HOW TO MOUNT ABSOLUTEBLACK BOLT COVERS:
Remove your current bolts and nutscompletely. 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 torxT30 sockets and screw them from the back. You should use about 5-7Nm of force.You MUST use medium strength thread locker on the bolt threads. (for eg.Loctite 243)
