Shimano Deore RD-M6100 SGS 1x12-speed MTB rear derailleur

The SHIMANO DEORE RD-M6100-SGS is a MTB rear derailleur designed for the 1x12-speed drivetrains in the Deore M6100 range. Directly inheriting the technologies developed for the SLX, XT and XTR groupsets, it offers fast, precise and silent gear changes, even on the most demanding terrain. Thanks to its modern design and excellent value for money, it's a must-have for Cross-Country, Trail, All-Mountain and Enduro riders.

The RD-M6100-SGS features SHIMANO SHADOW RD+ technology, equipped with a chain stabiliser that limits parasitic drivetrain movements. This system effectively reduces chain jumping and rattling noises and improves stability on technical sections and steep descents. Its low profile also helps protect the derailleur from shocks and stones.

Designed to work with Shimano 12-speed sprockets with up to 51 teeth, this model offers a wide development range, ideal for both steep climbs and fast sections. The 13-tooth sprockets optimise transmission fluidity, reduce friction and improve the bike's overall performance.

Its robust aluminium construction combined with high-quality internal components ensures excellent durability, even under intensive use. Compatible with Shimano HG 12-speed chains, the RD-M6100-SGS guarantees perfect synergy with HYPERGLIDE+ technologies for particularly smooth gear changes under load.
