Part of the new 12-speed road bike series, the FC-R8100 crankset benefits from the legendary chainring shifts and overall efficiency of the Shimano drivetrain. With new enhancements for even smoother gear changes in the 12-speed system, the Ultegra crankset is now offered in lengths ranging from 160 to 175 mm to boost performance and provide a better fit for smaller riders, triathletes, and those with specific positioning needs.

• Optimal balance between stiffness, resistance, weight, and torque performance
• The HOLLOWGLIDE structure reduces weight while maintaining stability for better power transfer and faster, more precise front shifts
• Chainring combinations of 52-36, 50-34, and 46-36 teeth. Crank arm lengths of 160, 165, 170, 172.5, and 175 mm.
