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?

When buying direct from China we found the best way was to use TPD delivery (Pre-paid duty) for our European customers. This way there are no charges upon receiving the product. Read more Delivery Methods to European Countries.

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!

Hi, I was looking over your TT/Track/Tri section and I could not see how I could build a set of track wheels... Obviously I looked at the Rim versions, but I did not see a track hub, or did I not look in the correct spot. I have a set of road wheels I love, and my fellow teammates have also purchased from you, so keep up the great work.. B Groves


LightBicycle 2022/08/01

Hi Bill, We understand that people usually build TT/Track with different type of wheel 700C for the front and rear. As you mentioned, you are interested in a pair of track wheels. Do you want spoked wheel or Tri-spoke for your front? What's the axle size of your bike? Thanks, Lightbicyle

I have a Specialized Allez smartweld e5 2016 frame with a maximum recommended tire size of 28 and would like to know if you have any experience on compatibility with the falcon pro wheelset, since it's width is 30mm. Thank you! Juliano De Bortoli.


LightBicycle 2022/05/03

Hi Juliano, Is the new AR565 the rim 700C you are interested in? There are 2 factors concerned with the compatibility of the wheel, The clearance of the fork and seat stays, and the limitation of the calipers. So, can you confirm the clearance and model of your calipers for me? The 30mm of AR565 is on the widest area (middle) of the rim. The wheel should be ok to mount on the calipers if the limitation is suggested 28mm. Thanks, Lightbicycle

Michael 2022/03/03

Hi... Am looking at purchasing a completed Mtn Bike wheelset for my existing hardtail. Mainly for amatuer XC, but also occasional bike packing. Price is a reasonable consideration, but so is light-weight. Am looking at either the RM29C06 or XC925. Some notes/questions below. Can you advise please: # I am 70kg & bike packing gear only adds 5kg. # Hubs must be QR & compatible to shimano disc (front could be 110 through-axle if need be). # Free-wheel for standard Shimano 10spd. # Can you price the lightest option in both these rims please? # And can you also suggest/price a good value for money trade-off between weight & price in both rim options please. Thanks.


LightBicycle 2022/03/03

Hi Michael, 1. The RM29C06 29er bike rim carbon fiber would make the lightest option. It's been one of our lightest and most popular rims since we introduced it to the market many years ago. It's from the Recon lineup, which is more cost-friendly 2. As for the hubs, DT SWISS would be easier to convert between sizes if needed. No special tools are required. But Carbon Ti hubs would make super lightweight wheels. But the conversion would be more difficult than DT hubs. We recommend converting the hubs to a bike shop if you are not equipped for it. Note that both DT and Carbon-Ti hubs have limits for conversion between sizes. 3. Please confirm if the hub size you want is 15QR(15/100), and 12QR(12/142). Thanks, Lightbicycle

Eric 2022/01/30

Hello, I am having a difficult time choosing between the R45 and AR45. I intend to run 700x28 or 700x30 tires with rim brakes for criterium and road racing. I understand that a wider rim profile generally proves more aerodynamic. My question is: would I benefit more from the toroidal shape of the R45, where the rim is wider (27.5mm) below the brake track (25mm) or from the V-shape of the AR45, where the rim is widest at the brake track (28mm)? Thank you for assistance.


LightBicycle 2022/01/30

Hi Eric, Thanks for your inquiry! For AR45 700C rim, the brake track widest is 28mm, but the rim middle body is with 30mm. it your bike wide enough? Is it your brake caliper wide enough for 28mm? Thanks Lightbicycle

Hi, I'm using a Cannondale Caad13 and would like to buy the FALCON WHEELSET AR46 DISC 700C Gravel-Optimized-Aero-Shape 46mm depth hand-built carbon road disc wheels - 28mm wide and tubeless compatible. For the rear wheel dishing pattern, which one should I choose? Traditional or Ai offset? If Ai offset is it the 3mm or the 6mm? Kindly advise. Appreciate your help. Thanks


LightBicycle 2022/01/15

Hi Azfar, I checked on the bike specs, there is no offset on frame at all. So, you can choost traditional wheel building. Or you can double check with your bike supplier or call Cannondale to make sure it is correct. Thanks, Lightbicycle

Elia 2022/01/13

hello I'm interested in your wheels but I have a few questions: 1- if I purcase from Italy and I choose TPD payments, it's sure will I not pay any extra money? 2- In the hubs ARC MT-032, is the freehub connected with pawls or ratched system like DT SWISS? 3- Probably I will buy falcon wr35 model, I'm 70 kg and I will use the wheels mainly for cyclocross and gravel. Is it safe to go with flyweight version or the standard will be better?


LightBicycle 2022/01/13

Hi Elia, ​ Please find our reply as below. 1. Yes, if you choose TPD delivery, you will not have to pay any extra cost(like taxes or duties). It is all included. 2. The ARC hubs we get are with the standard pawls, not ratches system. If you like ratches system, you can go for DT Swiss hubs. 3. Do you ride jently or aggressively? For WR35 32mm wide wheelset with standard version, they are with much more carbon fiber material, they will be more durable. Thanks, Lightbicycle

LightBicycle 2021/11/04

Hi Steve, For your weight 72KG, it is okay to ride flyweight version AR35 road disc rim 700C. Do you ride aggressively or gently? Normally 24H is strong enough. But if you like wheelset to be more stiff and do not mind the wheelset weight, it is okay to get front 24H/rear 28H. Thanks, Lightbicycle
