Shimano 105 FC-R7000 Crankarm

The FC-R7000 left crank arm is designed specifically for the Shimano 105 R7000 series. While it uses the standard Hollowtech II interface, we recommend sticking to the R7000 series to ensure perfect aesthetic and mechanical alignment with your existing drivetrain.

Yes, this replacement arm includes the necessary pinch bolts required to secure the crank arm to the spindle. You will not need to purchase additional hardware for installation.

Crank length is typically printed on the inside of your current crank arm near the pedal threads. If you are replacing a damaged arm, it is critical to match the length of your existing crank to maintain your current fit and pedaling geometry.

While the Hollowtech II interface is shared across many Shimano road cranks, mixing series—such as using a 105 arm on an Ultegra or Tiagra crank—can result in slight differences in finish, weight, or Q-factor. For the best performance and look, it is best to replace like with like.

You will need a Shimano Hollowtech II preload tool to tighten the plastic adjustment cap and a 5mm hex wrench to tighten the two pinch bolts on the crank arm. Ensure you follow the torque specifications printed on the component to avoid damaging the spindle.
