Shimano's CN-HG601-11 chain boasts an ultra-low friction surface treatment, known as SIL-TEC, which enhances performance and durability in all conditions. In addition to their already impressive 11-speed products, Shimano has expanded its range with the new CN900 11-speed quick link, which offers greater versatility. This quick link enables tool-free removal and installation of your Shimano 11-speed chain, making trail-side repairs a breeze. This 126-link chain is compatible with Road/Mountain/E-Bike 11-speed, and features a solid pin design, SIL-TEC surface treatment with PTFE coating on inner and outer links and rollers, and a HG-X11 special asymmetric plate design for 11-speed. The Shimano Quick Link (SM-CN900-11) is included for easy installation and removal.
