The QO RACE 54T Aero Outer Chainring is a premium component engineered for competitive road cyclists and triathletes who demand maximum efficiency, precision, and aerodynamic advantage. Designed specifically for high-speed racing environments, this 54-tooth chainring ensures exceptional power transfer and optimized gearing for maintaining momentum on flat sections and during time trials.
Manufactured from high-grade 7075-T6 aluminum using CNC machining technology, the QO RACE 54T offers an outstanding balance of low weight, high tensile strength, and superior resistance to fatigue. This aerospace-grade alloy ensures the chainring maintains structural integrity under peak torque loads while delivering crisp, reliable shifting even under the stress of racing conditions.
Its aerodynamic profile has been meticulously refined to minimize air resistance, featuring smooth transitions between teeth and chamfered edges that reduce drag and turbulence around the drivetrain. The result is enhanced speed retention and improved pedaling efficiency in solo efforts or during high-speed peloton riding.
Optimized for use in a 2X drivetrain setup, the QO RACE 54T is designed to pair perfectly with a 40T inner chainring, offering an ideal gear range for competitive athletes seeking both high-end speed and responsive shifting on rolling or mixed terrain. Whether chasing a personal best or a podium finish, this chainring is built to perform when every second counts.
