The new Shimano Ultegra R8000 line is finally here. It may be the next step down from the Dura Ace line 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.
