INFORMATION

ALUGEAR chainrings are among the lightest on the market. Through experience and extensive testing, we have optimized the spoke design and strategically machined the rings, significantly reducing weight without any significant loss of strength.

The special tooth profiles, mounting surfaces, and shifting ramps provide smooth and fast gear changes – even under load. The chainrings are carefully matched to the combinations recommended by ALUGEAR to achieve the best shifting performance.

The chainrings are CNC-machined from 7075 T6 aluminium and industrially hard-anodized, providing resistance to impact, a great look, and a long-lasting finish with a premium feel.

The unique tooth profile minimizes chain noise, reduces wear, and ensures smooth operation on all common gear systems. The profile is designed specifically for road chains.

ALUGEAR chainrings are the best choice if you want a technically advanced chainring with a unique design and low weight.
