The simplified one-piece design saves approximately 40 grams compared to standard ring+spider+bolts combination (for example, weight savings for a 32t ring is 40g). By machining our direct mount chainrings from a single piece of aluminum, in addition to trimming weight, rigidity gets improved by orienting the aluminum’s unidirectional fibers to take maximum advantage of their properties.</p>https://rotorbike.com/catalog/media/catalog/product/c/0/c01-036-29010-f01-700px_1.jpg79.99instock79.9979.9900000https://rotorbike.com/catalog/media/catalog/product/c/0/c01-036-29010-f01-345px_15.png/ROTOR/ROTOR/MTB | XC / MARATHON/ROTOR/MTB | XC / MARATHON/Plateaux/ROTOR/MTB | XC / MARATHON/Plateaux/Plateaux Ovalises/ROTOR/MTB | XC / MARATHON/Plateaux/Plateaux Ovalises/Direct Mount
