Shimano CN-HG54 HG-X Directional Chain 

• Hyperglide (HG-X) series 10-speed directional Dyna-Sys compatible chain for use with 10-speed MTB drivetrains
• HG-X Chain uses a directional design with specifically shaped inner and outer plates to optimise 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 pedalling, increased rigidity and near silent running
• Durability is assured through a chromising treatment on link pins, and the heat treatment of rollers, pins, and plates
• Open design of inner links increase 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 optimised for Shimano 10-speed HG-X MTB drivetrains only
• Corrosion-resistant grey finish on inner and outer plates
• 116 links, 274 grams
