OVERVIEW

RIM

Brake system This is a required option.

Non Disc USD +30

Disc

Non-disc: Our new resin system and construction method, combined with the 3k rim track, withstands over 280°C, dissipates heat, and lowers rim temperatures faster in between braking efforts. Gain confidence-inspiring brake performance on the steepest descents and wettest conditions with our matching brake pads. Also, graphene added to the rim brake track allows for greater resistance to overheating with improved heat dissipation and reduced temperature accumulation during heavy braking. The grooved track helps evacuate trapped moisture between pad and rim in wet conditions, and brings more resistance and force at the lever when conditions are dry.

Disc: The disc version does not have a rim brake track and features a unique disc specific layup process. Our new layup is about 10g ~30g lighter by reducing the unnecessary material and utilizing elements of our Flyweight construction method.

Hole This is a required option.

Please note that our valves are drilled for presta and spoke holes are made for external nipples only. If you have a custom drilling requirements please e-mail us and we'll send you a purchasing link.

Finish This is a required option.

glossy

matte

Matte is slightly lighter and a more subtle finish (most popular). Glossy has a shine to it.

Weave This is a required option.

12K

The layup schedule is predetermined for each model, but you can choose the outer layer.
3k/12k/UD are the 3 choices for cosmetic appearance.The rim strength & weight is virtually identical.
UD Matte is the most popular and has a subtle look.
3k weave has a more traditional carbon fiber look.

Decal This is a required option.

stealth

blue

green

magenta

orange

red

white

yellow

Road rims use super light waterslide decals (glossy black). The decal is very thin and applied under a clearcoat so they are non-removeable.

Valve Stem This is a required option.

None

Add Valve Stem USD +7

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.

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.

Brake Pads This is a required option.

None

Add Brake Pads USD +10

4 pads will be included. These high performance brake pads are designed for carbon bike rims only and offer excellent stopping power even in the wet.

WARRANTY

Whether you’re chasing KOMs, racing criteriums, or preparing for your first Gran Fondo, the U35’s are ready to take you to the next level. The deep profile is easy to handle in crosswinds, and comfortable to ride on rougher roads or rolling terrain.

Coming in at only 435g per rim, the U35 is designed to help you soar up the climbs while still given you that aerodynamic edge when the road becomes flat. The 17.9mm internal width works with anything from a 23mm to 33mm road or Cyclocross tire.

High TG: Our new resin system and construction method, combined with the 3k rim track, withstands over 280°C, dissipates heat, and lowers rim temperatures faster in between braking efforts. Gain confidence-inspiring brake performance on the steepest descents and wettest conditions with our matching brake pads.

Graphene Brake Track : Graphene added to the rim brake track allows for greater resistance to overheating with improved heat dissipation and reduced temperature accumulation during heavy braking. The grooved track helps evacuate trapped moisture between pad and rim in the wet, and brings more resistance when conditions are dry so less force at the lever is required.

AeroTek: Our latest aerodynamic profile decreases lateral wind resistance and is both more stable and faster in a crosswind. A wider profile allows for larger and more efficient tires to be used without an aerodynamic penalty. Traditionally a tire can form a lightbulb shape when mounted on a narrow rim, but the airflow is much smoother with our wider rims.

DuoTek: Our clincher rims are manufactured in two pieces and then joined together. When designing the rims, our engineers, in every detail, demanded fewer joints. Fewer joints mean higher strength and stability.

TuffTek: A high-grade customized epoxy resin is used in our prepreg, creating a stable base for all of our road rims. Epoxy is less brittle than polyester resins and offers excellent flexural strength. Our consistent resin system, coupled with a precise layup schedule, allows for an extremely reliable and durable product.

Tubeless : All of our rims are tubeless compatible with bead seat retention. In most cases a floor pump is all that is needed to seal our rims. The bead shape is tailored to each rim width to achieve the best fit. Our hookless and clincher profiles have a smooth radius to reduce the chance of a pinch flat.

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

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.

Raph Leal : Finally, the project is done! Final weight: 6.8kg Wheelset weight: 1326.5g From Ipatinga, Brazil Tutano Bike Store

Brazil

Robert Clark : I LOVE these new wheels from Lightbicycle.com. Stepping up from my alloy rims, I am riding a full ten percent faster from day one. My bike accelerates way faster now also, and I am generally able to be much more aggressive on it (which is helpful because I commute through Beijing traffic to work ;-) ). These wheels are definitely worth the money, and I will buy from this company again when I am ready to get carbon wheels for my daughters once they are ready to start riding on road bikes. On top of a stellar product, Lightweightbicycle.com has stellar customer service to match. Lightweight Bicycle's responsiveness to customer concerns is hard to find in any industry.

Tom 2018/11/01

Hello Can you recommend this rim (no Disc) for riding in the Alps with 10 Percent roads and more?My wheight is 70kg, does your Graphene work?

LightBicycle 2018/11/02

Hi Tom, Yes, we do recommend our new graphene grooved brake track. 1) Compared to old brake tracks, the new brake surface's braking friction has improved 15%. 2) The temperature of old brake tracks can reach around 240 Celsius. But our engineers told me that we will use new high TG resin on your current road rims also, so it can reach around 280 Celsius for your current and future orders also. For new brake tracks, graphene added to the rim brake track allows for greater resistance to overheating with improved heat dissipation and reduced temperature accumulation during heavy braking. 3) Heat dissipated with the new surface has been improved by 8%. Thanks, Lightbicycle

Tom 2018/11/04

Thanks,and the grooved brake track (Texture) is standard on this Rim or only for more money?

LightBicycle 2018/11/05

Hi Tom, For graphene grooved brake track on RRU35C02 road bike rim, the price is USD199 each. It is USD30 higher than disc verion. Thanks, Lightbicycle

Mihai 2018/09/17

Hi there, is it any time soon that you will build a u shaped rim with a depth of 35 to 50 mm, but much wider, around 24, 25 mm inner width? I recently rode a pair of Enve SES 4.5 AR DISC, owned by a crazy enough friend of mine, and they basically convinced me to have a pair of wider wheels. Cornering it's simply amazing, rolling just as. I'm interested in these two; RRU35C02 and RRU45C02, willing to build two pairs of this at your work shop, with dt swiss and pilar maybe, but they have to be that wide. So any chance for that to happen?

LightBicycle 2018/09/17

Hi Mihai. Since you are after a wider and deeper rim profile. Our new RR56C02 (23mm inner/30mm outer width, 56mm depth) might be the closest rim for you. We can build it with DT SWISS hubs, yes. Or you can check out the wheelset configurations at https://www.lightbicycle.com/700C-V-shape-46mm-depth-hand-built-carbon-road-disc-wheels---28mm-wide-and-tubeless-compatible.html We will discuss more details with you by mail.

Hi Guys My local wheel builder recommended to you, have question, can you have spoke arrangement like campag rear 55mm 21spokes tubeless and 45 mm front 16 spokes straight Pull ,Dt hubs will it be strong enough Regards Peter

LightBicycle 2018/07/25

Hi Peter, For rear 21 spoke count RRU55C02 rim, is it 2:1 drilling? Do you like road rims only or complete wheelset? Thanks, Lightbicycle

Milan 2018/07/07

Hello, please, is 24 spoke enough for 90kg rider on rear wheel? Endurance and light gravel riding. Thanks

LightBicycle 2018/07/09

Hi Milan, If you are no riding aggressively, you can go with 24H. The max rider weight for RRU35C02 road clincher 700C rim is 135KG. We use over 300kg weight to do the test in our lab. You can choose Sapim CX-Ray to reinforce the wheels when you building the wheel. Thanks, Lightbicycle

Phil 2018/01/02

Hi, I'm looking to buy a set of 35mm rims and have a question about the decals. What comes as standard? I like the subtle square 'LB' logo over the valve stem but I'm not a fan of the huge graphic around the rim. Do you have a representative photo of what would be supplied if i ticked the option box for the logo? Thanks

LightBicycle 2018/01/02

Hello Phil, Thanks for your inquiry. RRU35C02 (clincher): 435+/-15g, $163/pcs We have newest road decal also. If you like the small logo on the value hole, that is fine. Pictures attached for your reference. Thanks, Lightbicycle

Larry 2017/11/22

I am looking at purchasing some rims to build up some road wheels and was curious if you rims need nipple washers and what is the max spoke tension? thank you Larry

LightBicycle 2017/11/23

Hi Larry, Our spoke hole is strong enough, so you don't need to add nipple washers. Normally, we do not make the spoke tension higher than 135kgf while building wheels. Thanks, Lightbicycle

Brian 2017/08/08

Is it possible to have spoke hole drilling for triplet spoke lacing? I plan to build 24/24 hole triplet wheelset. Every third hole would need to be drilled angled toward the non-driveside rear, and non-disc side front. The key spoke holes on either side of the valve would need to be angle drilled toward the drive side rear and disc side front. This would be the same lacing pattern of all Industry Nine road/cx wheelsets, for example. Thanks!

LightBicycle 2017/08/09

Hi Brian, For the triplet spoke lacing, is it 2:1 drilling? Are all spoke holes evenly spaced on the rim? If yes, we have two drilling as attached. Which do you prefer? Is it the method B? Are both front and rear rims with the same drilling pattern? Thanks, Lightbicycle

dams 2017/07/06

Hi, What is the maximum pressure for a 25 mm tubeless ready tire ?

LightBicycle 2017/07/07

Hi Dams, Thanks for your inquiry! For road RRU35C02 rims, it can fit 25mm tubeless tires and the maximum pressure is 160psi. However, while riding, normally, riders will make the tire pressure around 100~130psi. Please check our quotation as below. RRU35C02 rims: clincher, 25mm wide/35mm deep, UD matte? Front 20H/rear 24H? With brake surface(or not for disc)? With decals or not? USD163 each Thanks, Lightbicycle
