Why We Like The Ultegra FC-R8100 Crankset

Shimano's Ultegra FC-R8100 Crankset delivers the precise, responsive shifting action we're accustomed to, but with a wider range of crank arm length options. This makes for a crank that caters to everyone from smaller riders to triathletes. This crank features an optimal blend of stiffness, strength, and weight, but also rotational performance, and its Hollowglide structure makes for improved power transfer and quicker, more precise front shifting. The Ultegra FC-R8100 Crankset builds on Shimano's dedication to transmission efficiency, and it makes for front shifting that's hard to beat.
