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.

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 wheelset building page.

Built to handle the most technical trails on the mountain, the AM733’s 33mm internal width is a perfect fit for the new breed of ultra wide 2.4-2.8” tires. You’ll appreciate the confidence boost with the massive air volume, impressive traction, and bead seat bumps to keep those big tires in order.


Available in two layup styles, the standard layup is suitable for most riders, but if you are over 200 pounds or tend to ride your equipment really hard, consider the extra layer of 3k carbon in the EN version. Not only does this support G-Out forces, but it also makes the EN733 incredibly stiff and perfect for the hardest charging of riders.


E-bike Approved! This rim's Enduro Version is designed to be compatible with mid-drive e-bikes.

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.


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.

Can I get this with the glossy finish and custom decal? What is the additional cost? Also why is the offset 2.7mm compared to 2.0mm on your other rims? Thanks!


LightBicycle 2019/02/23

Hi James, Hi James, It is okay to make AM733/EN733 650B rims with glossy finish. Do you like UD glossy or 3K glossy? There is no additional cost. For custom decal, the cost will be around USD75~90 for 2 colors. May i know your graphic design sketch? Then we can quote accordingly for you. For 2.7mm on this rim, because it is wider rim than other rims. For wider rims, they can have bigger offset to get spokes more balanced between drive side and non drive side. Thanks, Lightbicycle

Igor 2019/02/02

Is this rim good for e mtb and also any special steps to calculate spokes length/build this rim ?


LightBicycle 2019/02/02

Hi Igor, Thanks for your inquiry! For AM733 rims(40mm outer/33.6mm inner) and AM740 rims(46mm outer/40mm inner), they are both good for E-mtb bike. May i know your tire width please? Then we can check which rim is better for you. Normally, we use heavy duty version for E-bikes. It is around 50g added on each rim. Is it your E-bike mid-motor or hub motor? What is your hubs brand and dimension as below? For spoke caculation, it needs hubs specs. Then we can get the spoke length for your reference. - Internal hole rim or external hole rim - Hub manufacturer name and model - Hole count - Front and rear axle width - Straight pull or J-bend? Thanks, Lightbicycle

Manfred 2018/08/19

Hi, I ride the RM650BC05 for about 3 years. It works very well. Because of wheight: It is possible to order especially a light rim (e.g. -15gramm) that is nearer at the weight of RM650BC05? Greetings Manfred


LightBicycle 2018/08/20

Hi Manfred, The AM733 650B rim is wider and deeper than RM650BC05. If we make it similar weight to RM650BC05, it will make the rim much weaker. Thanks, Lightbicycle

Hi Gary, I like to order 27.5 650b Rims laced to hope pro 4 32holes. Front 20mm by 110mm and rear 150 mm by 12mm. Can u pls advise on the wheel spokes length needed and nipple size thanks in advance, panda


LightBicycle 2017/03/09

Hi Panda, Due to the complexity and variations with calculating spoke lengths, we cannot guarantee the spokes will be the perfect length for your wheels. For this reason it is best to confirm the spokes length with your own builder. Below are the spokes length we used for your reference only. -Wheelset: EN733 built with Hope pro4 front 20*110mm/ rear 12*150mm 32H hubs and 14mm nipples -Lacing pattern: 3 cross for front and rear -Front wheel: 259mm-NDS, 261mm-DS -Rear wheel: 260mm-NDS, 260mm-DS Thanks, Lightbicycle

Ryan 2017/01/13

Is the en733 suitable for industry nine 2.9/2.7 butted spokes? Thank you.


LightBicycle 2017/01/14

Hello Ryan, Thanks for your inquiry. The strongest spokes that can be used on our rims are double butted 2/1.8/2mm. The industry nine 2.9/2.7 butted spokes are too stiff to use with carbon rims. It is not allowed to be used on our rims or there is no warranty. Can you change to double butted 2/1.8/2mm spokes? Thanks, Lightbicycle
