The Rotor Q Rings Aero 53T BCD110x4 Outer Chainring uses an oval profile to reduce the effect of weaker points in the pedal stroke. This supports smoother pedalling and more efficient power delivery during road efforts.

Aerodynamic Outer Profile: Its aero-style outer surface creates a clean, streamlined appearance around the crankset. The design suits performance road, time-trial and triathlon bicycles where efficiency and integration are important.

Precision Aluminium Construction: The chainring is manufactured from lightweight aluminium for dependable stiffness and accurate shifting. Its rigid structure supports efficient power transfer during accelerations, climbs and sustained high-speed riding.

Designed for 53/39T Setups: The 53T outer ring uses a four-bolt 110 mm BCD interface and is designed to pair with a compatible 39T inner chainring. It supports suitable 11-speed ROTOR cranksets and compatible BCD110x4 systems.

Rotor Q Rings Aero 53T BCD110x4 Outer Chainring for 39T Inner offers aerodynamic styling, smooth pedalling and performance-focused road compatibility.
