Shimano Ultegra FC-R8100 Crankset

The Shimano Ultegra FC-R8100 Crankset is an essential component of the Shimano Ultegra 12-speed road lineup, offering improved front shifting and transmission efficiency. This crankset has been refined to deliver seamless 12-speed shifting, and is now available in a wide range of lengths to provide better fit and performance for smaller riders, triathletes, and cyclists with specific biomechanical requirements.

Boasting an optimal balance of stiffness, strength, weight, and rotational performance, the FC-R8100 crankset features a Hollowglide structure that reduces weight while maintaining strength for better power transfer and more precise front shifting. With a 148mm Q-factor and a 44.5mm chainline, this crankset is designed to provide a perfect fit and maximum performance.

The Shimano Ultegra FC-R8100 crankset is also backwards compatible with 11-speed drivetrains, making it an upgrade from the Ultegra FC-R8000 crankset and interchangeable with 11-speed systems.

At, we offer a wide selection of Shimano Ultegra cranksets and other high-quality bike accessories, parts, and components. Shop with us online for the best selection and service in North America.
