Sapim Race – Our strongest and stiffest spoke. These spokes are suitable for heavy or extremely aggressive riders who need a stiffer wheel.
Sapim CX-Ray – The lightest spoke in our lineup is still quite strong due to the elasticity and amazing fatigue life.

DT Competition Race - All Mountain and XC spoke used by the Chinese location as a substitue for the D-Light (depending on availability)

Pillar PSR X-TRA 1420 - An inexpensive bladed spoke, great for road and cyclocross riding.

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 rim page.

As more bikes become compatible with massive 2.8-3.2” tires, AM740’s are the opportunity to upgrade your ride into a plus bike, while still experiencing the incredible traction and stiffness only a lightweight carbon wheelset provides.


Not only are carbon plus wheels dramatically lighter than alloy, they are stronger as well. Running your alloy rims at low pressure usually means plenty of dents and a sluggish ride. Fortunately, AM740 solves both these problems with an incredibly durable and stiff profile, unleashing a new level of performance from your plus bike.

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, 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.

Hi, I am interested in the following wheelset built on AM740 rims REINFORCED, as I ride an ebike (2.8 tires) in very rocky terrain (my weight is 85kg, ebike 23kg): Front axle:15 / 110mm BOOST Rear axle: 12 / 148mm BOOST Freehub body:Shimano MTB 10/11S Brake system:6-bolt Front holes:28H Rear holes:28H Hub Color:Black Hub :Hope Pro 4 Finish:matte Weave:UD Also, could you please give me a price for TPD delivery? Thank you, L.


LightBicycle 2018/11/23

Hi Lorenzo, Yes, we can make a stronger version for you considering your riding condition. With extra carbon fiber, the estimated weight of the rims would be 630±25g. Is it ok with you? 28H would be a little risky to ride on rocky terrain, especially with an e-bike. I would recommend you go with 32H spoke count. For E-bike wheelset, it is better to choose DT competition 2.0/1.8/2.0 spokes or sapim race 2.0/1.8/2.0 spokes. Thanks, Lightbicycle

I’m looking at a pivot switchblade that has one 57 x 12 rear hub spacing can you build that?


LightBicycle 2018/08/29

Hi Bill, Do you mean 12*157mm DH or 12*157mm super boost? We have both of them. Please check which you like. Then we can quote accordingly for you. Do you like rear 650B wheel only or front+rear wheels? Thanks, Lightbicycle

Kirk 2018/05/31

Hello. I am a 200lb rider. I am wondering if I should get the AM740 or the EN740. I am not an extremely aggressive rider on a full suspension 130mm travel bike.


LightBicycle 2018/05/31

Hi Kirk, Basing on your weight, my suggestion is to go with the enduro version (EN740), 650B enduro rim. The additional carbon fiber makes the rims stronger and stiffer. Thanks, Lightbicycle

Hi Peter, Yes, we can make a wheelset for your Cannondale AI frame with 6mm offset. We actually build quite some wheels with AI 6mm offset for our customer in the past. Which fork do you use? What we built for our customers are like the attachment suggests. Thanks, Lightbicycle

Hello David, Thanks for your inquiry. We can build the AM740 wheelset with DT 350 boost hubs and Sapim cx-ray spokes. May I know what your electric bike weight is? What is your weight? Then we will check if we need to add some carbon fiber to enhance the rims’ strength. Thanks, Lightbicycle

Stephen 2017/05/07

Hello guy's just looking for recommendation really, thinking of going carbon rims on my enduro bike, I do a lot of uplift days & aggressive trail rides at home (peak district in Derbyshire, UK) I'm looking at 40mm AM wheel sets are they up to the job? I'm 6ft & about 175lbs & ride at least 3 times a week with some all day rides too! Oh & lead time to the UK for delivery too! many thanks Steve.


LightBicycle 2017/05/08

Hello Stephen, Thanks for your inquiry. The AM740 is design for plus bike but suitable for aggressive mountain bike riding also. May I know what the tire width you use normally? Then we will double check if the AM740 is the best choice. Because I think our AM733 is more suitable for your riding. Thanks, Lightbicycle
