Bead type This is a required option.

Hook is for road riders who value aerodynamic gains and mostly ride on smoother roads. If you plan to run high pressure, then a hooked/clincher rim is a safe bet.

Hookless is for those who are running wider tires, lower pressures, or are riding on rougher roads. You will benefit from a more comfortable ride due to the higher volume and increased impact protection. Gravel riders and cyclocross riders are often in this situation.

Both hook and hookless rims are built using the same dimensions and materials.

Finish This is a required option.

Paintless: The "Finish" relates to how the rim is coated or painted such as matte or glossy for the most common applications. Our Recon Pro and Falcon Pro rims feature BlackTek and come out of molds as a completed product, with a scratch resistant and near flawless finish, eliminating the need for coating or painting. We name this kind of superior finish the paintless.

Crystal Painting: A fantastic painting effect designed by Light Bicycle.

Full Custom: This option offers custom finish such as Satin/Raw etc at no extra charge but subject to rim models with 3~5 days LONGER on manufacture. And custom color painting is also available with added 15g/rim and extra $20USD/rim as a start. If you select this option and LEAVE YOUR REQUIREMENT IN QUOTES IN THE NOTES AT CHECKOUT, we will reach out to you once the order is placed to finalize the details.

Weave This is a required option.

The layup schedule is predetermined for each model, but you can choose the outer layer for cosmetic appearence.

The rim strength & weight is virtually identical.

Matte UD is the most popular and has a subtle look.

The futuristic Hexa-Comb and Braided UD are smooth and looks great on deep rims.
More info about Weave >>

Full Custom: This option (if provided here to choose) offers custom weaves such as 3k twill vertical/ horizontal/ Braided UD etc with extra charge of $15USD/rim as a start but subject to rim models with 3~5 days LONGER on manufacture. If you select this option and LEAVE YOUR TAILORED REQUIREMENT IN THE NOTES AT CHECKOUT, we will reach out to you once the order is placed.

Braided UD USD +15

Rim Warranty This is a required option.

For Recon Pro Series ( MTB rim), Falcon Pro (road rim) and Drift Pro (fatbike rim), 5-year warranty is set as standard, and optional Lifetime Premium Warranty are kindly offered to purchase with minimum charge respectively.

5 Years

Lifetime USD +100/rim

Center Channel Hole This is a required option.

With Access Holes: This is the traditional method. Spoke access holes are drilled in the center channel to allow the nipples to easily be fed through the rim. Tubeless tape is required to seal the rim.

No Access Holes: No spoke access holes are drilled in the center channel. Feeding the nipples through the rim is more challenging, but it allows for a tubeless setup without the need for tape. This kind of system is known as "road tubeless" and was made popular by Mavic. Some companies still refer to it as "UST style", however, UST is actually a specific interface between the tire and rim which was developed by a partnership between Mavic, Michelin, and Hutchinson.

Currently, rims with 'No Access Holes' do not work with our carbon spokes.

With Access Holes

No Access Holes

Drain Hole This is a required option.

The two small drain holes located 90° to the valve hole effectively help evacuate both the water trapped inside the rim and the air leaking into the rim chamber caused by nonperfect tubeless tape sealing handwork that may risk rim explosure in an aggressive tire inflating.

It is the small reinforced layer prelaminated on the area where the drain hole is drilled later that makes the rim strength fairly ensured without any compromise of weight added.

Riders who ride in wet areas are suggested to order rims with drain holes.

Decal This is a required option.

1. Grey Laser Engraving (Falcon Pro) - Our laser engraving technology is eco-friendly and adds a snappy, polished aesthetic to your new rims.
Please note: Contrary to rims with any coated/painted finishes (matte, glossy and satin) as well as Crystal Painting, laser engraving could work with paintless rims only.

2. Full Custom - Add some additional personalization and go full custom with your rim graphics! Laser engraving is available in one colour (light grey) and starts at $5 USD per rim. If you select this option, LEAVE YOUR REQUEST IN QUOTES IN THE NOTES AT CHECKOUT. For example: "I need my personalized logo printed" or "Just text 'ABC racing' ". We will reach out to you once the order is placed to finalize the details of custom graphics.

Valve Stem This is a required option.

We use a lightweight black alloy anodized valves 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 valve core is removable so you can add sealant without removing your tire.

light-bicycle-wr40-disc-brake--best-wide-road-carbon-wheels-installed-on-a-specialized-bike

Adam : I really like the WR40 rims, they feel fast and stiff while also giving you a lot more confidence when hit with strong cross winds. You can really feel the waves working to your advantage and keeping the wheels where you want them to go. The wider inner width is also very nice; it gives the tires a really wide contact patch, which feels extra grippy in corners. I ordered mine with internal nipples and Sapim CX-Ray spokes; the wheels feel super fast and still very comfortable. Light bike built my wheels for me and did an exceptional job on the lacing/tensioning. I couldn’t be more satisfied. They even managed to push my wheels ahead of production, so I'd have them by the time I'm on vacation. 10/10 will order again from light bicycle wheels. More builds on the way. :)

light-bicycle-wr40-disc-on-a-pivot-vault

Tom : I wanted to upgrade my Pivot Vault with a really nice set of gravel wheels for ultra races and just having fun. When I saw a picture of a pair of crystal green painted rims I fell in love and despite my bike not having any green on it whatsoever, I just had to have them! So I ordered a pair of wavy WR40 rims (hooked with no spoke holes) built onto DT240 hubs with CX-Ray spokes and red alloy nipples. I also ordered a 3rd rim so I could get my existing SON 18 dynamo hub built up at home. Now I've been using the wheels for over 6 months now in all kinds of conditions and they're amazing! Having no spoke holes means no rim tape needed and this is a game changer for tubeless, I've barely had to pump up the tyres since I first set them up!

maxime 2024/10/26

Hello, I'm french, bad english speaker so chat-gpt , helps me with this: I have a Shutter Precision PL7 dynamo hub with 28 holes in my garage, and I’m considering mounting it on one of your WR40 rims. I have a few questions about this: - I’m a fan of unperforated rims (for better tubeless sealing without tape). How is the spoke nipple installation done manually in this case? Are specific tools required? - I am also considering your Turbo 40D rim. My intended use is long-distance riding (road and gravel), and I weigh 85 kg without the bike (9 kg titanium). What would you recommend? If you think the Turbo 40D is better suited, could you provide it with 28 holes? Would this compromise the rim’s durability? - I plan to use CX-Ray spokes in a three-cross pattern. Could you tell me the appropriate spoke lengths and the type of nipples to choose?

LightBicycle 2024/10/28

Hi Maxime, Hi Maxime, Thanks for reaching out. - We usually assemble the wheels 700C without access holes by magnets and our own homemade tools (the threaded part of the spoke and the nipple combination). Please refer to the attachment. - The WR40 is suitable for long rides and can also do 28 holes. I suggest you ride the standard version. The Turbo 40 is not available in 28 holes. - Could you please provide the hub size? I'll calculate the spoke length for you. Thanks, Lightbicycle

Hello! Coud you please explain the benefits and applications of each of the different weave patterns? Weave: UD, 3K, 3K Twill (Vertical/Horizontal), 12K, 12K Twill (Vertical/Horizontal), Braided UD, Hexa-Comb Also could you please do the same for the different weight styles? Weight Style: Standard, Flyweight, Ultra-Light, Heavy Duty, HD+ I have a friend who weighs less than 150 pounds or ~68kg and cracked a pair of flyweight rims. I weigh 175 pounds or ~80kg and am concerned about the durability and reliability of these rims. What would you recommend for a gravel specific application?

LightBicycle 2023/04/06

Hi Eli, Thanks for reaching out! Weave options are mostly cosmetic options. The internal fibers are all UD fibers because they are the strongest fiber among them. I would recommend UD fibers as they look very neat and slightly lighter and stronger. About weight customization options. our recommendation for flyweight rims normally lies in the 90kg (on flat) limit. But riding conditions and style should also be accounted for. Assuming you are talking about WR40 rims. If you ride on rough gravel, flyweight rims are only recommended for the front wheel. Also, what's the tire and tire pressure your friend uses? What was the scenario when the crack occurred? So, if you are considering building a gravel wheelset. Can you share more about your riding style, conditions, and tire setup? Thanks, Lightbicycle

Paulin 2023/03/31

Hello, i am currently considering buying a pair of Falcon pro WR40 rims. Assuming I go with the hooked version, without access hole, would I need to tape the rims in order to have tubeless road tires to seat properly, or can I use them without tape? I am considering using them with Michelin Power Cup in 700x30 mm, tubeless, if that matters.

LightBicycle 2023/03/31

Hi Paulin, If you order WR40 rims without access holes on rim bed, you will not need to use rim tape any more.It is okay to use 30mm tubeless tires on WR40 pro rims 700C disc. Please let me know if you have any other questions. Thanks, Lightbicycle

Simon 2023/02/23

Hi, I have a pair of WR40 (hookless, paintless, UD, laser engraved logo) custom built with 28L / DT 240 / Aerolite from my local wheel builder. The wheels look great, very stiff, perfect for tubeless gravel riding.m Highly recommended! Recently another cyclist ran into me, his front tire was rubbing on my fancy rims :(. The rim is undamaged, wheel barely out of true. There are some strips where the surface is now matte instead of glossy. It’s a purely cosmetic issue, the marks can be seen depending on the viewing angle, but cannot be felt with the fingertip. Do you have some advice how to polish the rim to restore the glossy look? PS: The surface/finish your rim is very sturdy, given the tire grinding with road dirt in between not even causing a groove.

LightBicycle 2023/02/24

Hi Simon, I am glad that you are ok. Can you take a photo of the searches so I have a better idea about it? Thanks, Lightbicycle

Hi, if necessary can an inner tube be used on a hookless rim after a puncture that doesn't seal? Just trying to decide between hookless & hooked. Thanks!

LightBicycle 2022/03/10

Hi Donald, If you ride tires with tube, it is better to choose hook version. How much tire pressure will you ride on this WR40 disc rims 700C? Thanks, Lightbicycle

Hello, what tool do you use to get nipples inside of the rim without drilling from inside? Do you maybe have a video how to do it? I have WR40 disc here. Thank you Richard

Hi Richard, Yes, we have a video for UST-style wheel WR40 road disc building. You can find the QR code of the video in the "user manual" since you already have the rim. Or you can see details from this article. https://www.lightbicycle.com/newsletter/TUBELESS-READY-OR-TUBELESS-RIMS--WHAT-S-BEST-FOR-ME.html Thanks, Lightbicycle
