Description

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 optimize shifting performance on HG sprockets & comes with a 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.
