Shimano FC-R8100

The ULTEGRA FC-R8100 crankset performs two crucial functions: delivering the best possible power transfer from your pedaling to the drivetrain and providing the fastest, most precise shifting. On both counts, this new crankset won’t disappoint: thanks to the combination of the two best technologies on the market, HOLLOWTECH II and HOLLOWGLIDE, it achieves the optimal balance of stiffness, strength, light weight and rotational performance.
