The Shimano Ultegra FC-R8000 HOLLOWTECH II crankset showcases clear design traits from the DURA-ACE R9100 with its robust four-arm design. Despite its enormous stiffness, which ensures optimal power transfer, the R8000 crank is even lighter than its predecessor, weighing in at 674 g (50-34T). The spacing of the chainrings has been revised to create more clearance for the frame, particularly for the increasing number of road bikes with disc brakes. This significantly improves shifting performance in conjunction with the required front derailleurs. The large chainrings offer maximum stiffness with minimal weight thanks to SHIMANO's HOLLOWGLIDE technology, which features a hollow structure. This stiffness directly benefits the rider through high front shifting performance. The R8000 cranks are available in a gearing option of 50-34.
