*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. You MUST use medium strength thread locker on the bolt threads. (for eg. Loctite 243)

Simply put, these bolt covers for Ultegra and DuraAce cranks make your crank look even better with AbsoluteBlack or Rotor Oval chainrings. When you switch to Absoluteblack oval rings, you create a small step down at the connection point between crank arms and chainring bolt hole area.These bolt covers fix this making your crank look great again.

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. You MUST use medium strength thread locker on the bolt threads. (for eg. Loctite 243)
