Absoluteblack premium bolt covers aredesigned specifically for Shimano 110/4bcd Ultegra 8000 and Dura-Ace 9100cranks. They cover the small step down between chainring and crank arms,completing the entire look of the crank. With these covers your crank looksgreat again.


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



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)

Compatibility: Dura-Ace 9100, 9150 Di2,Ultegra 8000, R8050 Di2. (also fit nicely with Rotor chainrings). NOTcompatible with our Sub Compact chainrings

*Our aesthetic bolt covers are notcompatible with Sub Compact oval chainrings or Gravel and CX 1X ovalchainrings.
