INFORMATION

• ALUGEAR chainrings are among the lightest on the market.

• Through experience and intensive testing, the arm design has been optimized, and the chainrings are CNC milled, so that only minimal compromises in impact strength are necessary for significant weight reductions.

• CNC milled from 7075 T6 aluminium and industrially hard-anodized for protection against mechanical impacts, long durability, and an excellent tactile feel.

• Unique tooth profile eliminates chain noise, reduces wear, and ensures smooth operation in all common systems (10, 11, and 12-speed). Narrow Wide teeth reliably guide the chain.

• The tooth profile is specially designed for Road chains.

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

RECOMMENDATIONS

• We recommend using rear derailleurs with a clutch system for optimal chain security.

• It is also a good idea to use a new chain together with your new ALUGEAR chainring.
