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\nWith unique tooth profiles, mount and climbing aids allow chainrings a particularly soft and fast switching. So with them a shift under load easily. The chainrings have been specially tuned by climbing aids and can only achieve their superior shifting performance in the combinations provided by ALUGEAR\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 of drivetrains\n\u003cspan\u003eALUGEAR chainrings are the best choice if you are looking for a technologically sound chainring with a unique design and low weight\u003c\/span\u003e\n\u003cspan\u003eQuality Manufacturing -
