Shimano's Deore M6100 series is aptly designed for mountain bikers who aim to shred singletracks without a hitch. The Deore CN-M6100 Chain is no exception. This chain provides smooth shifting and enhanced chain retention. An extended portion of the inner plate makes this possible, and also shorter shifting time with less shock from pedaling. This proprietary design ensures smooth shifting and strength for riders while they barrel downhill. The Deore CN-M6100 Chain features quick-link assembly and is optimized for Hyperglide cassettes and dynamic chain engagement-plus chainrings.
