The Shimano CN-HG54 10-Speed HG-X Chain uses a directional design with specifically shaped inner and outer plates to optimise shifting over the chainset and cassette. Its outer plate design has been developed to reduce the chance of chain suck and the inner plate has been developed for better contact with gears providing smoother shifting under high load, giving efficient pedalling, increased rigidity and near-silent running.

• Chain is optimised for Shimano 10-speed HG-X MTB drivetrains  
• Mushrooming of the pins gives unsurpassed side-plate retention, enabling the chain to far exceed the BS/ISO standard for breaking force
• Corrosion-resistant grey finish on inner and outer plates
