Shimano Ultegra FC-R8100 12-Speed Chainrings
The Shimano Ultegra FC-R8100 12-Speed Chainrings are compatible with Shimano R8100 cranksets and other, 110 BCD 4-bolt cranksets. The aluminum construction uses Hollowglide technology to maximize stiffness while maintaining a low weight. They are available in 46/36, 50/34 and 52/36 sizes and are intended for use with Shimano 12-speed groupsets.
Please note the 46T chainring uses a flat profile and therefore requires specific bolts that match the profile of the crank arm.
