The Shimano Ultegra FC-R8000 HOLLOWTECH II crankset with its powerful four-arm design clearly shows the genes of the DURA-ACE R9100. Despite its enormous rigidity, which ensures optimum power transmission, the new R8000 crank is even more reserved than its predecessor on the scale (674 g, 50-34 Z). However, the chainring spacings have also been revised and slightly increased in view of the ever-increasing number of racing bikes with disc brakes. This creates more space for the frame and - in conjunction with the new derailleurs that are absolutely necessary for the new cranks - significantly improves shifting performance. With SHIMANO's HOLLOWGLIDE technology, the large chainrings offer maximum rigidity and low weight due to the hollow structure. This stiffness benefits the rider directly through the high shifting performance at the front. The R8000 cranks are available here in the 50-34 ratio variant.
