MOST FREQUENTLY ASKED QUESTIONS

F A Q

Can I purchase rims without holes on the center channel?

While it is possible to order rims without access holes, we prefer standard drilled rims. Rims with an undrilled bead seat are heavier and much more difficult to assemble or replace spokes. In our experience, a standard taped tubeless rim is equally effective while making it much easier to service and and the system weight remains lightweight. That said, if you really prefer rims without access holes, please contact us and we can do that for you by special order.

Can I get a custom spoke count? Custom angled hole?

We are able to custom drill any spoke count, and some rims can have a custom spoke angle. Please contact us, and we can consult our engineers on availability.

What is the difference on UD, 3k, 12k weaves?

The weaves are entirely cosmetic and do not affect the performance or weight of the rim significantly. Click this link to see the differences between three weaves.

How about your braking track on road rims? What temperature can it handle?

High TG Surfaces uses a special resin mixed with dry carbon fiber to create a unique carbon fiber layer. The resin is highly resistant to heat and can withstand temperatures of over 240 degrees Celsius. Repeated testing has shown that the braking surface is highly resilient to temperature changes and resists brake fade during extended braking.

Our latest upgraded Grooved Graphene Surface runs a 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.

How do I choose the best rim for my style of riding?

Road rims: Please see our guides for choosing the right road rim depth.

What is the difference between an asymmetrical and symmetrical rim?

Asymmetrical rims are designed and drilled to compensate for the offset design of most hubs. The asymmetry of the rim allows the spokes to equalize in tension between the drive and non-drive sides of the wheel. The result is in more even spoke lengths and a stronger wheel build which requires less truing than a traditional rim.

Symmetrical rims utilize standard drilling practices and do not compensate for the offset hub design. The result is a wheel build that may not be as strong as an asymmetrical build, but comes as a more cost effective option.

How are Recon Pro rims better than the standard Recon rims?

Our Recon Pro rims use a completely new mold design and new manufacturing process that allows the rims to come out of the mold as a finished product (no sanding & painting needed). The layers of carbon are not disturbed post-production which results in a stronger rim with a more scratch resistant finish. We use a new resin system with a lengthened fatigue life and superior consistency. The recon pro rims are more durable and made in new dust-free production line.

All of these improvements coupled with an updated asymmetric profile shape has allowed us to extend our standard warranty on these rims to 5 full years or lifetime warranty!

To learn more about the key differences between the Recon Pro and Standard Recon rims, have a look at the following page on our website.

What tire pressures should I run?

Carbon rims do not do well when the pressure is too low, or the pressure is too high. Unlike an alloy rim, which will dent, carbon rims will crack if the pressure is too high or if subject to a large hard impact when the pressure is too low.

While largely personal preference, there are pressure ranges that work well with each rim. The wider the rim or the larger the tyre, the lower the pressure required. The sweet spot for air pressure is not too low that you are frequently bottoming out the rim, and not too high that the tire is hard and uncontrollable. If you are riding more technical terrain than normal, it is a good idea to increase the air pressure a few psi to prevent bottoming out excessively.

Double checking air pressure before each ride is imperative to avoid excess rim strikes and poor performance. Ultimately, you have to consider your terrain, weight, riding style, tire choice, rim width, and use good judgement.

How can I get the spoke length for external hole rim or internal hole rims?

For external nipple builds (standard), you can use the ERD listed on the rim pages on our website. *Standard nipple heads only. If you are using nipples with a raised head like DT Squorx or Sapim/DT double square or hex nipples then you need to add 2mm to the ERD. As with ANY wheel build, the most accurate way to get the ERD is to measure it on your specific rims because the ERD can vary.

For internal nipple builds, generally speaking you’d need to add 8mm to the ERD.

Please contact us if you want us to calculate the spoke length, here is what we’d need to know:
Internal hole rim or external hole rim
Hub manufacturer name and model
Hole counts
Front and rear axle width
Straight pull or J-bend
Spoke lacing preference (2-cross? 3-cross?)
Nipple preference (If you are using nipples with larger heads double square, Squorx or Hex etc. then we will need to know as longer spokes are required!).

Can I send my hubs over for custom building?

Yes! Please email us before sending the hubs so we can create a purchase order and provide you with the appropriate instructions for shipping and payment.

Can I get custom wheels?

Yes, we have a significant amount of customization on our wheel building tools on our site! Please contact us if there is something missing from our builder and we’ll see what we can do.
Custom MTB Wheels: https://www.lightbicycle.com/custom-mountain-wheels.html
Custom Road Wheels: https://www.lightbicycle.com/custom-road-wheels.html
Custom Fatbike wheels: https://www.lightbicycle.com/custom-fat-wheels.html

For more custom wheels requirement, please contact us at sales@lightbicycle.com.

What tension should I build my light bicycle rims with?

Bring the spokes to an even tension, with a maximum tolerance 5% for all drive side and 5% all non-drive side. For our recommended spoke tensions, please see the chart below. During and after building, have the wheel stress relieved properly. If a spoke develops a sharp bend in it while building, please replace the spoke.

Spoke Tension Reference Chart:
We apply the following spoke tension range while building wheels.
Front wheel non-drive side Rear wheel drive side
Symmetric MTB/road disc wheelset 120-130kg/f 120-130kg/f
Asymmetric MTB/road disc wheelset 120-130kg/f 120-130kg/f
Road non-disc wheelset 100-110kg/f 125-135kg/f
*Make sure the max spoke tension is less than 135 kg/f on any spoke!

How should I lace my light bicycle MTB rims?

We recommend lacing the wheels with the outside spokes rotating forward in order to brace the braking forces common on disc brake wheels. Some companies build the rear for driving forces, while other companies use the Shimano method which is braking force (disc rear) and driving force (drive side rear). We have been successful using the braking force method and recommend you use the same, although the Shimano method is acceptable as well.

Typically we build 29er wheels 2x and 650b wheels 3x with 28h and 32h builds. A 2x build results in a laterally stiff wheel that utilizes shorter and lighter spokes which is why we use it in 29” builds more commonly. 3x is more traditional and results in a torsionally stiff wheel. Either method work well.

Are nipple washers required for wheelbuilding?

With Light Bicycle rims, nipple washers are not required.

Can spokes and nipples be purchased separately?

Sure! Please let us know which nipples you’re looking for. For spokes, we’d need to understand the length or wheel build specifics, and type of spoke you require so that we can ensure we have them in stock.

What is the weight difference between brass and alloy nipples?

The weight difference is about 50g for a 32h wheelset.
Brass: 1.09g/pcs
Alloy: 0.36g/pcs

How can I get the custom decal and how much does it cost?

For the custom decals, please email us a picture or describe what you would like. Generally speaking, it is USD65~$120 for graphic cost one color or two color graphic. It depends on decal size and color.

Our standard light bicycle decals are available at no charge.

Import and Customs fees are high for my country. Is there a way to avoid this?

How to check the correct orientation while building asymmetric wheel?

• Follow the spoke direction shown on arrow sticker.

The rims have angled nipple holes that alternate left/right/left. Please lace spokes in the correct direction to avoid spoke hole damage. The direction is shown on arrow sticker near the valve hole.

the spoke direction indicator on rim • Asymmetric rims building tips

For asymmetric rims, there are shorter and longer arcs. When viewing from the rim channel, it's easiest to find the shorter side and longer side by looking at the valve hole in relation to the nipple holes. Please make sure the rim is in correct orientation - It is different for front and rear wheels!

Front Wheels: shorter side for drive side, longer side for non-drive (disc) side

Rear Wheels: longer side for drive side, shorter side for non-drive (disc) side

Having trouble of mounting the tires?

Part of the problem you may be having is because you are using regular tires that are intended for use with tubes. Our rims are designed for tubeless tires and, as a result, the tolerances are a little different. Normal tires don't have as nice of tolerances on the bead diameter so it is really hit and miss on how they will fit on a tubeless rim. Some might work, but generally they will fit too tight and you'll be fighting it. The best bet would be to use a tubeless compatible tire and you could still use a tube in those if you want.

We have had customers emails about this challenge as they like to use a traditional favourite tire and they complained how tight they are. We bought the same tire they were complaining about and mounted it (by hand without levers) on their exact rim that they returned and showed them a video of us installing it just fine. It takes some technique to install tubeless tires and even riders who have been installing tires for 20+ years could have a problem. They are used to installing tube compatible tires on non-tubeless rims which does not qualify as experience or even the technique used when installing tubeless tires. We actually sent a number of rims to Schwable to see if this was going to be a problem and each one of them came back rated as "Simple, By Hand" when it came to mounting the tire.

Tubeless carbon rims are made with tight tolerances, and unfortunately clincher tires are not. So if you are willing to change to tubeless tires and ride those if you find your current tires prove to be too much of a struggle, then that would be a safe bet.

We hope this helps!

Why are the hub costs under the North American Options so much more expensive than for under the Global Options (China warehouse)? I am looking at the Falcon Pro AR46 - 28mm wide wheelset and selecting the DT 240S hub increases the cost by: Global Options: $220 North American Options: $600 The base cost of the wheelset is $107 less under the North American options but the same hub is $380 more. Why the difference?


LightBicycle 2020/05/08

Hi Craig, Yes, the DT hubs are quite different in two warehouses. We purchase DT hubs from DT SWISS in bulk here, so the cost is lower. As for the North America warehouse, we purchase the hubs in a small amount from the DT US branch because some people prefer the faster shipping that Canada warehouse offers. With the tax adding, we really don't have much benefit space. If you are not in a rush, ordering from the Global warehouse would be a better deal. Could you tell me what configurations that you are interested in? Or do you prefer to place the order online by yourself? Thanks, Lightbicycle

Can you tell me the difference between Falcon and Falcon PRO wheelsets. Thanks


LightBicycle 2020/03/12

Hi Scott, The production process is different between the Flacon and Flacon Pro series. The Falcon series is made by the traditional process with a high standard quality control management. The Falcon Pro series production process was re-designed from the material, layup, molding to spoke drilling (aviation drill) to make the rims come out of the mold as a finished product. The scratch resistance ability is significantly improved, the rims are also more durable. Thanks, Lightbicycle

Hi Jenny, Are any of your rims or wheelsets tested with ebikes (electric motor bikes mid drive)? If so, which wheels in 29er or 700c are strong enough for an ebike? Have you tried a Bafang 750 or 1000 watt motor with your wheels? Thanks


LightBicycle 2020/02/05

Hi Nick, we can customized manufacture the 29er or 700C rims with some more carbon fiber material added, to make them stronger for your E-bike riding. Quite a few customers use our rims on E-bike,they are durable enough. Thanks, Lightbicycle

Hello, I am preparing for a 150km very hilly Gran Fondo (2500 m elevation gain and loss) . I'm new to this level of riding and looking for every bit of help! Do you have advice about what would be the best wheel for this type of ride? I weigh 75 kg and consider myself pretty aggressive (though getting old!). I think it may also be fairly windy in places. I was looking at the AR46 wheels (disc 28mm) - thinking it's a good all around choice. But then there is also the R45 (25mm) which might be stiffer? Any thoughts or suggestions would be most welcome. Also, any updates coming that might be of interest?? Thanks!


LightBicycle 2020/01/26

Hi sir, Thanks for your reaching out! May i know your tire width please? Then we can check whether AR46 28mm wide disc wheels are better or 25mm wide. AR46 wheels are wider and deeper, it is stiffer than R45 25mm wide disc wheels actually. If you prefer stiffer wheels, you can also go for 28H spoke count, or front 24H/rear 28H. Thanks, Lightbicycle

Are you able to source straight pull bitex hubs? I would like to use the r55 rim with cxray spokes. If possible I would like a 2 cross for the rear on both left and right sides. I am heavier at 107kg. Or are your stock wheels adequate?


LightBicycle 2019/10/15

Hi Randy, Are you looking for R55 700C wheelset with disc or non disc brake system? Then we can check which straight pull Bitex hubs we can get. For 107KG, it is not a very large rider. Max rider weight limit is 135KG on R55 wheelset. Don't worry. Thanks, Lightbicycle

Seb 2019/09/06

Hi LB Team, I am considering WR38 and WR50 to build a set of wheels, but I am hesitating between both. I would like to have your advice. I am a 87kg rider, doing 8000 km per year from short (50 km) trainings to long (1200km) bike trip. No race. I am looking for a set of wheel that could handle both tyres : - 28mm for fast pace short ride (and a bit of aero gain) - 35mm for long distance bike packing trip (that include some off road tracks). WR50 or WR28 ? Thanks


LightBicycle 2019/09/06

Hi Seb, Thanks for your inquiry. Is there any climb road through your bike trip? If not, you can go for deep wheels(WR50). If there is quite a few climbing area, then go for WR38 to save some weight. And you can go for front 24H/rear 24H for your wheelset. You are not a large rider. ​ Thanks, Lightbicycle

Hello Hesitating between : https://www.lightbicycle.com/35mm-wide-29er-rims-beadless-for-bicycle-trail-or-mountain-bike-enduro-with-tubeless-compatibility.html And https://www.lightbicycle.com/AM930-asymmetric-rim-profile-carbon-29-inch-carbon-rims-mtb.html Same inner width and (almost) same weight. I'm looking for lightness and lateral stiffness (precision), but want to keep the ride comfy. So which one is vertically the most compliant, meaning which one is the less harsh to ride ?


LightBicycle 2019/04/30

Hi Laguite, Thanks for your inquiry! If you do not prefer mtb wheels too stiff, AM930 is better. AM930 29er bike rim is with new technologies, Our Recon Pro rims use a High-grade customized epoxy resin in the prepreg, which creates an incredibly stable base for our rims. Epoxy is less brittle than polyester resins and offers far better flexural strength. This consistent resin system coupled with a precise layup schedule offers the most reliable and durable product we’ve ever created. Thanks, Lightbicycle
