Ideal for time trials

Aerodynamic structural carbon chainring with 3K gloss finish. Single 58-tooth chainring with 110 mm bolt circle diameter (BCD) and 4 arms, compatible with SRM Origin crankset. Compatible with Shimano 11-12s, SRAM 11s, and SRAM AXS 12-13s groupsets.

Extremely high speed
The optimisation of chainrings for extremely high-speed competitions is achieved thanks to Full Carbon single chainrings, which have been used for two seasons on 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-drop 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 teeth
Carbon fibre teeth require greater care to achieve satisfactory durability. Check the maximum diameter (241 mm) before ordering. For greater reliability, the use of a chain guide is recommended.
