    OVERVIEW

RIM

Brake System This is a required option.

Road-Rim-High-TG-Surface-Grooved-Graphene-Surface

Non Disc - High TG Surface: Rim Brake 700C road rims use an advanced High TG resin system with a layer of graphene to help dissipate heat. The braking power and reliability is significantly improved over a basalt braking surface.

Non Disc - Grooved Graphene Surface: 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.

Decal This is a required option.

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.

We include enough valves to cover your individual rim purchase. We use a lightweight black alloy anodized valves 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 valve core is removable so you can add sealant without 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.

Weighing in at only 405 grams, the R25 is built to fly up the climbs like never before. Our lightest road option will have you chasing KOMs and personal bests every time the road begins to tilt upwards.


The New Gen Aero shaped 25mm deep profile is easy to control in crosswinds and comfortable on long rides. The 17.9mm inner width is a great match for a 23mm road tire, a 33mm Cyclocross tire, and everything in between.

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. At this stage, with this newest brake track, you could order road Non-disc rims only directly online, however, please contact us at sales@lightbicle.com if you want to order a complete wheelset with that.


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, 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, would this carbon 25x25 rim work for a 77KG rider (me) with extralite hubs? (hd front, sl-2 rear) in 28/28 configuration (28 spokes front and rear). for a vintage pinarello treviso from the 1980s. how stiff are these 40xg rims compared to equivalent aluminum? also, do you make an asymmetric version of this lightweight rim? if not, how do i have my LBS lace the hub/rims to equalize tension on the NDS of the rear wheel? lots of questions i know.


LightBicycle 2019/05/06

Hi Andy, 77kg is considered a lightweight rider, so yes, the wheelset road disc 25mm wide WRU25C02 (25mm wide*25mm deep) that built with Extralite hubs will strong enough for you. Double check with you, the hubs you want is Extralite CyberFront HD and CyberRear SL-2 with 28H spokes. Correct? Stiff is the key feature of carbon rims, many of our customers never go back to aluminum. All of our road rims were designed to reach the balance of lateral and radial stiffness to make sure the confines and stiffness during riding. Stiff is not the only factor would affect the riding performance. We also adding Dynamic Speed Balance to our rims from the very beginning of the manufacturing process. We will also consider this while wheel building, so the best way to gain nice performance is to purchase the full wheelset from us including the valve and tape weight. We don't have the asymmetrical version of the specific rim, but we do have an asymmetrical road rim RG922 (29mm wide, 28mm deep, 2mm offset ) gravel bike wheels available. The tire width recommendation range is 23~50c. Let me know if this rim fits your request. Thanks, Lightbicycle

Hello. Will you let me know if there is the side designation of the rim with graphene brake track? Thank you, Hiroshi


LightBicycle 2019/04/01

Hi Hiroshi, We can add the new graphene brake surface to all 700C road rims. the one you are looking at RRU25C02 (25mm wide, 25mm deep) certainly is doable as well. The rim would be USD177 with the brake surface. Thanks, Lightbicycle

Hans 2019/02/03

I’m thinking about reusing my DT R1700 hubs. Front 18 and rear 24 spokes. Is this possible and what would this set of rims aprox. cost?


LightBicycle 2019/02/04

Hi Hans, Thanks for your interested in our rims! Are you interested in RRU25C02 rims(25mm wide/25mm deep)? The cost is as below. You can order two rims and rebuild on your DT hubs. RRU25C02: clincher, UD matte, front 24H/28H, with high TG resin brake surface, no disc, USD147 each If it is with graphene grooved brake surface, the rim cost will be USD177 each. The delivery cos is USD68.1 for two rims to Netherlands by EMS delivery. It is USD89.1 by TPD delivery. TPD delivery is tax prepaid. You will not have to pay tax or VAT by TPD delivery. Which do you prefer? Thanks, Lightbicycle

Hans 2019/02/04

Thanks, been investigating what I would need on my existing DT SWISS R1700 hubs. Can you inform me about the size/type of the Sapim CX spokes that need to be used with the RRU25C02 in combination with the R1700 hubs?


LightBicycle 2019/02/05

Hi Hans, If you like our help to get the spoke length for RRU25C02, you will have to wait for a few days. We are on Chinese New Year vacation from Feb 3rd~Feb 11th. Is that okay? Are your hubs straight pull or J-bend? Front 20H/rear 24H? Then we can check with our wheelbuild engineer on the spoke length for you on Feb 12th. Thanks, Lightbicycle

Hi, Can I use the bladed spokes on this rim or in general in other rims? Thanks.


LightBicycle 2018/12/29

Hi Nicola, You can use the blade spokes for all road wheelsets. What we offer is the Sapim CX-Ray spokes, it's lightweight, durable and aerodynamics. Will be a great option for road wheels. Do you want to build a complete wheelset from us? Our wheel builders are very experienced and skilled. Thanks, Lightbicycle

Nicola 2019/01/02

I have a bicycle repair shop...so, I want to start to build my own wheels with my brand...do you have some asymmetrical carbon rims for road bike?


LightBicycle 2019/01/03

Hi Nicola, Yes, we do have asymmetric road bike rims available. You can see the rim profile from the attached picture. What rim depth do you prefer? Thanks, Lightbicycle

Isco 2018/11/20

I am interested about your rims in youtube, can this rims 25mm for 85 kilos i look in your spec max 110 kilos , can this rims use dt swiss competition Thanks for your attention


LightBicycle 2018/11/24

Hi Isco, We have built a lot of wheels with DT Swiss competition spokes for our customers, but only MTB wheels. Usually, we don't suggest using round spokes for a road wheel. For one it would certainly gain some weight. On the other hand, it would too stiff and lack of aerodynamics. Most people go with bladed spokes. We offer Pillar Aero X-TRA 1420 and Sapim CX-Ray spokes for most of our road wheels. Will them be ok with you? If you prefer using DT spokes, they also provide bladed spokes, we can check if we are able to purchase them for you. Your weight is ok to ride on our RRU25C02 (25mm wide, 25mm deep) 700C road rims. Thanks, Lightbicycle

Cris 2017/05/12

Would the 24c02 be a good idea to set up tubeless for an sworks tarmac???


LightBicycle 2017/05/15

Hello Cris, Thanks for your inquiry. Some of our customers gave us the feedback that it is a little difficult to do the tubeless setup on RR240C02 rim. So we’d like to recommend the 25mm wide U shape 25mm rim which is easy to setup tubeless tyres. You only have to use tubeless tape, sealant and tubeless tire. Then the rim can ride tubeless perfectly. Also, the wider rim is much stronger. Thanks, Lightbicycle
