    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.

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.

At only 475g with an aerodynamic 45mm deep profile, the U45 is our jack-of-all-trades rim. Whether you are chasing KOMs on the mountain or racing your buddies to the next checkpoint, this rim is for you.


With a 45mm depth, this rim offers all the aerodynamic benefits of a much deeper profile in a lighter package that’s easier to control in crosswinds. If there’s climbing to do, these could be your best choice.

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.


Pro Series: from date of purchase, 3 years warranty
Non-Pro Series: from date of purchase, 15 months warranty

Crash Replacement: from date of purchase, 30 months with 10%+ discount subject to rim model

Look695UK Edition 100miles : I agonized over what wheels to put on this frameset for months. I wanted carbon and tubeless. There are not many to choose from. I have always built my own wheels, I ran a shop for almost 20 years and have built hundreds of wheels over the years. I chose these as several of my friends run their carbon MTB rims and have been flawless. I opted for these purely based on the timely responses to all of my questions. I built them up over a snowy weekend. Laced them with different color nipples untill I decided on red alloy nipples. Sapim CX-Ray Aero spokes on Hope Hubs ( love Hope, have everything they make on all my bikes) Front went together easily, the rear was a pain. I had a hell of a time making it perfectly round. I go to 0.5mm on my truing stand, and had a hard time meeting that number. Once built, I was very impressed with the weight, 1459g for the pair. They look fantastic on the bike, and I'm now toying with building up a second set in the 45mm depth. Then I can switch them out between my 2 road bikes. ( my other is a custom Titanium) As for the ride, I have only put 100 miles on them, I am running Schwalbe Pro One 700x25C tires with stans sealant, orange seal rim tape and WTB ally valve stems. The rims are 25mm wide, this actually pushed the tire out to 28.4mm width. So this makes the ride very plush, but without the squishyness I feel on my standard conti GP4000's. The overall feel of the bike is of speed, yet with a layer of comfort I have never felt on a road bike before. The wheels are stiff ( I weigh about 160Lbs ) super responsive, no flex, and using Reynolds cyro pads, no howling from the brakes. Infact the braking is excellent, although I have yet to try them in the rain. Of course it is still early days, but overall I am very impressed with the product and would absolutely recommend anyone to try them.

James 2018/09/23

For US customers can I get the U45 in a 28 hole drilling? I on;y see that option for international buyers.


LightBicycle 2018/09/25

Hi, James Yes, you can have 28H rims from our North American warehouse if you like. Note that the reason why you cannot find the 28H at the North American warehouse is that we don't have stock for this rim. So the rim would be ordered to make from our factory and takes about 3~5 weeks. My suggestion is to order the rims you want directly from International (China )warehouse to save the time. Because we have last two 45C02 (25mm wide, 45mm deep with UD, matte, 28H, with brake surface ) in stock currently, which means you can get the rims in 7~10 days. We can discuss more details by mail. Please check with your inbox for our reply mail. Thanks Lightbicycle

Hi, Can you do road rims with hole for internal nipples ?


LightBicycle 2018/09/25

Hi, David Yes, we can drill for internal nipples. the spoke hole diameter would be 2.5mm. And we won't charge extra for this. If you like to order the rims online, you can leave a message during checkout. If you like us to handle this for you, we can discuss further details by mail. We already sent an e-mail to you, please check your inbox. Thanks Lightbicycle

Rob 2018/08/07

Do these rims have groves on the brake surface similar to how other companies are doing it now to improve braking in all conditions? If not, are you planning on adding them in the future and when?


LightBicycle 2018/08/08

Hi Rob, Yes, we already have texture on rim brake surface on road rims. We will revise our website accordingly late this month or early September. Thanks, Lightbicycle

Mark 2017/07/10

I have a rear hub with an asymmetric spoking pattern - 16 spokes on the drive side and 8 spokes on the non-drive side. Can the angled spoke drilling be done to accommodate that (i.e. a 2:1 ratio of left-to right holes?).


LightBicycle 2017/07/11

Hello Sir, It is okay to drill 2:1 pattern for you. Are all the 24 spoke holes evenly spaced on rims? For attached two 2:1 drilling, which do you prefer? Thanks, Lightbicycle

Tyler 2017/04/10

I'd like to build a 45mm U shaped wheel (24 holes) with a Powertap GS or G3 hub. If I order the rim and spokes through you, would you be able to supply spokes at the correct length so I can build it out? Thanks, Tyler


LightBicycle 2017/04/11

Hello Tyler, Thanks for both of your support. Currently, only Novatec and DT Swiss non-disc hubs are available, not Powertap hubs. Sorry about that. Or you can order the rims only and build the wheels at your local shop. Then you can get the hubs you like for wheels building. Does that work for you? Thanks, Lightbicyle

Joao 2016/10/24

Hi there I have a pair of ZIPP 404 (60mm) 2008 clincher wheels. The rear rim split some time ago, had it repaired but now plan to replace the rims. After looking through your website, I am thinking of replacing them with the U shaped 45mm depth clincher rims. Will have a chat with the pro at the local cycling shop, but do you supply spokes that are compatible with ZIPP hubs? Moreover what size tyre is suited for these rim, 25mm


Light-Bicycle 2016/10/25

Hello Joao, Thanks for your inquiry. Our U45mm rims will work with ZIPP wheels. 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. Also, please confirm the spokes length with your local builder, then we will check if we have the spokes length in stock. Thanks, Light-bicycle

Hi, Is the hole is oriented so yes can for mounting 2:1 ? You can have sapim super cx-ray and cx-sprint ? TY, Damien.


Light-Bicycle 2016/10/13

Hello Damien, Thanks for your inquiry. Our rim is with angle hole drilling. For 2:1 drilling, we have to manufacture your rims separately, and make the rims with 2:1 drilling accordingly. Please find attached pictures of this special drilling, which do you prefer? Recently, only Sapim cx-ray is available, not Sapim cx-spint. Thanks, Light-bicycle

Hi: I am looking for a 25mm internal width carbon 700c rim for disc brake. 35mm to 45mm deep and tubeless. Enve are now making them - do you have plans to make them too?


Light-Bicycle 2016/10/14

Hello Panda, Sorry for the late reply. We were on National Day vacation during Oct 1st ~ 7th. Yes, we have discussed with our engineers and will have a plan to manufacture the wider road rims for disc brake. I will keep you posted on this new rim. If you need the rims urgently, our 30mm outer/ 24mm inner 29er mtb rim is suitable for cyclo cross bike also. Thanks, Light-bicycle
