The Shimano HG75 10 Speed HG-X Chain is a Hyperglide (HG-X) series 10-speed directional Dyna-Sys compatible chain for use with 10-speed MTB drivetrains. The HG-X Chain uses a directional design with specifically shaped inner & outer plates to optimise shifting over the chainset & cassette. Outer plate design has been developed to reduce the chance of chain suck while, The inner plate gives better contact with gears providing smoother shifting under high load, giving efficient pedalling, increased rigidity & near silent running. Durability is assured through a chromising treatment on link pins, & the heat treatment of rollers, pins, & plates with an open design of inner links increase mud shedding ability. The Sil-Tec surface treatment technology (PTFE plating) that is smooth running & increases durability.
