The Shimano Ultegra FC-R8100 crankset is precisely designed for outstanding shifting precision and power transfer to ensure a smooth and controlled ride. The FC-R8100 is part of Shimano's unique 2x12 speed series, and it includes 172.5mm cranks, as well as chain-rings that improve drive-train efficiency. The Hollowglide design on the outer chain-ring dramatically reduces weight while maintaining strength, resulting in better power transfer and faster, more precise front shifts.
The crankset incorporates Hollowtech technology, with hollow, lightweight forged cranks that reduce overall bike weight and allow for faster acceleration by lowering rotational mass. Furthermore, Hollowtech II technology incorporates an integrated bottom bracket axle into the right crank, providing improved rigidity and lightness for a high-performance ride. The FC-R8100 crankset has a tooth arrangement of 52/36, a BCD of 110mm, and a Q Factor of 148g, making it ideal for smooth gear shifts and long-lasting performance. Weighing in at only 700g, the crankset is the ideal combination of strength and efficiency, making it an important upgrade for professional cyclists looking to improve their riding performance.
