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.

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.

INFO

TECH

WARRANTY

Our 34mm wide AM728 rims have become our most popular asymmetric product thanks to its versatility. The 28mm inner width offers a wide and stable tire profile for your enduro tires, without becoming square-edged. You can easily get away with running 2.2’s or 2.5’s, but 2.3” - 2.4” tires are the sweet spot. The EN version has an extra wrap of 3k carbon fiber around the nipple bed, and reinforced sidewalls support G-Out forces, and increased rim stiffness, increasing suitability for aggressive riders over 200 pounds.

More air volume, a wider stance, and the bead seat retention system will keep your tires in place on race day and provide an incredibly solid tubeless platform. Wheel stiffness is further increased with a deep profile, allowing for cornering and charging through rough terrain with more speed and confidence than ever before.

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.

I'm trying to use coupon code H8VYJMAC for buying rim EN728 but it says it is invalid

LightBicycle 2018/12/25

Hi Brian, The coupon code is for global warehouse(China) now. If you purchase from North American warehouse, the code can not work. Thanks, Lightbicycle

Dan 2018/12/26

Thanks for sharing this. I missed the coupon by 12 hours so I’ll be buying elsewhere.

LightBicycle 2018/12/26

Hi Dan, I am sorry about that! If you miss the coupon, we can work on invoices with the same discount for you. Do you like to order AM728 rims? How many? Thanks, Lightbicycle

Hi, I am looking for a pair of EN728 32H rims, what is the max psi and spoke tension ? Thanks. Ryan

LightBicycle 2017/06/12

Hi Ryan, The max tire pressure for this rim is 75psi. And the recommended tire pressure is 20psi ~ 30psi, you can have a try. The max spoke tension is 180kgf. Normally, we use below spoke tension for wheels building. Non-drive side: 80 ~ 90kgf, Drive side: 110 ~ 120kgf Thanks, Lightbicycle

Sake 2016/12/15

Hello, I already have a set of Hope pro 4 evo hubs. Do you know what spoke length I will need when buying these rims? Thanks in advance.

LightBicycle 2016/12/17

Hello Sake, 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. If you still like us to calculate the spokes length for your reference, please confirm below details. • Hole count • Front and rear axle width • Straight pull or J-bend? • Spoke nipple length? 14mm? Thanks, Lightbicycle

Sake 2017/01/07

Hi, the hole count is 32 widths are 15x100 and 12x142 the hubs are J-bend spoke nipples are 14mm yes thank you

LightBicycle 2017/01/09

Hello Sake, It will be great if you answer your reply via email. Then I will create the purchase link based on our email record when you are ready to order. Thank you! Thanks, Lightbicycle

I would like to order EN728 32h with dt swiss 240s boost hubs, and dt revolution spokes. Can you please let me know what the spoke lengths would be for drive and non-driveside? Thanks!

Light-Bicycle 2016/11/07

Hello Jaco, Thanks for your inquiry. We can build the wheels directly if you order the rims/ hubs/ spokes here. Does that work for you? The price is much expensive is you buy the parts separately. Thanks, Lightbicycle

Francesco 2016/10/05

Already buyed an EN728 wondering if you coul give me spokes lenght for 32 hole hub kong rear 142x12 by Tune

Light-Bicycle 2016/10/09

Hello Francesco, Sorry for the late reply. We were on National Day vacation during Oct 1st ~ 7th. For spokes length, it will be great if you confirm with your own builder. Because different builders and lacing pattern will use different spokes length. Or please let us know the following and we can calculate the spoke length for your reference. • Hub manufacturer name and model • Hole details as attached picture showed • Straight pull or J-bend? . Lacing pattern? Thanks, Light-bicycle

simon 2016/09/12

hello. could i run tire width of only 2.1 inches on these ID28mm rims? regards Simon

Light-Bicycle 2016/09/13

Hello Simon, Thanks for your inquiry. The recommend tires size for AM728 is 2.1'' -2.7''. So you can run the 2.1'' tires. Thanks, Light-bicycle

Jem 2016/09/08

My body weight is 57kg and I am riding a 160mm travel full suspension bike. Will the 28holes AM728 be strong enough for Enduro use?

Light-Bicycle 2016/09/09

Hello Jem, Thanks for your inquiry. You are not a large rider, so 28H rim is suitable for you. If you ride aggressively, then go with the EN728. The enduro version is a heavier weight due to the additional reinforcement. The thicker walls can handle heavier and more aggressive riders making this the best choice for Enduro style riding. Thanks, Light-bicycle

Ron 2016/09/05

I purchased a EN728 and AM728 hoops to build up. what spoke length do you use for Hope PRO 2 hubs 32H in a 3cross lace pattern? Also can a local purchase be made for what I need? Thanks

Light-Bicycle 2016/09/06

Hello Ron, Thanks for your support. I checked with our builder, and below are the spokes length we use for EN728 and AM728 wheels built with Hope pro2 32H hubs. -Lacing pattern: 3 cross for front & rear -Front wheel: 264mm-NDS and 266mm-DS -Rear wheel: 265mm-NDS and 265mm-DS 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 will be better if you double check the spokes length with your own builder. Because for different builders and lacing pattern, the spokes length will be different. It is best to source the spokes locally, however we can also sell them if they cannot be purchased locally. Thanks, Light-bicycle
