The Shimano SLX RD-M7100 1x12-speed rear derailleur for 10-51 cassette features an elegant yet aggressive angled design and an attractive anodised aluminium surface. The derailleurs feature bigger 13-tooth pulleys and include Shimano’s proven Shadow RD+ low profile technology.

The use of a single or a double system requires the installation of the specific single or double rear derailleur. The new construction of the low-profile RD-M7100 SHADOW RD+ rear derailleur improves shift quality, range of adjustment and chain retention while allowing for a wide range of gearing options. 
After setting the benchmark in mountain bike components with SHIMANO XTR M9100 and new DEORE XT M8100, Shimano rounds out its now entirely 12-speed performance mountain bike component lines with new SLX M7100. SLX M7100 cascades technology from new XTR M9100 and DEORE XT M8100 - namely Shimano’s signature premium shifting and braking performance - while maintaining the SLX hallmark of value and durability.
