Tensioner Arm

Description

The Supre chain tensioner arm pivots around the bottom bracket axis for tensioning the chain. On conventional derailleur drivetrains, the chain tensioner arm hangs off the derailleur and is vulnerable, but in the Supre Drive, it's protected at the middle of the bike. In combination with our chain tensioner cartridge, this chain tensioner arm has an innovative design that produces constant chain tension in all gears.

The Supre tensioner arm is incompatible with current-day Raceface chainrings because these protrude inward. It is however compatible with NS Billet chainrings, Hope chainrings, older Raceface chainrings, and all other chainrings that don't protrude inward.

The Supre tensioner arm is compatible with chainring sizes from 30 to 34 teeth.
