Add Valve Stem USD +7

We include enough valves to cover your individual rim purchase. We use a lightweight black alloy anodized valve with an oversized concave collar for easy gripping. A rubber o-ring goes in between the rim and the collar to help seal the rim and match the contour of the rim profile. The vavle core is removeable so you can add sealant withoutn removing your tire.

Tubeless Tape This is a required option.

None

Add Tubeless Tape USD +6

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.

MTB carbon rim profile

Teleport to the rim page.

The wheels use an easy to set up tubeless system complete with bead retention that still allows for quick tire changes. Of course you can still use tubes as required.


From all day epics and marathon events to hard charging short track XC racing, these wheels have a huge performance edge over wheelsets in this weight and price category. To achieve this kind of weight with an alloy wheelset, you have to make sacrifices to rim strength or width, stiffness, and build strength.

Cuopon code (USD90.00 off per wheelset): VK4RMA7N

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, 15 Months Warranty
For Pro Series Rims: From the date of purchase, 3 Years Warranty. Light Bicycle is pleased to offer the options to purchase an extended 5-year Premium warranty or lifetime Premium warranty with minimum charge respectively.

Crash Replacement: It is applicable with the same period as to warranty time range that you purchased for the rim in terms of 15-month/ 3-year/ 5-year/ Lifetime, with 10%+ discount subject to rim model.

Tony 2017/12/08

Hi,what type of carbon wheel set would you suggest for me I race in cross country events in new zealand.


LightBicycle 2017/12/09

Hello Tony, Thanks for your inquiry! We have 29er 27mm wide standard/flyweight rim and 28mm wide asymmetric rim for XC riding. May I know your weight? Do you ride aggressively? Then we will do some recommendations. DT 240S hubs and Sapim cx-ray spokes are the lightest hubs and spokes we have here. Does that work for you? What hubs axle size for front and rear? Thanks, Lightbicycle
