Chain Shimano DEORE CN-HG54 10-speed OEM

HG-X Chain uses a directional design with specifically shaped inner and outer plates to optimize shifting over the chainset and cassette. Outer plate design has been developed to reduce the chance of chain suck. The inner plate has been developed for better contact with gears providing smoother shifting under high load, giving efficient pedaling, increased rigidity, and near-silent running. Durability is assured through a chromizing treatment on link pins, and the heat treatment of rollers, pins, and plates. Open design of inner links increases mud shedding ability. Mushrooming of the pins gives unsurpassed side-plate retention, enabling the chain to far exceed the BS/ISO standard for breaking force. Chain is optimized for Shimano 10-speed HG-X MTB drivetrains only. Corrosion-resistant grey finish on inner and outer plates.
