This Shimano Ultegra 6600 10 speed chain is a Hyperglide (HG) series model and is recommended for Ultegra drivetrains. 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.
- HyperGlide (HG) technology has chamfered inner plates to optimise shifting performance on HG sprockets.
- Durability enhanced by chromising treatment on link pins, and heat-treated rollers, pins and plates.
- Machine pressing of the pins gives unsurpassed side-plate retention, enabling the chain to far exceed the BS/ISO standard for breaking force.
- 5.88mm chain width, optimised for 10-speed SuperNarrow HG drivetrains.
- Zinc-alloy silver finish on outer plates and grey finish on inner plates increase corrosion resistance.
