Chainring for the Shimano Ultegra FC-R8100 and FC-R8100-P 2x12-speed cranksets.

The chainrings with 110 mm bolt circle diameter ensure fast as well as smooth shifting. For reasons of weight optimisation, the outer models also feature a Hollowglide construction, which can still come up with an extremely stiffness.
