SRM CYBREI METARBON Aero 110×4 Chainrings

The SRM CYBREI METARBON Aero 110×4 Chainrings are made from carbon fiber with 7075-T6 aluminum teeth, making them lightweight, durable and precise when shifting. Their engineered design maximizes stiffness, aerodynamics and power transfer for maximum performance. In addition, the aero profile reduces drag by smoothing airflow around the crankset. This saves you watts when you need them most!

The Universal Version chainrings fit both SRM PM9 Origin Road 110×4 BCD power meter spiders along with other cranksets that use a 110×4 BCD interface. The SRM PM9 Version only fits SRM PM9 Origin Road 110×4 BCD power meter spiders.

They come in 50/34T, 52/36T and 54/38T sizes and are compatible with 11-speed drivetrains and 12-speed Shimano systems.
