We are excited to announce the addition of X-Aeroring chainrings to the Carbon-Ti range, developed and tested by UAE Team Emirates to compete and win in the most important races of the World Tour circuit.

The optimization of the chainrings for high-speed competitions is achieved using Full Carbon single chainrings, used for two seasons on the UAE Team Emirates' time trial bikes. X-Aeroring: single chainrings made entirely of carbon fiber. The aerodynamic profile, wind tunnel tested, ensures low drag, while the narrow-wide tooth profile prevents chain drops, ensuring reliability and low friction.

The chainrings must be broken in with a new, clean, and lubricated chain. The carbon fiber teeth require extra care to achieve satisfactory durability. Please verify the maximum diameter (242 mm) before placing your order. For greater reliability, we recommend using a chain guide.

X-Aeroring chainrings are available only on request in 58, 60, and 62 tooth sizes for Shimano 12-speed cranksets.
