Cassette SHIMANO DEORE CS-M6100-12 - 10x51 12v - ICSM610012051

The SHIMANO DEORE CS-M6100-12 cassette is a must-have for Cross-Country, Trail, All-Mountain and Enduro mountain bikers looking for a high-performance, reliable and affordable drivetrain. Developed using technologies from the top-of-the-range Shimano groupsets, it offers an exceptional development range from 10 to 51 teeth, making it possible to tackle the most demanding climbs while maintaining excellent speed on rolling sections.

Compatible with Shimano 12-speed transmissions, this cassette features HYPERGLIDE+ technology, renowned for its ultra-smooth, fast gear changes, even under heavy loads. Unlike previous generations, it allows you to continue pedalling efficiently during gear changes, improving performance and control on technical terrain.

The aluminium BEAM SPIDER construction reduces the overall weight of the cassette while increasing its rigidity. This design optimises power transfer and improves the durability of the whole assembly, even when used intensively in the mountains or on challenging courses. The twelve steel sprockets guarantee excellent resistance to wear over the long term.

Designed to work exclusively with a MICRO SPLINE freewheel body, the CS-M6100-12 allows the use of a small 10-tooth sprocket, offering a particularly wide development range. This technology helps improve pedalling efficiency while maintaining optimised tooth spacing between gears.

Thanks to its excellent value for money, this cassette is an ideal solution for replacing a worn drivetrain or equipping a 12-speed bike with a reliable, high-performance and durable component based on Shimano know-how.
