Carbon-ti X-Aeroring chainring

Aerodynamic structural carbon sprocket with 3K polished finish. The optimisation of the crowns for very high speed racing is achieved with the Full Carbon single crowns, which have been in use for two seasons on the UAE Team Emirates time trial bikes. X-Aeroring: single chainrings made entirely of carbon fibre. The aerodynamic profile, tested in a wind tunnel, ensures low drag, while the narrow-wide anti-fall tooth profile guarantees reliability and low friction. The chainrings must be run in with a new chain, as clean and lubricated as possible.
Carbon-fibre toothing requires more care to achieve satisfactory durability. Check the maximum overall diameter (242 mm) before ordering. For greater reliability, the use of a chain guide is recommended.
