  • 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 here
  • 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.
  • 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.
  • Bead lock
    The small ridges on either side of the drop channel help secure tubeless tires in place. The bead lock makes it easier to seal up tubeless tires with a floor pump, and they are incredibly hard to burp.
  • 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.
  • T700
    Constructed with premium Toray T700 carbon fiber. The best strength to weight ratio with no expense spared.

Bernard Tan : Just to let you know the 29er carbon rims are awesome! I must say they are nicely craft unlike some carbon rim that I have from China. I have already built up & rode with it, very firm on sharp turn. Here is the picture of my bike & light bicycle rims.

Jonas Silver : The green Evil bike is my current ride and go out as often as I can thrashing up the landscape. I truly enjoy your rims and glad to see that you have made a US presence, my only comment to that is that I like Industry Nine hubs, but would have loved to see you partner with Onyx Racing Products as well. These are the hubs I amcurrently running and they are flawless.Again, keep up the great work and I will keep telling everyone that they need to look at you for wheels and rims.

Rikard H : I bought a pair of 38mm 29er rims and are really impressed with the look and quality. My lbs who build them were also impressed with the quality and the end result is spot on. I have never ridden a bike with carbon wheels before so I have no references, though. My first impression is that they are very responsive and stiff, at first I thought I had to turn down the air pressure in my Pike a little. It
Dean : Bike is much better with carbon!

Can you drill these rims to have 27 holes?
LightBicycle : (2016-12-05)
Hello Evan, Thanks for your inquiry. Yes, we can manufacture the rims in 27H. Are both front and rear in 27H? Also, is it 27H spoke holes laced on rim evenly? If not, please help to show us some pictures of the spoke hole drilling pattern. Then we can manufacture accordingly. Thanks, Lightbicycle

Hi. would like to purchase this. got a hub from my specialized stumpy 2014...would u be able to build the wheels for me if i send the hubs? i can send pics of my wheels if that helps
LightBicycle : (2016-11-30)
Hello Raymond, Thank you for your inquiry! For WM29C14, we have UD, matte, 32H rims in stock. The wheelset can be shipped around 3 days later after you place the order. The delivery takes another 7~10days. Does it work for you? Thanks, Lightbicycle

i wpuld like yo purchase a pair of these wheels, I have a set of 23 spoke hubs I would like to lace theae too...is it poasible for me to mail these to you to lace them with your spokes and nipples and then mail them back to me, what cost am I looking at for the wheel build on my supplied hubs thank you i would like red nipples and bladed spokes
Light-Bicycle : (2016-10-19)
Hello Marc, Thanks for your inquiry. It’s ok to send us hubs and build the wheelset for you. We can offer our address once you are ready to ship hubs to us. For bladed spokes, does sapim cx-ray work for you? Thanks, Light-bicycle

what spoke length would i need for dt swiss 240s 32 hole 3 cross
Light-Bicycle : (2016-10-08)
Hello Neils, Thanks for your inquiry. Do you like to order the rims only and confirm the spokes length to build the wheels by yourself? If so, please let us know the following and we can calculate the spoke length for you. • Hub Hole count • Front and rear axle width • Straight pull or J-bend? 6-Bolt or center lock version? • If you are using nipples with larger heads (double square, Squorx, or hex head for example), then we need to know this as the spokes are 1-2mm longer. Due to the complexity and variations with calculating spoke lengths, we cannot guarantee the spokes will be the perfect length for your wheels. For this reason it is best to source the spokes locally, however we can also sell them if they cannot be purchased locally. Thanks, Light-bicycle

How accurate is the ERD for the RM29C14? I will building these to either SRAM 12x148 Boost MTH746 and MTH716 hubs OR to the Hope Pro 4 MTB Rear Hub Boost 148mm x 12mm hubs. Can you recommend spoke lengths for either of these builds so I can get them ordered while waiting on my rims? Do you recommend any particular nipples? Washers needed? Do you have a build guide/ recommended practices for your rims? Thanks!
Light-Bicycle : (2016-07-26)
Hello Mic, Thanks for your inquiry. The RM29C14 rim ERD is 574mm (not including nipple head dimension). We haven’t built the wheels with Sram hubs. Would you please let us know the hubs’ details as attached picture showed? Then we will check the spokes length accordingly. For rear wheel built with Hope pro4 32H boost hubs, we will use below spokes length. -Lacing pattern: 3 cross -Length: Non-drive side 279mm/ drive side 278mm Normally, we use 14mm nipples. And brass nipple is what we recommend. You can have a try. All our wheels are built without washers. The spoke hole strength is okay for without washers. Below are our wheel building tips. 1. Normally, we use 3 cross lacing pattern for front & rear. 2. The strongest spokes that can be used on our rims are double butted 2/1.8/2mm. Straight gauge 2mm spokes are not allowed to be used on our rims or there is no warranty. 3. The maximum spoke tension of our rim is 180kgf. The recommendation of spoke tension is around 90kgf ~ 130kgf. Please check the wheels after a few days riding and adjust spoke tension if necessary. 4. Never use any sharp objects while mounting tires. Thanks, Light-bicycle

Is adding the HD necessary? What are you calling big riders? I weigh 200lbs. I don't do any downhill riding but would like to hit up some bike parks in crested butte and do Moab riding. Do I need the additional hd?
Light-Bicycle : (2016-07-13)
Hello Chase, Thanks for your inquiry. The HD version has extra layers for increased stiffness and sidewall reinforcement. Ideal for large and aggressive riders. Rider weight over 180lbs means large riders. If you don’t ride aggressively, then go with the AM version. RM29C14 (38mm width AM): 465 /-15g, $185/pcs Shipping with EMS is $50. All pricing in USD. Thanks, Light-bicycle

Can I run a 2.1 xc tire on the 38 wide (31inner) wheel?
Light-Bicycle : (2016-07-12)
Hello David, Thanks for your inquiry. The recommend tires size for 38mm rim are 2.3''-3.1''. If you like to run a 2.1'' tire, you can try our 34mm wide asymmetric rim. What your riding terrain is normally? Do you ride aggressively? Then we will double check which rim is more suitable for you. Thanks, Light-bicycle

jacko : (2016-07-09)
Hello, is there really a difference between heavy duty layer and without ? If the rim is strong enough without, why had HD layer which make the rim heavier ? I intend to use the rim for a front wheel in all mountain / enduro use. I go down hard, small gap and everything, but i never break a rim, and I always ride alloy rim like crossmax ST ( not the huge xt version). SO im guessing what the point with the HD layer.
Light-Bicycle : (2016-07-11)
Hello Choan, Thanks for your inquiry. We have received your messages and please find our reply as below. The RM29C19 is available for all mounting riding but not for aggressive riding or large riders. May I know your weight? Then we will check which rim is more suitable for you. The HD version has extra layers for increased stiffness and sidewall reinforcement. Ideal for large and aggressive riders. We will add some carbon fiber to enhance the rims' strength, with a heavier weight about 50g. Go with the heavier version and wider rims in your case as you are heavier and riding more aggressively. The additional reinforcement will handle g-outs more effectively. Thanks, Light-bicycle
