The Aksium's combine Mavic's renowned value, reliability, and obsessively developed French engineering into a wallet friendly package for those of us on a budget. While it doesn't go toe-to-toe with the top-end wheels found in the peloton and on local start lines, it makes for a solid set of training hoops for those of us wanting to save the pricier wheels for race day or a notable upgrade over most stock wheels for cyclists who simply want a reliable, affordable wheelset. The Aksiums are notably less expensive than Mavic's Ksyrium wheel offerings, which is the result of a series of minor omissions. For example, rather than having FORE drilled rims and thread-in spoke grommets, the rim is a more traditional single-eyelet-style, with the spoke holes penetrating the outer wall of the rim. These are definitely not race rims, but they're absolutely fearless in the face of training miles over chip seal asphalt and shoulders littered with spring run-off. The Aksium's rims are constructed from S6000 aluminum, and Mavic uses its UB Control technology to mill the braking surfaces of the rim for improved brake friction and smoother, more controlled stopping in almost any weather conditions. Both wheels feature 20 straight-pull, steel spokes with steel nipples. The hubs use Mavic's QRM double-sealed cartridge bearings to deliver high mileage and long-lasting dependability. Though the Aksium Wheels aren't as light as some costlier, heavily milled counterparts, their durability is outstanding at this price point.
