Description

The ROTOR QX1 chainring features a specific 12.5% ovality that makes it extremely efficient.

Indeed, it makes better use of the legs' strengths and weaknesses during rotation, engaging the muscles for longer during positive work and thereby reducing negative work. Your pedalling is rounder and more efficient!

The OCP system allows you to adjust the chainring position according to your physiological preferences, and to set the crank angle (+/- 5°).

Its design also ensures excellent chain retention, even without a chain guide.
