Delivery estimate

The Rotor 55T BCD144x5 1/8" Round Chainring is designed for track and fixed-gear bicycles requiring high-speed gearing. Its 55-tooth size supports strong acceleration and sustained cadence during fast efforts.

Consistent Power Delivery: The conventional round profile provides predictable resistance throughout every crank rotation. This familiar pedalling feel helps riders maintain a smooth rhythm during training, racing and high-intensity sessions.

Precise Aluminium Construction: The chainring is precision-machined from aluminium to provide the stiffness needed for direct power transfer. Its anodised finish adds durability while maintaining a clean, performance-focused appearance.

Dedicated Track Fitment: The five-bolt 144 mm BCD interface fits compatible track cranksets, while the 1/8-inch tooth profile is designed for suitable single-speed and fixed-gear chains. Correct drivetrain compatibility should be confirmed before installation.
