Using our experience and vigorous testing, we 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\nThe 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\u003cbr\u003eA 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.\nThe tooth profile is specially designed for use with Road and MTB chains\nALUGEAR chainrings are the best choice if you are looking for a technologically sound chainring with a unique design and low weight\n\n\u003ch4\u003e\u003cstrong\u003eRECOMMENDATIONS\u003c\/strong\u003e\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003e\nWe recommend
