We carry SRM Chainrings made specifically for the SRM power meter. These rings are made from 7075-T6 aluminum and use SRM’s 110 BCD, 4-bolt pattern. They are also anodized for additional strength and durability. While not listed below, we also have chainrings from ROTOR and Carbon-Ti which use this same bolt hole pattern and work nicely with SRM power meters.
