Smoother Pedalling Through the Power Phase

Overview

The Rotor Q39T For 53,52,46 BCD130x5 Inner Chainring uses an oval profile that follows the natural variations in the pedal stroke. It helps deliver power more efficiently through demanding road efforts.

Adjustable OCP Positioning: Five Optimum Chainring Positions allow riders to adjust the ring orientation according to their pedalling style. This supports a more personalised balance between power delivery, cadence and comfort.

Precision Aluminium Construction: The chainring is CNC-machined from durable 7075-T6 aluminium for dependable stiffness and accurate operation. Its lightweight construction suits performance road and triathlon bicycles.
