What sets the Shimano 105 FC-R7000 crankset apart?

The Shimano 105 FC-R7000 crankset is built around Hollowtech II, the hollow-forged aluminum crank arm and 24mm spindle design that balances stiffness, strength, and low weight for efficient power transfer. This is the 172.5mm arm in black, and it ships without chainrings so you can pick the 50/34, 52/36, or 53/39 combination that matches your riding. The four-arm asymmetric spider uses a 110mm bolt circle that accepts all three combinations.

Its wider gear pitch adds chain clearance with smaller gears and allows for shorter 410mm chainstays on 135mm rear-spaced frames, so it plays nicely with modern disc brake road bikes. It runs 11-speed HG-EV and HG-X11 chains and works across the 105, Ultegra, and Dura-Ace mechanical road families. Note that chainrings and the bottom bracket are sold separately, which makes this a clean starting point for a custom build or a crank arm replacement.
