None

Add Tubeless Tape USD +6

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.

MTB carbon rim profile

Teleport to the rim page.

The Flyweight is a new series of wheels from Light Bicycle. Targeted specifically towards racers who seek every possible edge on the race course. Our goal was to produce the lightest possible wheels 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 wheel 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


Hand-Built: Each wheelset is painstakingly built by hand to tension within 5% variance. Each spoke's tension rating is recorded in our system, as is the roundness and lateral tolerance.


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, 15 Months Warranty
For Pro Series Rims: From the date of purchase, 3 Years Warranty. Light Bicycle is pleased to offer the options to purchase an extended 5-year Premium warranty or lifetime Premium warranty with minimum charge respectively.

Crash Replacement: It is applicable with the same period as to warranty time range that you purchased for the rim in terms of 15-month/ 3-year/ 5-year/ Lifetime, with 10%+ discount subject to rim model.

Patrick 2018/04/10

Any chance you will be making a flyweight XC rim that has a inner diameter of 25 with a outer of 30 or so? This seems to be where DT Swiss and Enve are going with there light race wheels. if you made this I would order it tomorrow! Patrick


LightBicycle 2018/04/10

Hi Patrick, We have RM29C19 with 24mm inner/30mm outer width, will this work for you? https://www.lightbicycle.com/U-shape-29er-rim-30mm-wide-hookless-MTB-bike-carbon-rims-tubeless-compatible.html Thanks, Lightbicycle

When you refer to maximum weight for the standard and flyweight versions, are you considering the combined weight of rider and bike or only rider?


LightBicycle 2018/03/08

Hi Esteban, The max weight is referred to the rider. Note that RM29C06 is intended design for XC racing . May i know your weight and riding style please? Then we can check whether it is strong enough for your riding or not. Thanks, Lightbicycle

Fritz 2018/10/13

Same question I am 175 Ride trails that are sometimes rough Thinking flyweight with 32 hole rims What do you think?


LightBicycle 2018/10/15

Hi Fritz, For the max weight limit, it's 100kg on standard rim and 90kg on flyweight rim. So, the flyweight wheels is OK for your weight and riding. The 32H wheels will be slightly stronger than 28H. The 32H wheels is also 40g roughly added compared to 28H wheels. Thanks, Lightbicycle

will the XX1 freehub accept the XO 12 speed cassette ?


LightBicycle 2017/07/14

Hi Bobo, All Sram 9 or 10 speed cassettes are with Shimano freehub style. Only the Sram 11/12 speed cassettes use the Sram XD freehub driver. Sram has X01, XX1, X1 which all use the Sram XD freehub body. Do you mean Sram 12 speed cassettes? If yes, Sramxx1 is compatible with Sram 12 speed cassettes. Thanks, Lightbicycle

William 2017/03/29

Hi, I have a 2014 Cannondale team scalpel carbon with Enve XC 29er carbon rims. I shattered the rear rim and need a replacement rim. I am looking for the hoop only. I am looking at your 29c06 rim. Is this the closest rim you have to my current Enve? I only need the hoop to repair my wheel. Do you sell just the hoop and what is the cost?


LightBicycle 2017/03/30

Hello William, Thanks for your inquiry. Our RM29C06 rim is designed for XC riding and will work with your bike. It is okay to buy the rim only. Normally, you need to get some new spokes also, because the rim ERD is different, so the spoke length will be different. RM29C07 (27mm width): 360 /-15g, $165/pcs Thanks, Lightbicycle

Hello Ed, Thanks for your inquiry. Hope and DT Swiss hubs are available. But there are not all axle or QR options on our website. Sorry for the inconvenience. Please find our quotations as below. All pricing in USD. -WM29C06 (with Hope pro4 hubs, Sapim cx-ray spokes): $867/pair -WM29C06 (with DT 350 hubs, Sapim cx-ray spokes): $767/pair Thanks, Lightbicycle

Hi Light Bicycle Staff, I have a question- I was looking at your 29er XC 27mm wheelset for use on my cyclocross bike and using 33-38mm cyclocross tubeless tires. Would this work? Best, B5000 葉伯榮


Light-Bicycle 2016/09/01

Hello Mr. Ye, Thanks for your inquiry. The recommend tires width for RM29C06 rim are 1.9’’-2.3’’. The 22mm internal width mountain bike rim is a bit wide for those tires. I am more concerned about the higher pressure when using road tires as the 22/27mm rims are hookless and made for lower pressures (up to 40psi riding pressure). I would go with the 25mm deep or 35mm deep u-shaped road rims tubeless compatible. The internal width is about 18mm which would work well with 33C-38C tires or narrower tires. The clincher bead will handle the pressure better. Some customers prefer the 35mm deep for the back wheel and 25mm deep in the front wheel for weight savings. Also, we are able to manufacture the road rims without brake tracks for disc bike. Does that work for you? Thanks, Light-bicycle

mike 2016/08/31

Have you had any issues with burping or the tire falling off the rim with the hookless setup? specifically with tires that are tubeless ready? Thanks


Light-Bicycle 2016/09/01

Hello Mike, There is zero issues of holding tires for hook-less rims. The rim is without bead hook, it is ok to hold tubeless and tubeless-ready tires. The rim wall is more smooth and straight, and the tire will touch rim walls fully and mounted perfectly. We have sold lots of hookless rims to customers. I am sure that you will like it. Rim profile attached for reference. Thanks, Light-bicycle
