expectations. The athletes and trail builders constantly push the limits of components and equipment today. Which does not intimidate in any way L'beloved Japanese house, indeed, represents the main engine of evolution and quality improvement.

Thus, the RD-M8100 gearbox has new 13-teeth pulleys that manage the tensioning of the chain in an optimal way, the rubber "bumper" on the lower part that protects the construction, offering silent operation on the rough terrain, and resumes the Shadow RD+ clutch for the descents without unpleasant interruptions.
