INFORMATION

ALUGEAR chainrings are among the lightest on the market.
Using experience and thorough tests, we have optimized the arm design and strategically machined the chainrings to significantly reduce weight – without compromising on strength.

The unique tooth profiles and shifting aids ensure smooth, fast, and precise shifting, even under load.
The chainrings are optimized to function best in the combinations recommended by ALUGEAR.

The chainrings are CNC-milled from 7075-T6 aluminum and hard anodized, which protects against mechanical wear, provides an attractive appearance, and a pleasant surface that lasts a long time.

The special tooth profile minimizes chain noise, reduces wear, and ensures smooth operation on the most common gear combinations.
The design was developed specifically for road chains.

ALUGEAR chainrings are the ideal choice if you want a technically advanced, lightweight, and aesthetically beautiful chainring.
Proudly made in Poland.
