SRM Origin Road 11S Aluminum Chainrings

This SRM Origin Road 11S Aluminum Chainrings come standard on new SRM power meters and we also offer it sold separately for customers who want to make a change to their chainring size. The chainrings are made from 7075-T6 aluminum and is anodized for additional strength and durability. It is lightweight, strong and offers crisp shifts, even under load. We have found it to perform beautifully on the SRM or any other crankset that uses the 110 BCD 4-bolt asymmetric pattern. In addition, it’s offered at a fraction of the price of many other chainrings.


  • Compatible with 110 BCD, 4-bolt cranksets
  • Works with 11-speed drivetrains
  • Inner chainring weight: 39 grams (34T)
  • Outer chainring weight: 173 grams (50T)
