Detailed product description

The patented CamClutch technology reduces chain movement while maintaining proper chain tension. Fitted in a carbon fibre and nylon composite construction, the clutch mechanism uses a clever, unidirectional friction plate which increases the tension as the cage moves forward, and reduces tension when the cage moves back towards the rear.

Pivot Tech
The patented Pivot Tech prevents damage in the event of a crash or side impact, by using a spring-loaded cable stop. Upon impact, the derailleur is allowed to turn inward, reducing the chances of it getting bent.
