Sapim Race – Our strongest and stiffest spoke. These spokes are suitable for heavy or extremely aggressive riders who need a stiffer wheel.
Sapim CX-Ray – The lightest spoke in our lineup is still quite strong due to the elasticity and amazing fatigue life.

DT Competition Race - All Mountain and XC spoke used by the Chinese location as a substitue for the D-Light (depending on availability)

Pillar PSR X-TRA 1420 - An inexpensive bladed spoke, great for road and cyclocross riding.

One 10 yard roll of tape will be included. It is typically covers 2 rims with two laps each or 4 rims with one lap each.The high tensile tubeless tape features a natural rubber adhesive that does not leave a residue on the rims. On mountain bike rims, one layer of 18mm width tape is strong enough to seal the access holes which makes for the lightest tubeless setup.

Teleport to the rim page.

Our 34mm wide AM728 rims have become our most popular asymmetric product thanks to its versatility. The 28mm inner width offers a wide and stable tire profile for your enduro tires, without becoming square-edged. You can easily get away with running 2.2’s or 2.5’s, but 2.3” - 2.4” tires are the sweet spot. The EN version has an extra wrap of 3k carbon fiber around the nipple bed, and reinforced sidewalls support G-Out forces, and increased rim stiffness, increasing suitability for aggressive riders over 200 pounds.


More air volume, a wider stance, and the bead seat retention system will keep your tires in place on race day and provide an incredibly solid tubeless platform. Wheel stiffness is further increased with a deep profile, allowing for cornering and charging through rough terrain with more speed and confidence than ever before.

Hookless: Carbon fiber flows continuously over the bead area to provide the best impact resistance and a significant strength increase compared to a clincher rim.


Manufacturing process: Our air bladders are made from a special material which produces smoother walls, result in a lighter rim, and are completely removed without harsh chemicals. They are removed through the valve hole with a unique process so that the rim does not have to be patched like traditional manufacturers use. This significantly improves the strength of the rims. Read More about our process


Hand-Built: Each wheelset is painstakingly built by hand to tension within 5% variance. Each spoke's tension rating is recorded in our system, as is the roundness and lateral tolerance.


T700: Constructed with premium Toray T700 carbon fiber. The best strength to weight ratio with no expense spared.


Precise layup: Each rim carries its own layup schedule documents which are followed meticulously by the layup workers. Our Engineering team creates a unique fiber orientation which amplifies the desired riding characteristics for a given rim.


Angled Holes: Angled spoke holes allows the nipple to pull straight in line with the spoke for reduced stress. This results in fewer broken spokes and nipples.


U-Shape: U-shape profile spreads the force of impacts and creates a more robust product.


Bead lock: The small ridges on either side of the drop channel help secure tubeless tires in place. The bead lock makes it easier to seal up tubeless tires with a floor pump, and they are incredibly hard to burp.


Asymmetrical: The profile allows for equalized spoke tension which creates a stronger wheel that stays true.


Tubeless: While the rims are optimized for a tubeless setup with the addition of tubeless tape, they also work with tubes.


For Non-Pro Series Rims: From the date of purchase, 3-year Standard Warranty.

For Pro Series Rims: From the date of purchase, 5-year Pro Warranty as standard and an upgraded optional lifetime Premium Warranty with minimum charge.

Crash Replacement: It is applicable with the same period as the warranty time range that you purchased for the rims with 10% /25% discount for Non-Pro series /Pro series.
