3k/12k/UD are the 3 choices for cosmetic appearance.The rim strength & weight is virtually identical.
UD Matte is the most popular and has a subtle look.

UD

Center Channel Hole This is a required option.

WITH HOLES: This is the traditional method. 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.


WITHOUT HOLES: No 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.

Without Holes

Decal This is a required option.

Road rims use super light waterslide decals (glossy black). The decal is very thin and applied under a clearcoat so they are non-removeable.

Valve Stem This is a required option.

We include enough valves to cover your individual rim purchase. 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.

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.

The RG922 is one of the newest members of the Flyweight family and part of our Falcon road line. With an asymmetric profile and 22mm internal width, this rim is designed for high performance ultralight wheelset builds.


Our Flyweight construction method uses a blend of Toray T700 and T800, and a thinner pre-preg for a lighter rim weight without reducing the actual number of layers in the layup schedule. Our spoke hole patching treatment removes unnecessary weight from the nipple bed, making this rim a truly light, high pressure-capable product with a weight of just 380g.

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


Wider: The wide profile offers improved aerodynamics, better handling in crosswinds condition and faster riding.


U-shape: The aerodynamic shape makes road tubeless rims lightweight but still stiff, keeping them stable in cross winds.The advantages of the U-shaped Road bike rim 700C


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.


Tubeless ready: beadlock design making this light weight road rims better tubeless setup and better sealing.


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.


Asymmetrical: The profile allows for equalized spoke tension which creates a stronger wheel that stays true.


Flyweight layup: It is with Hybrid construction of Toray T-800 and T-700 lightweight gravel layup for weight saving.


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.

Henry 2019/02/11

Hello. I'm am interested in the RG922 29er Rim in 32H. I weigh exactly 275 pounds (125 kilos). Is there another rim you recommend, or is this one OK? Do you offer the RG922 32H in a version for a heavier rider/bike? Thank you!


LightBicycle 2019/02/14

Hi Henry, What kind of riding you usually do? What tire width you plan to use? Normally, road riding won't be too aggressive, so your weight is ok for RG922 gravel rim. With 32 spokes, the wheelset you built would be very strong for big rider. Thanks, Lightbicycle

Is there a hookless option for this rim?


LightBicycle 2018/11/29

Hi Rod, The gravel rim you are looking at RG922 (29mm wide, 28mm deep) only provide the hook version for now. If you are looking for a close profile rim, you can look at our RM29C06 (27mm wide, 24mm deep) or the newly launched scratch proof rim XC925 (30mm wide, 23mm deep). You can check out the rim profiles from the attachment. Details are as follows pages. Let me know if you have any questions or want quotes for a wheelset.

Joshua 2018/01/26

Hello, I am looking for the lightest possible rim for my gravel bike. I will use 32~45 mm tyres. What are the reccomented max pressures for this rim? The RM29C06 Flyweight is much lighter could I use it instead? Will it be better?


LightBicycle 2018/01/27

Hi Joshua, Here are the differences between RG922 and RM29C06 flyweight version. 1. Recommended tire pressure: RG922 is 110psi, RM29C06 flyweight is 60psi. If you run over 60psi, we suggest you choose RG922. 2. Max rider weight: RG922 is 125kg, RM29C06 flyweight is 90kg. 3. Weight: RG922 is 380g+/-15g, RM29C06 flyweight is 280g+/-15g 4. Structure: RG922 is with the asymmetrical design, RM29C06 is with symmetrical design. Asymmetrical rim profile, it provides better spoke tension balance between drive-side and non-drive side. It will make wheels more durable. If you ride more than 40~60psi, it is better to go for RG922 rims. Thanks, Lightbicycle
