INFO

TECH

WARRANTY

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 to produce the lightest possible rim without sacrificing performance.

Drawing on our engineers’ years of experience and countless revisions in each step of the manufacturing process, we are able to produce a strong and stiff XC rim while dramatically reducing the weight.

Construction: We used a special uni-directional pre-preg with a very low fiber areal weight. This is an exclusive process to our Flyweight rims. To further reduce the weight we used a blend of Toray T700 and T800 specific layups. We opted for a new subtle ultralight waterslide graphic in glossy black with a matte finish overtop in the spirit of keeping these as true cross country race oriented rims.

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.

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

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.

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.

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.

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.

Michael : Hello Grace! The time has come - the cyclocross season is in the starting blocks! And finally I can race my wheels, which I built in May With "Flyweight" carbon rim from Light Bicycle, Newmen hubs and SAPIM CX-Ray spokes, I've built a super lightweight wheelset of 1124g! It was really fun, the rims are very fine and precisely made, in the end I was almost sad when the wheels were finished, since building was so much fun! :-) But with the wheels on the Crosser, the fun really goes on: The Crosser can accelerate really cool with these wheels; It is noticeably better to accelerate out of the curves and even in the terrain it's really like flying over the trails.” Thanks an Best Regards

Germany

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.

USA

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!!

Switzerland

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.

Dave Speed Dream Wheels : Hi,Just want to send some pics of your rims on my bike!!I love them!!Dave

Jakob 2019/09/19

Hello, in 2017 I purchased a set of disc mtb wheels, WM29C06. I have since sold the bike, but still have the wheels. I would like to convert them for a CX bike with rim brakes. Are the rims capable of working? I am thinking the brake surface is the only thing in question. I am only 75KG and they will be used as pit wheels. Thank you, Jakob

LightBicycle 2019/09/20

Hi Jakob, So good to know that your WR29C06 still works well since 2017. The rim brake surface special material and resin system supposes to put on the rim before molding. You can not use a disc rims on a rim brake now. There is not special brake surface on these mtb bike wheels. So my suggestion is, buy a new set of wheels that made with rim brake. It would also take a lot of effort to convert a rim brake bike to a disc brake bike as well. So buying a new set would be the best option. Thanks, Lightbicycle

Tom 2019/06/23

Hi, how much are the 27mm 29er recon rims in flyweight version? I need a pair with 32h drilling for gravel/CX/fat road tyres. Highest psi I run is around 55psi. How much for 2 rims posted to the UK? What spoke tensions are recommended for these flyweight rims? Thanks, Tom.

LightBicycle 2019/06/27

Hi Tom, The flyweight version of 29er XC rim RM29C06 (27mm wide) is USD158 (UD, matte, 32H) each. For the flyweight version, our recommendation usage would be for the front wheel of a CX bike (or gravel bike). I would also have to point out that the rider weight limit of this particular rim is 90kg. If you are heavier than 90kg or riding a bit aggressive, the rim won't be a good choice. Normally, we recommend using the flyweight version for the front wheel and the standard version for the rear wheel. Riding with 55psi is totally ok for rim RM29C06 as our recommendation tire pressure is under 60psi. Max spoke tension is 135KGF. Please do not exceed 135kgf while wheel building. We also email you the spoke tension chat we normal use for your reference. Thanks, Lightbicycle

Tchell 2019/04/15

I am looking at the flyweight version of the RM29C06. I am 81Kg (180 lbs). I am a 60yo I ride mostly single track mountain trails in Utah. I am a strong rider on smooth single track. I do not do any rough rocky terrain , no drops, air etc. Could I go with the flyweight or standard?

LightBicycle 2019/04/16

Hi Tchell, Since you are not doing aggressive riding and not a heavy rider yourself, we recommend using the flyweight version on the front and the standard version on the back. Are you looking for building a complete 29er XC wheelset from us? or carbon fiber bike rims only? Thanks, Lightbicycle

Henrik 2018/08/19

Hi Are you planning to launch the flyweight version with a wider internal mesurement like e.g. 25 mm?? And will it be possible to order a wheelset with 24 spokes in front and 28 in rear ?? Kind regards Henrik

LightBicycle 2018/08/20

Hi Henrik, Yes, we are planning on launching a new MTB series that with few flyweight version rims. The estimated launch time would be around September. Thanks, Lightbicycle

Chris 2018/07/04

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 ! 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

Roger 2018/02/12

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

Fkent 2018/02/06

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
