Take the bottom bracket cups and install them on the frame.
Tighten them to 39-40 Nm.
Place the spindle through the bottom bracket to install the right crank arm.
Add the left crank arm onto the spindle.
Ensure that there is no play and that the crank rotates freely by tightening the crank arm fixing bolt down.
Tighten the pinch bolts to 8-10 Nm and the crank arm fixing bolt to 12-20 Nm.
You can determine the number of spacers you need for the bearings if you take a quick look at the torque numbers.
