Hyperglide (HG) series 10-speed compatible chain, recommended for Ultegra drivetrains
HG technology has chamfered inner plates to optimise shifting performance on HG sprockets
Durability is assured through a chromising treatment on link pins, and the heat treatment of rollers, pins, and plates
Mushrooming of the pins gives unsurpassed side-plate retention, enabling the chain to far exceed the BS/ISO standard for breaking force
5.88 mm chain width, optimised for 10-speedSuperNarrow HG drivetrains
Zinc-alloy silver finish on outer plates, and grey finish on inner plates increase corrosion resistance
