Shimano’s all new Ultegra FC-R8100 crankset has been engineered and designed to strike the perfect performance to price balance. The R8100 shares the same modern and sleek design language of it’s big brother the Dura-Ace R9200 crankset. Its Hollowglide construction sheds unnecessary weight without affecting stiffness, resulting in maximum power transfer and peak efficiency. Just like the previous 11-speed generation, the new R8100 crankset utilizes the same Hollowtech II and 24mm spindle technology which makes upgrading to the new Shimano 12-speed systems a breeze. For the R8100 crankset Shimano have increased their crank length offerings in order to accommodate more riders' preferences. Add it all up and you’ve got a crankset that offers bleeding edge technology and top tier performance.
