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 (250mm) 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.
