Ride the lightness.

The weight competition between common mountain bike frames, drivetrain components, saddles, bars, and the like is pretty close — a few grams here and there separate the Clydesdales from the pencil necks. With the AX-Lightness Premium 27.5in Tune Hub Wheelset, though, you're talking a few hundred grams between them and their closest competitors. If your aim is to ride lightness, then these are your wheels.

Importantly, the claimed weight of just 1,175 grams for the set doesn't come at the cost of safety. Every step of these wheels' lives — from conception to cutting carbon to the final stages of curing — takes place under one roof in Creußen, Germany. After all the fancy CAD software testing and whiteboard doodling is over, the material process begins with a carbon weave. AX uses a weave because, unlike the ubiquitous unidirectional fibers, a woven fabric has multi-angle load bearing properties that recommend it for a wheel's rim, which experiences dynamic directions of pressure as it spins. This means efficient power transfer and torsional stiffness can be achieved with less material, which in turn results in less weight.

The wheels' reliability is boosted by AX's Spoke Reinforcement Technology, which creates the spoke holes during the manufacturing process itself. There is no post-production drilling once the rims come out of the autoclave, so there's no additional structural weakness. As a result, the Premium 55Ts can bear five tons of nipple resistance, which AX-Lightness takes advantage of by tensioning the spokes to 1300 N. The hubs are provided by Tune, a boutique manufacturer in Germany's Black Forest. The flanges are reduced and wrapped in carbon, which makes for a lighter overall unit that doesn't sacrifice stiffness.

Please note that AX-Lightness recommends a rider weight limit of 220 pounds/100 kilograms.
