recommended for Altus and older Alivio / STX drivetrains.

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.

drivetrains.
