Ultegra FC-R8100 Chainring
Description
SHIMANO 2/12-speed chainring for Ultegra FC-R8100 crankset and Ultegra FC-R8100-P cranks with powermeter. While the inner chainring is made of anodised aluminium, the outer chainring has been hollow-formed (Hollowglide) from anodised aluminium and carbon fibre-reinforced composite to save weight. This results in first-class stiffness values and high durability.
