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?

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.

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

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

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 years with an upgrade option to lifetime warranty!

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?

If you’re used to calculating your own spoke length using an online calculator, you can reference our ERD measurement on our website. Please note that our ERD measurement doesn’t add in the nipple head dimension. So if you’re using standard nipples, the ERD listed should work in most calculators and consider that the shortest length to go with (round up to nearest mm). For nipples with raised heads like DT Swiss Squorx nipples or double square, you can add 2-3mm to the ERD measurement.

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

If you’re not very familiar with calculating spoke lengths, please contact us if you want us to calculate tit for you. 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
Fatbike wheelset 100-110kg/f 100-110kg/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, 65 USD roughly is added for this service. 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 Shipping Option Pre-paid Duty to European Countries.

What can I do if I receive a damaged parcel?

You need to inspect the product carefully before accepting and signing for it.

Hello Fellows, I trust you are well. I have a set of boost DT Swiss hubs and Aerolyte spokes purchased to length to install a set of your AM 930 rims onto. I now realise I will possibly be using higher than 35 psi ( rated ) tyre pressures. OOPS. I am wondering if you have "lipped", higher tyre pressure rims, so as I might be able to use the spokes ( a bit pricey, here in Australia ), I have. These are to be gravel, tourer bike wheels. Which is why I chose the 30mm robust rim in the first place. I have a set of the AM 930 ( heavier duty version ), on my MTB. They have been excellent. Thanks for any information you may be able to provide. Kind regards, Michael.


LightBicycle 2019/01/21

Hi Michael, It is great to hear that you like our AM930mm 29er rims. May i know what tire pressure are you going to use? For hookless, in our lab test, it is okay to ride if you ride around 60psi. Also, may i know your tire width? Then we can check accordingly for you. Thanks, Lightbicycle

Hey, I have a Liteville frame with a EVO6 standard for the rear wheel. Can I order a rear wheel with a boost hub but built symmetrically according to the EVO6 standard?


LightBicycle 2019/01/15

Hi Thorten, We did some research on the EV06 standard technology, and found that its very similar to the Cannondale AI system. We have built a few sets wheelset with the 6mm offset for the Cannondale AI system. So, we can build wheelset for your EVO6 bike. Which wheelset are you interested in? Thanks, Lightbicycle

hi, i'm building a set of your 55mm deep carbon 700c 25mm U shaped clincher rims 20 zero cross front and 24 two cross rear for a customer. The erd lists as 530mm "not including nipple head dimension". I'm using sapim polyax aluminum nipples. Does using these nipples add to the erd for spoke length calculation? Do you suggest using washers on the spoke nipples for these rims? Thank you. -Robin Robin's Wrench Maynard, MA, USA


LightBicycle 2019/01/10

Hi Robin, We got your message here. We build wheelsets without washers here. So, it is okay to build wheelsets without washers for you, but make sure that the spoke tension is less than 135KGF whild building wheels. For rim ERD, it is caculated like this. I think below will be easier for you to understand it. Rim OD-2*rim depth+ 2*rim spoke hole wall thickness= 633- 2*55+2*3.5mm=530mm Please let us know if you have any other questions. It is our pleasure to help you. Thanks, Lightbicycle
