Description

These MCS chain tensioners are CNC machined from 6061-T6 aluminium and suit 3/8 inch and 10mm axles. Tensioning is a single bolt job, so setting your chain is a quick task rather than a fight with the wheel.

Two axle positioning options let you use the full range of the dropout. They carry a laser etched MCS Bicycles logo and come anodised in black, blue, gold or red.

Features

Single bolt tensioning. One bolt does the tensioning, so setting your chain is quick and there is less to work loose.
CNC machined 6061-T6 aluminium. Machined from 6061-T6 aluminium, so they hold their shape when you wind them up tight.
Suits 3/8 inch and 10mm. Works with both 3/8 inch and 10mm axles, so check which size your rear hub runs.
Two axle positions. Two positioning options let you use the full range of the dropout when you set your wheel.
Four anodised colours. Anodised in black, blue, gold or red, with a laser etched MCS Bicycles logo.
