Shimano Ultegra FC-8100 Outer Chainring
Shimano Ultegra FC-8100 Outer Chainring Info
The Shimano Ultegra FC-8100 Outer Chainring is a direct replacement ring for Shimano's 12-speed Ultegra crankset, built from aluminum with an anodized finish for a balance of low weight and long-term durability. Hollowglide tooth profiling — a design feature shared with Dura-Ace — is intended to improve chain pickup and front shift precision across the full gear range.
The asymmetric 110 BCD mounting pattern is specific to Shimano's current 12-speed road groupsets, so fitment is straightforward if you're running an FC-R8100 crank. Available in 50t and 52t, the ring covers the most common gearing choices for road riding, whether you're targeting long climbs or fast group rides where a bigger gear pays off.
