As a key component in SHIMANO's new 12-speed road bike lineup, the FC-R8100 crankset is characterized by SHIMANO's signature shifting quality and transmission efficiency. Redesigned for seamless 12-speed shifting, the ULTEGRA crankset is available in lengths from 160 to 175 mm. This translates to increased performance and improved adjustability for smaller riders, triathletes, and riders with specific biomechanical needs.
