Ultegra/Deore XT CN-M8100 138 Link 12sp Chain
$71.99
The Shimano CN-M8100 is a 12-speed chain built for Ultegra and Deore XT drivetrains across road and off-road use. Its extended inner plate improves chain engagement, part of Shimano's Dynamic Chain Engagement+ design that supports smooth shifting and consistent retention under load.
A SIL-TEC surface treatment adds extended durability for off-road riding conditions, and the chain connects using a quick-link that is not reusable once removed. A dedicated pliers tool makes installing or removing the quick-link straightforward, keeping chain replacement quick during routine maintenance.
