About the MTB circle, we sell the most classic 30mm wide 25mm depth 29er mountain rims carbonbeam

The [CBZAXC30SL] rims blur the lines between XC race and All Mountain. The 25mm internal width can handle narrower 2.1” tires, but can also mount up to 2.4” with confidence when the trail conditions turn nasty. Whether attacking the climbs on technical XC courses on the weekend, or shredding the descents on your local trails mid-week, this rim is equally at home.

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. 

 

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+V-Shape: U+V-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.

 

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