Shimano Ultegra FC-08 Crankset

Yes, the FC-08 is specifically optimized for 11-speed drivetrains. It is designed to integrate seamlessly with standard 11-speed setups to ensure precise and responsive shifting.

This crankset uses an outboard bottom bracket interface. You will need a compatible Hollowtech II or equivalent outboard bottom bracket shell to install it correctly.

Yes, this crankset features a 4-arm chainring mount with a 110mm bolt circle diameter (BCD). This allows you to replace the chainrings when they wear out or if you need to change your gearing ratios.

The Hollowtech forged arms reduce the overall weight of the crankset without sacrificing stiffness. This reduction in rotating mass helps improve acceleration and power transfer, making the bike feel more responsive under load.

The Q-factor is 146mm. This measurement represents the distance between the crank arms, which affects your stance width while pedaling; 146mm is a standard road racing width designed to balance efficient power delivery with rider comfort.
