Alugear Upgrade Aero Kit (Ultegra R8100)

Seamless Integration. Aero Perfection.

The Alugear Aero Upgrade Kit is CNC-machined from lightweight 7075-T6 aluminum to perfectly match the contours of the Shimano Ultegra R8100 crankset. By filling the recessed gaps between the crank arms and the chainrings, it smooths airflow across the drivetrain and provides a clean, "stealth" aesthetic that elevates any high-end road build.

Why the Aero Upgrade Kit is a Must-Have:

• Precision CNC Machining: Crafted with extreme tolerances to ensure a flush, rattle-free fit that looks like a factory-integrated component.

• Optimized Aerodynamics: By eliminating the turbulent air pockets typically found around chainring bolts, this cover helps reduce drag at high speeds.

• Sleek, Unified Aesthetic: Transforms the look of your crankset from a standard component into a piece of high-tech "cycling jewelry" with a smooth, continuous surface.

• Lightweight Performance: Despite its solid appearance, the use of aerospace-grade aluminum ensures that the kit adds negligible weight to your drivetrain.

• High-Durability Finish: Anodized in a deep black to perfectly complement the Ultegra R8100 finish and resist scratches from road debris.

• Easy Installation: Designed to fit perfectly with Alugear 2x chainrings, utilizing high-quality mounting hardware for a secure, "set it and forget it" setup.

Technical Specifications:

• Compatibility: Shimano Ultegra R8100 (2x12Speed)

• Material: CNC-machined 7075-T6 Aluminum

• In the Box: Aero cover and specialized mounting bolts

The Alegro Perspective: If you’ve invested in a high-end aero road bike like a SCOTT Foil RC, the small details matter. Standard chainring bolts look "unfinished" on a modern aero frame. This Alugear kit is the "pro secret" to making an Ultegra crank look even more high-end than a stock Dura-Ace setup. It turns your drivetrain into a single, cohesive unit that looks as fast as it feels.
