Hole Count This is a required option.
Please note that our valves are drilled for presta and spoke holes are made for external nipples only. If you have a custom drilling requirements please e-mail us and we'll send you a purchasing link.
Finish This is a required option.
Matte is slightly lighter and a more subtle finish (most popular). Glossy has a shine to it.
Weave This is a required option.
The layup schedule is predetermined for each model, but you can choose the outer layer.
3k/12k/UD are the 3 choices for cosmetic appearance.The rim strength & weight is virtually identical.
UD Matte is the most popular and has a subtle look.
3k weave has a more traditional carbon fiber look.

Decal This is a required option.
The new graphics are included and available in 7 colors. The decals are now easily replaceable so you can keep your rims looking fresh.
Valve Stem This is a required option.
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.

Add Valve Stem USD +7 each
Tubeless Tape This is a required option.
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.

The Flyweight is a new series of rims from Light Bicycle. Targeted specifically towards racers who seek every possible edge on the race course. Our goal was to produce the lightest possible rim without sacrificing performance.
Drawing on our engineers’ years of experience and countless revisions in each step of the manufacturing process, we are able to produce a strong and stiff XC rim while dramatically reducing the weight.
Construction: We used a special uni-directional pre-preg with a very low fiber areal weight. This is an exclusive process to our Flyweight rims. To further reduce the weight we used a blend of Toray T700 and T800 specific layups. We opted for a new subtle ultralight waterslide graphic in glossy black with a matte finish overtop in the spirit of keeping these as true cross country race oriented rims.
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.

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.
Tubeless: While the rims are optimized for a tubeless setup with the addition of tubeless tape, they also work with tubes.
Material: Standard: Constructed with premium Toray T700 carbon fiber. The good strength to weight ratio with no expense spared.
Flyweight: Hybrid construction of Toray T800 and T700 was used to reduce wall thickness in key areas while enhancing the overall rim stiffness. These rims are available with the UD material only due to the strict standards required to produce the Flyweight model. We used a lower FAW (fiber areal weight) and a thinner prepreg to achieve a more adjustable layup schedule design which reduces the stress between the layers of carbon fiber.
Precise layup: Standard: 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.
Flyweight: New layup design at the nipple bed to reduce the amount of material required and reinforce the key area around the spoke holes.
Lightweight: Standard: It is the light one around our current 650B rims, the good choice for lightweight 650B wheels & bike.
Flyweight: It is a new series of rims from Light Bicycle. Targeted specifically towards racers who seek every possible edge on the race course. 270 grams only!
