Specifications

Q: Will this fit my Shimano Ultegra R8000 / Dura-Ace R9100 crankset?

A: Yes, this chainring is designed for the Shimano 110 BCD asymmetric 4-arm standard used on those cranksets and many others. It is the perfect replacement or upgrade.

Q: Can I mix and match sizes, for example, a 50T outer with a 36T inner?
