ALUGEAR chainrings are some of the lightest chainrings on the market. Using experience and vigorous testing, Alugear 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.

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. A unique tooth profile eliminates chain noise, reduces wear, and provides smooth operation on the entire system of all the most common combinations, such as 10, 11, and 12-speed drives. The Narrow Wide teeth guide the chain reliably.

Compatibility:

• Fits 4-arm cranks with 104mm BCD.
• The tooth profile of the 30-38t. Chainrings specially designed for MTB chains.
• The tooth profile of the 40-48t. Chainrings specially designed for road chains.
• compatible chains for MTB: all 10-, 11-, 12-speed SRAM Eagle and Shimano
• compatible chains for road bike / gravel: all 10-, 11-, 12-speed SRAM, Shimano, Campagnolo

Recommendations:

• Alugear recommends the use of a clutch system rear derailleur for the best chain security.
• It is also a good idea to use a new chain with your new ALUGEAR chainring.
• For mounting the 30 tooth chainring 8mm screws (M8) are required. The other chainring sizes require 6mm screws (M6)
