Aerodynamic chainring made of structural carbon fiber with a glossy 3K finish. Single chainring with 58 teeth and a bolt circle diameter (BCD) of 110 mm, 4 arms, compatible with Shimano Dura-Ace FC-R9200 and FC-R9200-P, Shimano Ultegra FC-R8100 and FC-R8100-P, and Shimano 105 FC-R7100 cranksets.

Groupset compatibility: Shimano 11-12s, SRAM 11s, and SRAM AXS 12-13s. Not compatible with SRM Origin.

For mounting on Shimano Dura-Ace, Ultegra, and 105 12-speed cranksets, we recommend using the new specific X-Cover DA9200 1x kit.

Mounting on other Shimano 12-speed crank arms is possible with the X-Fix ROAD XS kit, available in various anodized colors.

Although equipped with an anti-drop profile, a chain guide is recommended when using derailleurs without a clutch or not designed for 1x use.

Please verify the maximum diameter (242 mm) before placing your order. 100% made in Italy.
