Elite-level aluminum wheels for DH/freeride.

Massively different: simple and beautiful, the unique wheel design is based around principles of strength, stiffness and acceleration.

Faster to accelerate: low rotational inertia. Unique wheel design distributes mass closer to the hub for faster acceleration and deceleration.

Tubeless-ready, hole-less rims: stronger and no rim tape required for tubeless setup.

Stronger and stiffer: Twinpair spoke technology. Designed using the strongest shape in construction, the triangle, to maximize strength and stiffness.

Beautifully simple, single spoke length: easy to true and replaceable without removing tire.

Tubeless Rim/Tire Cross-Section

Tubeless-ready rims are compatible with both standard and tubeless-ready tires. When a tubeless-ready tire is mounted on a tubeless-ready rim with special tubeless rim tape, valve, and sealant, the tire and rim form an airtight chamber that no longer requires a tube. This lets you run lower tire pressure with less fear of pinch flats and without the added weight of a tube. Lower tire pressure has many benefits, including greater traction and lower rolling resistance over rough surfaces. The rim can always be used with a tube, as well, by simply removing the tubeless valve stem and installing a standard tube like you would with any non-tubeless tire.
