Shimano Ultegra CN-M8100 12v road bike chain 114 maillons Quicklink

The Shimano CN-M8100 12-speed chain 114 maillons with Quick-Link is a high-performance solution for road cyclists seeking a smooth, precise and durable drivetrain. Originally developed as part of the Deore XT range Shimano, this chain features Hyperglide+ technology and offers excellent performance, making it ideal for compatible 12-speed drivetrains used on the road.

Thanks to its specific design, it guarantees fast and smooth gear changes, whilst ensuring excellent power transfer between the crankset and the rear wheel. It therefore meets the expectations of competitive cyclists, racers and regular riders who wish to maintain an efficient drivetrain.

Smooth and precise gear changes on the road

Shimano ’s Hyperglide+ technology optimises the chain’s engagement with the teeth on the cassette and chainrings. Gear changes become smoother and more precise, allowing you to maintain a steady cadence during accelerations, sprints and changes of pace.

This design is particularly beneficial on the road, where a consistent pedalling rhythm and precise drivetrain performance directly contribute to riding comfort.

A design focused on performance and durability

The CN-M8100 Shimano features extended inner plates that improve contact with the teeth and ensure excellent chain retention.

Its inner plates feature Shimano ’s SIL-TEC surface treatment, which reduces friction and improves wear resistance. This technology also helps to minimise drivetrain noise and maintain smooth operation over long distances.

Whether for training rides, long distances or hilly routes, this chain offers reliable and smooth performance.

Easy fitting with the Quick-Link

Supplied with a Shimano Quick-Link SM-CN910-12, the CN-M8100 chain makes it easy to fit and close the drivetrain.

Its length 114 maillons is well suited to many 12-speed road bike set-ups. It can be adapted to different drivetrain configurations, provided you check the required length based on the crankset, cassette and frame geometry.

The Quick-Link allows for a simple and secure connection, without the need for traditional riveting. It is, however, designed for single-use only.
