WR40 Disc X-Flow Carbon Gravel Rim

Hi Sam, Thanks for reaching out! Yes, the WR40 rims are available with carbon spokes. May I know which hubs you want to build with the wheelset? Then I could make the recommendation accordingly. Best regards, Light Bicycle

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

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

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.

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

LightBicycle 2021/08/06

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
