praxis works wheels
Imagine how a bike mechanic would build their own set of wheels: strong, stable, responsive & serviceable.
Now, imagine that mechanic was also an engineer with the ability to design their own custom rim. Imagine one of the most trusted names in hubs, DT Swiss, was able to perfectly match their product to that rim.
Praxis works designed, studied, tested, built, and ridden what praxis works is ready to call their new wheels.
Praxis wheels come from decades of experience riding, racing & wrenching on two wheels, along with daily riding in Santa Cruz, California. They wanted a wheel which offered the benefits of modern materials and design, while using time tested technology. Like praxis works other innovative drivetrain elements, Praxis wheels let your bike do the work, and let you have the fun.

As technology pushes the limits of our equipment, the lines between DH, Trail, CX, and XC are blurring.
Praxis work's team set out to create rims which match the pace of development. These rims have ‘broad shoulders’ to support the wider tires popular in every discipline, giving you more support at the lower pressures tubeless tires allow. Combining those factors adds up to more control through the roughest terrain. Hookless carbon beads create a more resilient structure, at a reduced weight.
Stiffer, stronger, and ready to explore new trails. Praxis works studied a wide range of rim offsets, and determined a 3mm offset yielded a more stable wheel, without sacrificing rim design and strength. Praxis rims are designed to work with tubeless tires, and come pre-taped with valve stems installed. You’ll only need a floor-pump to ‘pop’-and-play.

Cliché as it may be, hubs really are at the center of your riding experience.
Hubs harness your power and maintain your speed, operating precisely while under extreme stress. Perfectly aligned rotor mounts and axle hardware is imperative for smooth, quiet braking – hardly a minor detail.
All Praxis wheels use DT Swiss hubs, which set the bar for dependability and performance.
Praxis by DT Swiss hubs are tailored to given lacing pattern, using DT Swiss 350 hub internals, and feature an upgraded 36 tooth Star Ratchet system from the box. DT products are supported throughout the world, so you can easily get parts to service or adapt your hub wherever you call home.

common sense innovation
One amazing thing about bikes is that they can be customized to every rider, with an endless array of options. Choosing the right combination of elements yields the best possible machine.
While praxis works wheels use standard elements, each is carefully selected to provide optimum performance.
This curated assembly allows them to be tuned and serviced over a lifetime of use, rather than rendered obsolete.
Praxis believes in products that give riders confidence, so they know their equipment will stand up when they throw down.
