Shimano CN-M8100 XT/Ultegra Chain 12 Speed Chain

Shimano CN-M8100 XT / Ultegra 12-Speed Chain – 116 Links (ICNM8100116Q | UPC: 192790443898)

The premium 12-speed chain at the heart of Shimano's Ultegra R8100, XT M8100, and GRX 800 series groupsets. Includes the reusable Quick-Link (SM-CN910-12) for effortless, tool-free installation and servicing.

Chrome-treated inner plates combined with SIL-TEC outer plates slash friction, minimize noise, and boost longevity – even through grimy MTB trails or rainy road miles. Hollow chromized pins and asymmetric perforated design trim weight while ramping up rigidity for flawless Hyperglide+ shifts under torque.
