This narrow-wide 1x12 ring is built for Shimano direct-mount cranks and tuned for an ideal chainline, giving you smooth, reliable shifting across the full cassette. It installs as a direct replacement for SM-CRM75, SM-CRM85 and SM-CRM95 rings, and its one-piece 7075 T6 aluminum construction keeps weight low while delivering excellent strength for long-lasting performance.
