Upgrade the connection between your top-tier chainrings and crankset with the Carbon-Ti X-Cover AL7075 CNC Chainring Bolt Kit. This is a highly specific accessory designed for optimal compatibility with Shimano Dura-Ace FC-R9200/P and Ultegra FC-R8100/P 12-speed cranksets.
Crafted from high-strength AL7075 aluminum through precise CNC machining, these bolts ensure a robust and elegant connection for your X-Carboring EVO chainrings, translating to excellent power transmission efficiency. The complete set features 4 shaped females and 4 standard-length males, weighing in at a mere 23 grams.
Crucially, this kit is dedicated to double chainring mounting on the specified 12-speed models only; it is not compatible with older Shimano models like Dura-Ace 9100 or standard Ultegra/105. For mounting the X-Aeroring single chainring, please ensure you purchase the separate X-Cover DA9200 1X kit. Choose Made in Italy quality for your finest drivetrain components.
