Low weight, efficiency, and speed: That's what Shimano's Ultegra Crankset brings to every ride. The proprietary four-arm design sheds grams and increases stiffness for more power straight to the road. Computer-designed chainrings with optimally placed ramps and pins are a revolution in front shifting with fast, smooth gear changes that set the standard. A wide range of gearing options and crank lengths offers you the opportunity to find the crank that suits your riding style.
