Steve 2024/02/14

I'm 190 lbs. Looking to purchase AR46's w/DT Swiss 240 hubs and Pillar 1420 spokes. Plan to use these for road only. Can I use the 24 spoke options F&R or do I need to consider 28 spoke rear? thanks


LightBicycle 2024/02/14

Hi Steve, Thanks for your inquiry! For your weight 86Kg, it is okay to ride front 24H/rear 24H AR46+DT240 wheelset. It is durable enough for your riding. If you prefer much stiffer wheels and do not mind weight adding, it is also okay to go for front 24H rear 28H. Thanks, Lightbicycle

Hello Is a nipple washer important when assembling carbon rims? If it is, could it cause a problem?


LightBicycle 2023/01/23

Hi Király, ​Normally, we do not use nipple washers during wheelbuilding. Our carbon rims are durable enough. But you have to make sure the spoke tension is less than 130kgf during wheelbuilding. Which rims are you interested in? Moutain bike or road? Thanks, Lightbicycle

Hi! I want to buy Falor R35 rims, and I want them with special "paintless" finish, that PRO series has, which is how it comes out from a mold. There is "full custom" option in rim finish menu, should I chose it, and how could I describe that I need paintless PRO series-like finish?


LightBicycle 2022/01/12

Hi Peter, As you know, the paintless finish is because of the different m manufacturing and mold. The finish is not the only difference, but the strength, scratch resistance. So technically, we cannot make the R35 700C road bike rims paintless. Thanks, Lightbicycle

What type of carbon fiber are you using in your Falcon Pro rims


LightBicycle 2021/05/31

Hi Steve, The material we use custom Toray T700 and T800 prepreg carbon sheets with a custom resin system for the Falcon Pro series. They are thinner than standard carbon fibers, which allow us to form more laminates per layer, achieving stronger cross-linking reactions. And also maintain the lightweight feature. Thanks, Lightbicycle

Chris 2021/02/02

Hello! I am interested in the AR45 road wheelset - I am wondering whether I can still go for the Flyweight option or better stick to standard considering my total system weight: My body weight is about 75kg - adding another 10kg for the bike, bottles, clothing, helmet, etc. the total system weight is more around 85kg. While I understand that the official weight limit is 90kg on flat ground, I am wondering how much of a tolerance / contingency is in the 90kg and whether I am still OK to right coming close to the limit and also planning to ride mountains with fast decents on not ideal road conditions (potholes, etc). Thanks a lot! Best regards, Chris


LightBicycle 2021/02/02

Hi Chris, For your weight, it is okay to ride AR45 flyweight road disc wheelset. But standard version is more durable. Some customers are looking for lightweight wheelset. If weight is not very important for you, We recommend standard version expecially if you ride aggressively. Thanks, Lightbicycle

Andy 2020/08/16

Any recommendations for the following? Thanks! 1. What is your weight? 57 kg 2. What kind of riding and terrain you usually do? Any crosswinds? Hilly, big mountains, not much crosswinds 3. The tire width you plan to or currently use? 25c 4. Which matters the most for you? aerodynamics, stability, stiffness, and weight? Max wattage only 1100 watts - what stiffness would I require? Aerodynamics / weight equally important


LightBicycle 2020/08/19

Hi Andy, Is it your bike rim brake or disc? Then we can check which wheelset is better for you. Thanks, Lightbicycle

Tyler 2020/07/27

Hi there. I'm looking to upgrade my wheels for my Trek Domane SL7 road bike. I am a recreational rider but ride 100+ miles per week on semi-hilly terrain. I love climbing hills so I'm looking for more of an all-purpose wheel. I weigh 72 kg and live in NYC, which means that the roads can get pretty terrible with potholes. Some cross-wind at times. I currently ride 700c x 25 mm tires but am open to going wider. Any suggestions for what might work best for me?


LightBicycle 2020/07/28

Hi Tyler, I think our WR35 700C wheel would be a perfect match for your bike. The original wheelset of the bike is the Bontrager Aeolus Pro 3V TLR disc road wheel. The rims are with 25mm internal width, 32mm outer width, which is the same as our model WR35. You can check it out at https://www.lightbicycle.com/700C-32mm-wide-35mm-deep-carbon-road-disc-rim-clincher-New-Gen-Aero-Shape-tubeless-compatible.html. Thanks, Lightbicycle

Mark 2020/05/06

Hi, I'm looking to build some rim brake wheels but I'm not sure about the difference between the R45 and the AR46 rims. Which one is best for aerodynamics? I'm looking for the fastest wheelset with 25C wide tyres. Many thanks, Mark.


LightBicycle 2020/05/06

Hi Mark, Thanks for your inquiry! Normally, the wheel width as to be slightly wider than tire width to get better aerodynamics. But it also depends on the riding circumstance. Is there any side wind? Then we can check whether R45 or AR46 rims 700C are better for you. Thanks, Lightbicycle

Mike 2019/11/01

Hi, which rim do you advice considering I ride 28mm tyres (Continental gp4000 normally)? Internal 23 external 30 or internal 25 external 32? Thanks


LightBicycle 2019/11/02

Hi Mike, We haven't tested on GP 4000 tires yet, however, we did the test on GP5000 tires on our road rims. Here's the results for your ref. --Tire: Continental Gatorskin 700x28c --Pressure used when measuring width: 60psi --Results: 1. R series rims, R35/R46/R55/R65, 25mm wide, measured width 27.25mm, Relatively easy to install. No lever used 2. AR series rims, AR36/AR46, 28mm wide, measured width 28.64mm, Relatively easy to install. Lever used 3. WR series rims, WR38/WR50, 32mm wide, measured width 30.34mm, Relatively easy to install. No lever used Note that the above results and data are only applied to our road bike rims. Thanks, Lightbicycle

DONO 2020/01/25

Hi light bicycle, As your answer above, i have some confusion. On the 32mm rims width , why the tires width is less than rims width ? Is the 28c tires safely/recommended when installed on the 32mm internal width rims ? Thank You, Best regards, Dono


LightBicycle 2020/01/26

Hi Sir, Thanks for your reaching out!Some people use narrow wheelset to save weight. Normally, for 32mm outer/25mm inner rims, you can use 28C~50C tires. We have tried all  these width tyres and different width and different brands of tires on 32mm wide wheels 700C disc already.I can show you the tire fitting data when we are back to work. We are on Chinese New Year vacation from Jan 22th~ Feb 2nd. Thanks, Lightbicycle

Urban 2019/09/17

Hi I'm looking for rims to build a pair of wheels. they should be used for XC/XC Marathon. I'M thinking of XC925 and the Flyweight. Now my question. my weight is about 81kg + clothes/shoes and around 85 kg. Can I go for this rim or would you recommend Standard? Best Regards Urban


LightBicycle 2019/09/18

Hi Urban, Usually, we recommend using the flyweight on the front wheel, and the standard on the back for the best performance. The recommend rider weight for the flyweight version is under 90kg. But we don't usually recommend using it as the rear rim. But if you insist, you can use the flyweight as the rear rim. Make sure you don't do anything aggressive though on these flyweight XC wheels. Thanks, Lightbicycle

pascal 2019/08/26

Hello i'm just want to know if asymmetric rim U shape have the same avantage (equal ou less) with crosswind than the rim symmetric U shape ? Thanks


LightBicycle 2019/08/27

Hi Pascal, Normally, we do not recommend asymmetrical profile for road racing wheels. Asymmetric profile will affect aerodynamics. Thanks, Lightbicycle

Mats 2019/08/04

Can you help me with my wheel build? i dont now if my data in terms of dimension for hubs Novatec D411SB and D412SB are right for spoke offset right and left . I build up wheels with RM 29 C06 Flyweight 28H.


LightBicycle 2019/08/05

Hi Mats, For 29er XC bike rim RM29C06, it is symmetrical profile, not asymmetrical. So the left and right side of the rim is identical. Is it your Novatec D411SB and D412SB hubs straight pull or J-bend? Then we can get the spoke length accordingly for your reference. Thanks, Lightbicycle

Kamil 2019/07/15

Hello, I am 72kg and ride semi-competitively. I would be looking for a set of wheels for Gravel mainly. I'm looking at either the Falcon Pro 38 or 50 wheels. I'm just not sure if the 50 wheels have enough benefit for the weight penalty. Also, what should I choose for spoke count on straightpull DT240 hubs?


LightBicycle 2019/07/16

Hi Kamil, 1. Our lab testing results show that the rim depth has a greater impact on the vertical stiffness, so theoretically, the deeper a rim is, the stiffer it is vertically. If you are looking for something stiffer, you can go with the deeper rim WR50(32mm wide, 50mm deep) road disc bike rim. 2. If you are not ride anything aggressively, given your weight, you can get away with 24H/24H spokes for a gravel wheelset. DT Swiss 240s hubs are only available in 24H/28H for the straight pull, center lock feature. Thanks, Lightbicycle

Brian 2019/06/30

Hi There, I am looking into buying a set of Carbon wheels and was wondering what you could recommend. I weigh 268lb and would use them for road riding on semi hilly roads. Tire width would be 28mm. I am looking to reduce weight on my bike.


LightBicycle 2019/07/01

Hi Brian, 1. I got 2 recommended 700C road rims here for you to choose from. RR36C02 (28mm wide, 36mm deep, 410g+/-15), Falcon/standard series) and WR38 (32mm wide, 38mm deep, Falcon Pro series, 410g+/-15). You can check out the rim profile from the attachment. Also attaching with some actual wheelset photos for your ref in case you like to see them. All specs are customized optional. 2. Since you are looking for a lightweight wheelset, do you have an expected weight range? The most popular configuration is built with DT 350 hubs, which approximate weight would be 1594g+/-25. If you are looking for something lighter, we do have Carbon Ti, Extralite hubs available. They are more expensive but definitely lighter. 3. Since your weight is about 130kg, without gear? It's close to our rider weight of rims, I would suggest to customized a reinforced version of the rims for your build. It will add about 60g per rim because of the extra carbon fiber adding. Thanks, Lightbicycle
