    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.

Weave This is a required option.

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.

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 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.

Looking to turn your road or tri bike into an aero machine? With a 55mm profile, the U55 is deep enough to give your an aerodynamic advantage without compromising ride quality in the stiffest crosswinds.


Comfortable as a race oriented wheelset or a daily driver, the 25mm outer width keeps things aerodynamically optimized with smoother rolling for your 25C ~ 28C tires.

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.

kevin Turley : U-shaped 55 tubeless ready DT Swiss 350 hubs and 3K finish on 2017 Specialized Roubaix. I am extremely satisfied with the build from light Bicycle. The wheels are flawless. Although I didn't make large gains in weight loss, the cool factor of my bike went up immensely. Thank Yo

Steve Bandy : Hoping for the best. Dallas, Texas has a large cycling community. A favorable review would probably go a long way here. Having the wheel built by a very good mechanic with top of the line bladed spokes. Will use it training and racing all summer. I only average about 250 km per week so not at upper levels but at 95kg and doing faster rides averaging 35kph it should be a good test of your product. As a salesman I do appreciate the effort your company puts into communicating with the customer before and after the sale. When the wheel is finished I'll get feedback from the mechanic on ease of build and let you know his initial opinion.

I’m concerned the 25mm rim width will not clear my Shimano brake calipers.


LightBicycle 2019/07/05

Hi Doug, ​ ​Sorry for the late reply. It was night time here when you emailed. I just checked on Shimano BR-R561. It is okay for 28mm wide tires. So, your brake calipers are wide enough for 25mm wide or 28mm wide 700C wheelsets. Thanks, Lightbicycle

What is the internal diameter of this rim(eyelet to eyelet)? I need this value for the Sapim spoke calculator. Thanks.


LightBicycle 2019/06/10

Hi Sir, The internal diameter of the rim is 523mm=633mm (OD) - 55mm*2(depth). You will also need the rim thickness for Sapim spoke length calculator, it's 3.5mm=[530mm(ERD)- 523mm(ID)]/2 Thanks, Lightbicycle

Andre 2019/05/08

Hello, what is the recommended nipple length for the 55mm deep carbon 700C 25mm wide rims? Thanks Andre


LightBicycle 2019/05/09

Hi Andre, Usually, we use 14mm length external nipples for RRU55C02 700C bike rims, 10mm for the internal nipples. BTW, we don't use washers while building, but you can use nipple washers if you don't might adding the weight. The spoke holes on our rims are drilled with a certain angle so the nipple can seat well on the inner side of the rim and align well with the hub flange angle. Thanks, Lightbicycle

Hi looking to buy rims only 55mm deep carbon clinchers can I do this and I want to put tubes in them 24/28 holes kind regards Tony


LightBicycle 2019/02/25

Hi Tony, It is okay to buy the 55mm depth 700C clincher rims in 24H/28H. Do you like UD matte and without brake tracks? It is tube compatible and also tubeless compatible. If you like to ride with tube, it is the same as normal rims and the same using. Thanks, Lightbicycle

Hi There, would you be able to share rim profiles for this model RRU55C and RRU45C? Also, do you have plans to make an 88mm deep rim with the new brake track in the 25mm width at brake track?


LightBicycle 2018/02/23

Hi Drew, We sent the rim profiles through email. Have you got it? Thanks, Lightbicycle

Meta 2018/01/23

Hi. -Could you manufacture this in a 'heavy duty' (HD) version too? How much weight would this add? -Internal nipple holes: Would this still allow tubeless tires?


LightBicycle 2018/01/24

Dear Meta I am Charlie from LIGHT BICYCLE. Thank you for your inquiry! Yes, we can make RRU55C02 as heavy duty version by adding extra material. Pls note that the rim would add 50g more weight and USD8 each. You can use tubeless tires on internal nipple rims. Rims with internal nipple will turn out like attachment.FYI, internal nipple holes diameter is narrow than external, it's about 2.3~2.5mm. Lightbicycle
