The Shimano XTR RD-M9100 11/12-speed rear derailleur 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.

High-quality 11/12-speed rear derailleur for precise and fast gear changes: XTR RD-M9100 from Shimano
