1. 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.

2. Can I get a custom spoke count? Custom hole angle?

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.

3. What is the difference on UD, 3K and 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.

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

Our latest braking surfaces use a special high TG 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.

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

Please use our comprehensive product filter tool to select the best rim for you! You can also contact us to discuss your personal situation so we can make an accurate recommendation.

6. What is the difference between a symmetrical and asymmetrical 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.

Both rims come with a 15-month warranty. The asymmetric rims have a 30-month crash replacement policy at 25% discount, while the symmetric rims have a 15-month crash replacement policy at 15% discount. Know more about the warranty details.

7. What tyre 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.

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

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!)

9. Can I send my hubs 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.

10. 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.htm

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

11. 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!

12. 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.

13. Are nipple washers required for wheelbuilding?

With Light Bicycle rims, nipple washers are not required.

14. 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.

15. 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

16. 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, 65 USD roughly is added for this service. Our standard light bicycle decals are available at no charge.

17. 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 Shipping Option Pre-paid Duty to European Countries.

18. Can I get Light Bicycle products from local shops?

We have ship our products directly to the consumer from China, USA, Canada, and Europe. Our products are also sold through some local bike shops, you can contact us and let know where you are located for a recommendation.

19. What can I do if I receive a damaged parcel?

Hi there, Do you sell spokes with a rim purchase like the NA shop? I'm planning on buying 2 rims to build myself. The NA shop offers Cx-Rays for 3.15ea with a wheel/rim purchase. Would you match that?

LightBicycle 2018/12/06

Hi Kyle, Yes, you can purchase rims and spokes only from us. I send you the quotation accordingly to your email. Please check. Do you like mtb or road rims? Which model do you like? Thanks, Lightbicycle

Is it possible to have a custom build with white spokes ?

LightBicycle 2018/11/09

Hi Marvin, Sorry,only blakc spokes are available. It is hard to order white spokes in small quantity. So, we order all spokes in black color. Because they have MOQ requirement for each spoke length. Sorry for the inconvenience. Thanks, Lightbicycle

Claudio 2018/10/26

Hi, I'm thinking of building my own wheelset for my bicycle for next year, for which I am considering purchasing rims from you. I have two questions: - I'd plan to run tubeless tyres on that wheelset, and some of your rims do say 'tubeless compatible'. Do you have feedback from people actually using tubeless tyres on them? How well does that work, and do you have any specific suggestions in terms of which tubeless tyres would work best for your rims? - My bicycle is fixed gear, i.e. I'll need to purchase the right kind of (track) hubs from somewhere else (I think you don't offer wheels built on track hubs, as far as I could tell). That should not be a problem, correct? Thank you very much! Regards Claudio

LightBicycle 2018/11/01

Hi Claudio, 1. Yes, a lot of our customers are running tubeless tires, so far we haven't received any feedback on failures. But not very specific about which brands works the best. 2. We do have track hubs actually, DT Swiss 350 and Novatec brand. Are you interested? Some customers building track wheels from us and truns out to be amzing. Do you have the ideal rims in mind yet? Which rims? In what width and depth? Thanks, Lightbicycle

Hani 2018/10/25

What brake pads (Make and model) would you recommend for your 55mm deep profile road rims to achieve the best braking performance

LightBicycle 2018/10/25

Hi Hani, The brake pads model would depend on the caliper you use. We do have brake pads available online. It's for Shimano Dura-Ace caliper. If you like other brands like SwissStop, it is okay, just please sure that you have pads that for carbon fiber rims only, not the ones for alloy rims. Thanks, Lightbicycle

Errol 2018/10/21

I see you sell a set of wheels with asymmetrical rims in 750B - AM 730 does that use the 2HD-RM650C05 rims so my question is are the 2HD-RM650C05 rims asymmetrical using these RM650C05 rims with DT Swiss 350 hubs what is the length of the spokes ? front and back wheels Regards - Errol Perling

LightBicycle 2018/10/23

Hi Errol, Below is the comparison for RM650BC05 (RECON series) and AM930 (RECON PRO series) 1. Rim profile, those two model rims are with slight differences dimension. But the biggest difference is 650BC05 with the symmetric profile, AM730, however, is 2mm offset asymmetric profile. RM650BC05 is with 30mm inner/35mm outer width, 25.5mm depth. RM650BC05 is with 30mm inner/36mm outer width, 25mm depth. 2. Technically speaking, AM730 belong to our new series RECON PRO, the new scratch proof tech was applied. How many spokes will you use on the wheels? Then we can get the spoke length for your reference. Thanks, Lightbicycle
