Valve Stem This is a required option.

We include enough valves to cover your individual rim purchase. We use a lightweight black alloy anodized valve with an oversized concave collar for easy gripping. A rubber o-ring goes in between the rim and the collar to help seal the rim and match the contour of the rim profile. The vavle core is removeable so you can add sealant withoutn removing your tire.

Tubeless Tape This is a required option.

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.

Wider, stronger and stiffer. When aggressive riding is in your DNA, the 933 is the rim answering the call. With a wide profile, this rim is designed to work perfectly with the new breed of ultra wide trail tires. This huge air volume will give you stability and an insane amount of traction that will encourage riding in the nastiest of conditions. The ability to safely run lower pressure while enjoying the lightweight, quiet and dampened ride carbon provides, will have you shredding the trails like never before.


This rim comes in two different layup styles. While the standard layup is suitable for most riders, the EN version features an extra layer of 3k carbon for heavier riders, or those notoriously tough on equipment. Not only does this help support G-Out forces, but it also makes the EN933 one of our stiffest options.

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


T700: Constructed with premium Toray T700 carbon fiber. The best strength to weight ratio with no expense spared.


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.


Asymmetrical: The profile allows for equalized spoke tension which creates a stronger wheel that stays true.


Tubeless: While the rims are optimized for a tubeless setup with the addition of tubeless tape, they also work with tubes.


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.

Hi, when shopping for rims is the price for one rim only or a set?


LightBicycle 2018/12/11

Hi Gary, The price is for one single 29er rim. Thanks, Lightbicycle

Could I use this rim for e-bike ? if I go with the EN layup ? total weight of rider and bike about 108kg


LightBicycle 2018/11/10

Hi Duncan, This rim in EN version will be strong enough for E-bike. May i know what spokes and hubs that you will use? Is the spoke 14 gauge? Then we can check more detailly for you. Also, we will have E-bike models of rims/wheels in 2 months. If you are not urgent, you can wait for E-bike models. Thanks, Lightbicycle

1) Is it possible to have holes drilled only in the inner wall of the rim, so only in the side facing the hub? I'm aware that it's a pain to build the wheel in this way, routing nipples through the valve hole, but when done, I get an UST rim, also a bit stronger. 2) Offset is a value mandatory, or you can drill holes also with 2.5 mm offset instead of 3 mm?


LightBicycle 2018/10/27

Hi Riccardo, Yes, we can make a UST rim for you with no extra cost.The holes usually lie in the channel center, and the drilling is with +/-6 degree angle. Do you mean you want the drilling hole to be laid offset on the rim bed? Normally, we would make offset drilling on the plus or fat bike rims. This 29er rims profile is with 3mm offset. Do you mean drilling the spoke holes 2mm offset from the rim center line? Thanks, Lightbicycle


R

Riccardo 2018/10/27

It's highly welcome to have +/- 6 degree angled drills, why don't you declare it in rim description? It's a plus for it! I've no way to provide you an attachment, with a picture it'd have been much more clear, so, lease, look above in product page at black&white drawing with rim dimensions. I mean: don't do any hole at all on the side where there is "33" (this is already agreed by your answer) and apply a value of "2.5" in place of "3" on bottom side, the same for all holes of both DS and NDS. I'm just asking if the 3 mm offset can be reduced to 2.5 mm, without weakening the rim. I think that the answer depends on how the rim is built: if (1) in the area around the drill carbon thickness is constant for a while, and (2) you can easily apply this mod to the drilling machine configuration, it can be done. If instead carbon layer thickness decreases sharply when you leave the 3mm center spot, drilling 0.5 mm laterally from the center would reduce rim strenght, as that's also may be the most critical area of the rim. The reason for this request is that I'm going to use an hub with just 5 mm of difference in left and right flange distances from center, and I'd like to apply this uncommon feature to create a perfectly balanced wheel, but I need an asymmetric rim with an offset of just 2.5 mm. Your rims with 2.5/2.6 mm offset are all smaller than this one, that as the perfect measures I'm looking for, as I'm going to build an Enduro wheel tailored for 2.6" tyres.


LightBicycle 2018/10/29

Hi Riccardo, Great! We will list +/-6degree drilling on rim specs ASAP. This 29er rim is wider, so with 3mm offset profile design. If you like 2.5 mm offset drilling, we can work on the spoke holes with 2.5mm offset from the rim center line. I just sent an drawing about the drilling. Is it what you like? Thanks, Lightbicycle

Guillaume 2018/09/11

I’m interrested by the EN933 rims for tandem bike. But the weight that our bike will support is approximatly 150kg and the maximal weight that your rims support is 125kg. Do you think that it will be possible to chose it or it will be needed to taje something stronger ? Thank for your advice


LightBicycle 2018/09/15

Dear Guillaume, The weight limit is usually referred to the rider weight. If you are under 125kg, the wheelset would be ok for you. If you are doing aggressive riding or you want to reinforce the wheelset just in case. You can use round spokes and stronger hubs while building the wheelset. All in all, if you are lighter than 125kg and not doing very aggressive riding. 29er rims EN933 (enduro version) will be strong enough for you. Thanks, Lightbicycle

I am interested in the en933 rims matte UD with 32 holes are these available from the European warehouse?


LightBicycle 2018/08/06

Hi Huw, Sorry, we don't have EN933 29er rims stock in Europe warehouse currently. If the import tax is the main issue that you worried about. You can choose our TPD (tax-prepaid delivery) for shipping. You won't have to pay any import tax. Thanks, Lightbicycle

Hi if I place my order tomorrow how long till I received my rim? I will need it by Monday if next week. I'm going on a trip and need it asap. Please help. Do you ship from US? Thanks Eddie


LightBicycle 2018/07/05

Hi Eddie, Since you request the rims urgently to US. You should place the order from our North American site and make contact with our North American base colleague. But you should note that the US base only stock with the standard setup (UD, matte, 32H). Special orders are ordering to make. If your order is not UD matte 32H, normally it takes around 10 days to manufacture in China, and another 5~10 days for delivery. Thanks, Lightbicycle
