How to mount absoluteBLACK bolt covers:
Remove your current bolts and nuts completely. Place the bolt covers into their specific positions from the front, so they sit nice and flush with crank. Then use provided short bolts with torx T30 sockets and screw them from the back. You should use about 5-7Nm of force.
IMPORTANT! While tightening the provided bolts to the recommended torque, it is necessary to prevent the bolt covers from spinning, by holding them down with your fingers. If the covers are not held while torqueing the bolts, they might get damaged.
