A new XTR group also means a new chain. The M981 is a directional 10-speed design; it features hollow pins and debuts a special coating Shimano refer to as Sil-tec – in theory that should mean a part that runs smoother and lasts longer.
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
Hollow link pins offer great weight savings
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
Chain is optimised for Shimano 10-speed HG-X MTB drivetrains only
Sil-Tec surface treatment technology (PTFE plating) that is smooth running and increases durability
