For new 29er rim is bead hook-less, it is light & stiff. It is specially designed for customers who likes to build light weight wheelset & bike.


The Flyweight is a new series of rims from Light Bicycle. Targeted specifically towards racers who seek every possible edge on the race course. Our goal was the produce the lightest possible rim without sacrificing performance. Through revisions in each step of the manufacturing process, we were able to produce a strong, light and competitive rim.


* For unique hole drilling and alternate options, please contact us for special orders.

* New Flyweight matte clear coating process. Not available with glossy finish.

* Standard Rim: 15 Months Warranty, 15 Months Crash Replacement with 15% discount

   Flyweight Rim: 15 Months Warranty, 30 Months Crash Replacement with 25% discount

* If you would like a coloured graphic, we can apply a sticker over top of the rims, this will add about 5g per 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.

  • Lightweight
    Standard: It is the light one around our current 29er rims, the good choice for lightweight 29er wheels & bike.
    Flyweight: It is a new series of rims from Light Bicycle. Targeted specifically towards racers who seek every possible edge on the race course. 280 grams only!
  • Precise layup
    Standard: 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.
    Flyweight: New layup design at the nipple bed to reduce the amount of material required and reinforce the key area around the spoke holes.
  • 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.
  • Tubeless
    While the rims are optimized for a tubeless setup with the addition of tubeless tape, they also work with tubes.
  • 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.
  • Material
    Standard: Constructed with premium Toray T700 carbon fiber. The good strength to weight ratio with no expense spared.
    Flyweight: Hybrid construction of Toray T800 and T700 was used to reduce wall thickness in key areas while enhancing the overall rim stiffness. These rims are available with the UD material only due to the strict standards required to produce the Flyweight model. We used a lower FAW (fiber areal weight) and a thinner prepreg to achieve a more adjustable layup schedule design which reduces the stress between the layers of carbon fiber.

Greg Zagar : I'm very excited for this build. The more people that can enjoy it, the better! I still have a lot of incoming parts, and work to assemble. But in the north east United States, it's time for skis! I have nothing but time and excitement for this bicycle project. You are more than welcome to share pictures of the complete project that I will send once finished.
Dave Speed Dream Wheels : Hi,Just want to send some pics of your rims on my bike!!I love them!!Dave

Andreas Schaad : Thank you Light-Bicycle team! Two beauties are born!! The superlight Flyweight disc rims with Novatec alu/carbon hubs and straightpull sapim cx ray's. At 1196g for front and rear they perform absolutely superb on my cyclocrossbike!!

William Blaney : I bought light bicycle wheels for it last year and they're great. Here's a picture from last fall in Crowsnest Pass on top of a mountain there...
Erik Olsson : These are the best wheels I have ever ridden. After almost 3000 miles on my rims they are still perfectly true and strong. I recently hat the rear rim re-laced to a boost 148mm hub to fit my 2016 Orbea Occam TR 29 carbon and it is still perfect. I have had numerous friends on ENVE rims have multiple problems but I have yet to experience any of my own. They are a better price and better quality than everything else I have ridden so far.

Steven Descheemaeker : i received the rims on friday from Karel who is back in belgium. First impression : they look great :)

Hi There, Are these available with no decal? Thanks!
LightBicycle : (2018-07-10)
Hi Luke, Yes, you can order plain rims only (without the decals). Do you want the standard version or the flyweight version? If you do not choose on decal color, the bike rims will be shipped without any graphic. Don't worry. Thanks, Lightbicycle

Ciao, I recently crashed my CZero carbon rims on my Scalpel Carbon. I'm considering to buy a pair of 29C06 Flyweight rims (to be re-build on existing hubs) . My weight approx 76-78 kg. Level of riding: XCO training/racing in all type of conditions. Does the 29C06 meet the requirements?
LightBicycle : (2018-07-05)
Hi Chris, Few questions for you before you place the order. Let me learn more about your riding condition to make the proper recommendation. 1. What is the tire width you use? The recommended tire width for RM29C06 is 2.0~2.2". 2. Are you an aggressive rider? You are not a big guy, so as long as you don't ride aggressively, The flyweight is ok. 3. Do you ride rocky terrain often? Then we can check whether flyweight version 29er mtb bike rim is strong enough for you. Thanks, Lightbicycle

Hello What are the spoke tensions for the 29C06 flyweight rims with dt swiss 240s straightpull hubs and with the dt swiss competion race spokes. Thanks
LightBicycle : (2018-07-04)
Hi Aaron, We use the following spoke tension range while building symmetrical MTB wheels, pls take it as reference Front hub: non-drive side 115~125kgf, Drive side 85~95kgf Rear hub: non-drive side 85~95kgf, Drive side 115~125kgf It’s better to make sure that the max spoke tension under 135kgf. Thanks, Lightbicycle

Hello ! The specified weight limit that includes? My weight is 90 kg. Consider buying a lightweight rim. For my weight, they fit? Or should I choose the standard version?
LightBicycle : (2018-04-28)
Hi sir, RM29C06 flyweight version is for light XC riding. Could you kindly tell me what kind of riding you do? Are you an aggressive rider? I need more info to tell whether the flyweight version is right for you. Thanks, Lightbicycle

Why is the RM2906 only rated at 40PSI? The hookless rims from several other manufacturers can run higher pressure and theirs is hookless. I only need 10more PSI. I would like to run these at 50 PSI with a 28mm tire for both some gravel roads and some tarmac. I only weigh 72.5kg. I would love to use your RM2906 because it is so light but the PSI is making me think about it. I see your gravel rim but would rather use this rim if I can.
LightBicycle : (2018-02-13)
Hi Roger, 40psi is the tire pressure we recommend to you that keep tire safely on the rim and make sure your rims at their best performance during riding. Normally, nobody would ride over 40psi during riding. 70psi is the tire pressure we used on lab when testing the rim mounted with an inflated tire. 70psi is the max tire pressure. We highly NOT recommend run with high pressure. Thanks, Lightbicycle

I am right on the edge of the weight limit for the flyweight. I know the tires are rated for "XC", but what testing methods are being used to determine weight limit. Would the flyweights hold up to "trail" riding at their max rated capacity?
LightBicycle : (2018-02-07)
Hi sir, What kind of riding style will you ride on RM29C06 rims? Do you ride aggressively? Normally, RM29C06 flyweight is for racing only. While normal training, it is better to use standard version for daily training. Thanks, Lightbicycle

Can you make a hooked version of the RM29C06 Flyweight capable of higher psi? Would make an excellent light rim for fatter road tires.
LightBicycle : (2017-10-14)
Hi Kevin, Thanks for you inquiry! Currently, we do not have this rim in hook version. Do you ride road or road disc? May I know your tire width and your weight please? What about your usually tire pressure? Then we can check which is the suitable and lightest rim for you. We have RG922 hook(29mm outer/22mm inner). It should be okay for you. Thanks, Lightbicycle

Rob : (2017-10-02)
What is the recommended smallest tyre to use on these rims? Would they be suitable for cyclocross? I am also interested in the new gravel rims (RG922), are they available yet? Thanks.
LightBicycle : (2017-10-08)
Hi Rob, Sorry for the late reply. We were on National Day vacation from October 1st to 7th. We are just back to work today. How much tire pressure will you use? Then we can check whether RM29C06 rim is okay or not for your cyclocross riding. It is hookless design, it is better to make sure the tire pressure is less than 40 psi while riding, to preventing from tire blowing out while riding. Please check our RG922 gravel rim profile as attached. It is 29mm wide and 28mm deep, with hook design. It can hold tire pressure that is higher than 100psi. Thanks, Lightbicycle
