Alugear Narrow Wide Road Chainring - for SRAM Apex 110 BCD Asymmetric - 4-Bolt

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.
