Product Details

Mavic EN 821 Disc

Mavic’s EN 821 Disc rim is packed full of high-tech features that make it a savvy all-mountain trail partner. These include interspoke milling (ISM), a Mavic-patented concept that involves the machining of the lower bridge of the rim between each spoke hole to create a light, rigid rim while maintaining durability. This rim's asymmetrical shape allows for more balanced spoke tension, delivering a stronger, more reliable wheel. The EN 821 also features Mavic’s Fore design—instead of being drilled, the lower rim bridge is pushed up on the inside and threaded to enable special spoke nipples to be directly screwed in, leaving the upper rim bridge intact and resulting in a rim that is 4 times more resistant to fatigue stress and 20% more rigid. EN 821 rims are made of Mavic’s Maxtal alloy, which delivers weight savings and a 30% increase in rim durability over standard 6061 aluminum rims. Finally, Soudé Usiné Process (SUP) is a process by which the rim is arc welded and machined smooth, providing a stronger rim joint and better rim balance. All these features combine with a UST tubeless-ready design to make the EN 821 one of the finest, most versatile all-mountain rims available.
