After the flagship XTR mountain bike has already set standards and the Deore XT and SLX have followed suit, the Deore M6100 now rounds out Shimano's 12-speed lineup. It is complemented by components from the M5100 and M4100 series, which will equip the 11 and 10 speed motors to the same level.

Shimano Deore's current groupsets are in the entry price range and are not prepared to compromise on performance, quality and reliability. Almost everything that distinguishes the big brothers in terms of technology, innovation, performance and functionality can also be found in Deore components.

The Shimano Deore RD-M6100-SGS rear derailleur guarantees quick and precise gear changes over a huge range of ratios. The Top Normal rear derailleur for the Deore 1x12-speed drivetrain is perfectly matched to the large 10-51 Shimano CS-M6100 cassette and incorporates Shadow RD+ technology, already known from the Deore XT and SLX models, for a quiet ride and safe stay of the chain.
Shadow DR+

Quiet drive, less distraction. The Shadow RD+ system is lighter and more efficient than roller chain devices. A rear derailleur stabilizer not only reduces chain slack, but also offers a simple solution to prevent chain jump.
