Description
The Shimano Ultegra R8000 2 x 11 speed crankset is slightly heavier than the Dura Ace line crankset, but rest assured its technology is nothing short of unparalleled performance, designed to optimize input and maximize output. The R8000 11-speed 50x34T crankset is lighter than its predecessor, with a fatter profile for optimum stiffness and power transfer. A tapered crank arm and 4-bolt spider pattern seamlessly fuse together for a more streamlined, aerodynamic look. With the Ultegra R8000, no watt will be wasted.
