Alugear Chainring - Road | 4x BCD 110 (Shimano Asymmetric / inside) | 2x 12s - round | black

Technologically solid, extremely light and unique in design. These properties characterize the chainrings from Alugear. And the inner chainring for 2x12-speed road bike cranks from Shimano is no exception.

Not only the wealth of experience of the Alugear engineers, but also extensive tests have contributed to a considerable weight reduction without having to make any significant compromises in terms of impact resistance. Both the optimized arm design and strategic machining of the CNC-milled aluminium chainrings are responsible for this. Smooth and fast shifting is not only ensured by special tooth profiles, but also by the mounting and climbing aids which facilitate gear changes under load.

Alugear chainrings are perfectly matched and only reveal their superior shifting performance in the combinations specified by the manufacturer. To improve the protective effect against mechanical impacts, the small chainring features an industrial hard anodization. The unique tooth profile also contributes to increased wear resistance. In addition, it eliminates chain noise to ensure smooth operation of the entire system.
