Shimano Ultegra FC-R8100
The Shimano Ultegra FC-R8100 is a 12-speed road crankset with Hollowtech II construction and hollow-forged chainrings that balance stiffness, weight, and front-shifting precision just below Dura-Ace level. It suits road riders building or upgrading a 12-speed Shimano drivetrain, with 34/50 and 36/52 chainring options across a range of crank arm lengths.
- The ULTEGRA FC-R8100 crank performs two vital functions: transferring your pedaling effort into the drivetrain and ensuring the fastest, most precise front shifting available. Thanks to HOLLOWTECH II and HOLLOWGLIDE technologies, Shimano's class-leading chainring designs, the FC-R9200 strikes the optimal balance of stiffness, strength, weight and rotational performance.
