Stronglight Crono Time Trial Chainring 51T 10/11S 110mm

This chainring from Stronglight is designed for time trial and triathlon riders seeking maximum stiffness and optimal drivetrain efficiency at high speeds. Developed as a dedicated aero-focused ring and originally crafted for professional racing, it features CNC CT2 machining in 7075-T6 aluminum, ensuring a strong, precise profile that maintains its shape under intense efforts. The ceramic-teflon coating minimizes friction and wear for smoother operation in the big ring, while the 110 millimeter bolt circle makes it compatible with many popular 5-bolt road cranksets for 10- and 11-speed drivetrains. Supplied in presentation packaging, it’s a premium upgrade for fast, flat courses where maintaining power is crucial.
