Elsier Chainring 144 BCD Track Bike Fixie Aero Fixed

The Elsier 144 BCD Chainring is designed for track bikes, fixed-gear bicycles, and single-speed builds where reliable chain engagement and efficient power transfer are important. Made from AL-7075 aluminum alloy and CNC machined for precision, this chainring combines a lightweight construction with the stiffness needed for demanding cycling applications. Its aero-style profile gives the chainring a clean, performance-focused appearance while supporting efficient drivetrain operation. The 144 mm BCD makes it suitable for compatible track and fixed-gear cranksets designed around this bolt pattern. The chainring shown features a 46-tooth configuration, with precise CNC-machined teeth for consistent chain engagement. Marked as Made in Taiwan, it is a practical upgrade for riders building or refreshing a track, fixie, or single-speed drivetrain.
