absoluteBLACK Premium Bolt Covers

These absoluteBLACK crank bolt covers are designed specifically for Shimano Dura-Ace 9100 series and Ultegra 8000 series 4-bolt, 110 BCD cranksets (they also work nicely with Rotor chainrings). These covers are beautifully machined from 7075-T6 aluminum and cover the small “step-down” between the absoluteBLACK oval rings and the crank arms. While these covers work aesthetically to complete the entire look of the crank, they also include the longer bolts needed when mounting the large absoluteBLACK rings to these Shimano cranks. Available in black or grey to perfectly match either the Dura-Ace or Ultegra crank colors, the bolt cover set weighs in at 13 grams and includes 4 covers and 4 long T30 torx crank bolts.

The grey color is Ultegra 8000 specific, while the black version is designed for Dura-Ace 9100 series cranks. These bolt covers will not work with subcompact oval rings.
