Rotor Q-Ring Qarbon BCD 110 53T chainring

8% lighter than aluminum alloy Q-Rings.

Engineered with CNC machining and aerodynamic design reinforced with high modulus 3K carbon fiber, which increases rigidity by 20%.

Reduces stress on the knees.

10% ovality increases efficiency and reduces fatigue over long distances.
