INFORMATION

ALUGEAR chainrings are among the lightest on the market.
Through extensive testing and experience, the arm design has been optimized to reduce weight significantly without compromising on strength.

The chainrings are CNC-machined from 7075-T6 aluminium and industrially hard-anodized to provide long-lasting protection against mechanical wear, a great look, and a smooth surface.

The special Narrow-Wide tooth profile reduces chain noise, minimizes wear, and provides stable and smooth operation on all common systems, including 10-, 11-, and 12-speed.

ALUGEAR chainrings are the ideal choice if you want a technically advanced, lightweight, and stylish chainring.

RECOMMENDATIONS

• For the best look, you can use the ALUGEAR AERO COVER (for Ultegra R8000 cranksets).

• Use ALUGEAR bolts and nuts for mounting: 7 mm nuts and 6.5 mm bolts.

• Use a rear derailleur with a clutch system for optimal chain retention.

• Use a new chain with your new ALUGEAR chainring.

• Ensure the chain is always well-lubricated for every ride.
