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.

Update: We already updated the clincher hooked rim to clincher hookless rim since October 31, 2014.
Most of rims specifications are the same between hooked and hookless rims. But there are slightly different, especially for the ERD and the inner width.


MTB 27.5″ rim specially for AM & XC racing,tubeless-compatible


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


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.


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.


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.

Jano : It's my cannodnale scalpel 27,5 with LB's rims, handlebars and seatpost. I put rougly 3000 km onroad and offroad onto these wheels and i have to tell you that the rims seems to be perfectly ok so far and they look even better :). Haven't have any problems since i built them and hopefully there wont be any problems with them. I will probably place one more order for mtb carbon frame 27,5 and another set of the rims.

Hi i just bought a pair of LB AM 40mm rim from my local guys (AGS MTB), i'm lacing it to Chris King ISO hub. Whats the spoke length for 2x lacing? thank you.


Light-Bicycle 2016/10/31

Hello Jeremy, Thanks for your support! Due to the complexity and variations with calculating spoke lengths, we cannot guarantee the spokes will be the perfect length for your wheels.It will be great if you confirm the spokes length with your own builders. Thanks, Light-bicycle

Good Afternoon, I kindly ask if it's possible to buy rims, spoke and nipples. I have a pair of dt 240 hub 32 holes (not straightpull), so my idea Is to buy rims, spoke and nipples and assemble myself. Could you give me an idea of the total amount of the order? kind regards


Light-Bicycle 2016/06/12

Hello Stefano, Sorry for the late reply. We were on the vacation in last 3 days (Dragon Boat Festival). It is okay to buy the rims/ spokes/ nipples to build the wheels by yourself. Which spokes and nipples do you like? We can quote accordingly for you. Thanks, Light-bicycle

Adrien 2016/03/09

Hi, Are the spokes holes asymmetricaly drilled ? Is it possible to order theses rims without internal drilling like mavic's UST rims ? Thank you, Adrien


Light-Bicycle 2016/03/10

Hello Adrien, Thanks for your inquiry. These rims can not be drilled with UST version. Because it is not deep enough for nipples to go through inside while building wheelset. Our 34mm width asymmetrical rim can do UST if you like. Thanks, Lightbicycle
