Hyperglide (HG) series 6, 7, or 8-speed compatible chain, recommended for Altus / Tourney and older Alivio / STX drivetrains. HG technology has chamfered inner plates to optimise shifting performance on HG sprockets & comes with quick and easy to use connecting link.
Durability is assured through the heat treatment of rollers, pins, and plates and mushrooming of the pins gives unsurpassed side-plate retention, enabling the chain to far exceed the BS/ISO standard for breaking force. The HG-40 chain is designed for precise index shifting on 6, 7, and 8-speed HYPERDRIVE SIS and DUAL SIS drivetrains.
