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.

After setting the benchmark in mountain bike components with SHIMANO XTR M9100 and the 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 the 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.
