Description

The ALUGEAR AERO Cover is designed for ALUGEAR 1X and 2X chainrings used with Shimano Ultegra R8100 12-speed cranksets. Its design conceals the junction between the chainring and the crank arm to achieve a more uniform and refined finish.

Made from 7075-T6 aluminium, this cover benefits from CNC machining and an anodised finish. Weighing just 17 g for the cover, it offers a lightweight solution while maintaining a design specifically adapted for the Shimano Ultegra R8100 crankset.

The system uses a 110 mm asymmetric Shimano chainline and a 4-arm spider attachment. Available in several anodised colours, it can be easily removed and refitted. It comes with 4 ALUGEAR M8 11.5 mm bolts and their spacers.
