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: 1 Year Warranty, 1 Year Crash Replacement with 15% discount

   Flyweight Rim: 1 Year Warranty, 2 Year 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.

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.

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

Hi, Can I order the 29er flyweight rim without decals?
LightBicycle : (2018-01-04)
Hello Sam, Thanks for your inquiry. It is okay to order the 29er flyweight rim without decals. If you like to place the order through our website, you can leave a massage that “you like rims without decals” when you place the order. Then we will see it and send you the plain rims. When you checkout, there is a message box for leaving message. 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

Does the 100kg weight limit apply to the flyweight as well? I'm about 80kg could I use the flyweight or should I stick with the standard. I will be using these for XC
LightBicycle : (2017-10-01)
Hi Scott, Thanks for your inquiry! The max weight limit for flyweight version is also 100kg, so it’s strong enough for you. Thanks, Lightbicycle

Hi, I'm checking in on the gravel rims you mentioned above. Will there be details released soon? The RM29C06 are nearly perfect for what I'm looking for but the possibility of your new gravel rims being able to run slightly higher PSI (50-60) sounds like it would hit the sweet spot providing they don't have massive weight gains. Thanks!
LightBicycle : (2017-09-19)
Dear John, Thank you for your inquiry! We recommend to use less than 40psi on RM29C06 rims. There will be a risk to have tire blow out problem if it is with higher tire pressure. We also recommend our new gravel 29er RG922 rim with hook as attached. It can hold 120 psi tire pressure. Does it work for you? Thanks, Lightbicycle

Paul : (2017-07-27)
Any chance you could make these with a bead hook? I want these for road use, and 40psi won't be enough for me; If I could run these at 80psi they would be amazing. If they had a bead hook they'd be safe at higher pressures, yes? A set of 280 gram climbing rims would be incredible for road use.
LightBicycle : (2017-07-30)
Hi Paul, Sorry for the late reply. We were out for travel last two days. Actually, for rims with bead lock, it can not hold 80psi either. If you like rims hold 80psi while riding, it is better to go for hook rims. We will have attached new gravel rims 29mm wide/28mm deep coming soon. It can hold more than 100psi while riding. Does it work for you? Thanks, Lightbicycle
Adam : (2017-08-02)
Hi, I'm interested in the new gravel rims 29mm wide / 28mm deep you mentioned. When will they be available and do you have any more information?
LightBicycle : (2017-08-03)
Hi Adam, Thanks for your massage! The new gravel rims(29mm wide/28mm deep) will be available in around 20 days. I will e-mail you the quotation once it can be ordered in time. Is it okay for you? Thanks, Lightbicycle
Tyler : (2017-08-07)
Hi I am also interested in the Gravel rims for CX racing. Please also send me a quote for a pair at 28h drilling when available as well as weight and cost. Thank you!
LightBicycle : (2017-08-08)
Hi Tyler, Thanks for your inquiry! The tire pressure for WM29C06 wheelset should be less than 40 psi. Could you tell me how much tire pressure you will ride? And then we can have a further check whether it is suitable to you. We have another gravel bike rim, it is with hook, can hold high tire pressure. Thanks, Lightbicycle

Hello, I want build wheels with RM29C06 Standard for gravel bike. I don't want to use wider rim like RM29C19 (like in my mtb) but I weight 98kg. Can you increase rider weight limit with additional reinforcement ? Thanks, Yann
LightBicycle : (2017-07-07)
Hi Yann, Thanks for your inquiry! For RM29C06, it is hookless. For gravel riding, the tire pressure is higher than mtb rims. We are afraiding of tire blowing out. We recommend to wait for our new gravel rim as attached picture. It is with hook, to hold higher tire pressure. It will be USD269 each. We can make the rims stronger by adding some more carbon fiber material. What do you think? Thanks, Lightbicycle
Yann : (2017-07-10)
Thanks you for all informations ! I'm sorry, I never look in road section. The RR36C02 is perfect : not expensive, 125kg weight limit, 60psi max for hookless (i ride with 30-35 psi with my gravel actually, 38mm tire on ztr archex). I found my happyness !
LightBicycle : (2017-07-11)
Hi Yann, Yes, the RR36C02 rims are suitable for 30-35 psi gravel riding and can fit 38C tires. It should less than 40psi for hookless version. Please check our quotation as below. RR36C02 rims: clincher, hookless, 28mm wide/36mm deep, UD matte? Front 24H/rear 28H? No brake surface for disc, USD170 each Thanks, Lightbicycle
