Information

Engineering excellence

ALUGEAR chainrings are some of the lightest chainrings on the market. Using our experience and vigorous testing, we tweaked the arm design and strategically machined the chainrings so that only minimal sacrifices were made in impact strength in exchange for large gains in weight reduction. With special tooth profiles, ramp and climbing aids allow the chainrings particularly soft and fast shifting. So with them, shifting under load is easy. The chainrings have been specially tuned by climbing aids and can only achieve their superior shifting performance in the combinations provided by ALUGEAR. The chainrings are CNC machined from 7075 T6 aluminum and hard coat industrially anodized to provide protection from mechanical impacts, a good look, and an excellent tactile feel to each of the chainrings that lasts a long time.
