Shimano Deore XT / Ultegra CN-M8100 Chain — 12-Speed, 126 Links, HYPERGLIDE+, Quick-Link, MTB/Road

The Shimano CN-M8100 is the 12-speed HYPERGLIDE+ chain shared across Deore XT and Ultegra, with SIL-TEC surface treatment for quiet, durable, smooth shifting.

Genuine Shimano, brand new in retail packaging.

Will it fit? For Shimano 12-speed HYPERGLIDE+ drivetrains (XT, SLX, Deore M-series and Ultegra 12-speed road). This is the 126 link length, the one to choose for a wide-range cassette, a large chainring or a long chainstay. E-bike approved, with the SM-CN910-12 Quick-Link included. Not for 11-speed.
