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

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

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

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

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

Jim 2019/06/17

What wheels would you recommend? Recreational/fitness riding only. Looking for durability, stability, decent shock absorption and long life. Speed is a secondary concern since I’m an admittedly slow rider and not getting any faster as I age. Currently ride mostly hills since I have two cat 2 climbs right next to where I live. Hope to run more flats in the future but most of my riding is 10-15 kph up and 40-60 kph back down. Weigh 84kg. Running Conti GP 4 season 700 x 28c. Might go to 32mm at some point. Roads are a mix of perfect new asphalt and rough/bumpy/awful chip seal with cattle guards along the way. High gusty crosswinds in the spring to contend with. I was thinking RR3602, 28 hole F&R w/ Sapim CX Ray.


LightBicycle 2019/06/18

Hi Jim, Thanks for your feedback! More shallow rim profiles are lighter and more stable in crosswinds. And deeper rim profiles are heavier and stiffer. RR36C02 road cyclocross wheelset is suitable for you. It is used for Road/CX/Gravel. Its profile is not too shallow and not too deep, which takes count of lateral stability and radial stiffness. Do you like Onyx hubs or DT Swiss road disc hubs? We can quote accordingly for you. Thanks, Lightbicycle

"we’ve created a simple Rim Depth Recommendation Form" - where can I find it?


LightBicycle 2019/06/11

Hi Andrzej, It's not available online currently, could you let me know what kind of bike rim carbon fiber are you looking for? I can make some recommendations according to your profile. A few questions first. 1. What is your weight? 2. What kind of riding and terrain you usually do? Any crosswinds? 3. The tire width you plan to or currently use? 4. Which matters the most for you? aerodynamics, stability, stiffness, and weight? Thanks, Lightbicycle

Fuad 2019/02/22

Hi, Are you guys planning on developing pro versions of road falcon rims?


LightBicycle 2019/02/23

Hi Fuad, Yes, we do have the plan to launch the Falcon Pro series. Currently, our engineers from the Falcon Program Team is trying to develop new technology on the road rims. It will be ready in 2 months. Thanks, Lightbicycle

Dustin 2019/04/11

Hello, Is there any update on this plan? The "two months" that you mention above is closing in quickly. Is there possibly a mailing list that I can opt in to for when the Pro is released, so that I can configure something up around that time? Thank you, Dustin.


LightBicycle 2019/04/12

Hi Dustin The new road rims will be available in May or late April. Thanks, Lightbicycle

Alan 2019/04/19

Do you have rim profiles available for the new rims and will there be disc and rim brake versions?


LightBicycle 2019/04/20

Hi Alan, Attaching with the rim profile of our new Falcon Pro series rim for your ref. Note that they are only available in disc version considering its wide profile. It is 32mm wide, it will be too wide for your brake caliper. If it is not wide for you, we can manufacture rim brake version for you. Thanks, Lightbicycle

Marek 2019/01/04

Hello, I am just wondering what kind of ratchet to pick for my XC925 wheelset - 18,36 or 54T. What are the differencies? And also I am not realy familiar with a straight pull spoke head. Would zou recommende it for me and explain it a little bit more. Thanks Marek


LightBicycle 2019/01/05

Hi Marek, The 36t or 54t provides a noticeable amount of extra engagement points which helps when ratcheting your freehub during slow speed technical situations. It will help the wheelset feel more responsive overall. The 18t is more reliable as the grooves are the deepest in the star ratchet, whereas the 54t has the shallowest grooves and the 36t is right in between those 2. If you put out a lot of torque and don't like messing with your equipment, stick with the 18t, but if you want more engagement the 36/54t offer a noticeable performance gain. For mountain bike wheel, J-bend is the most popular option as they are easier to work with and replacements are readily available. Straight pull spokes can be challenging to true because they rotate in the hub flanges as you turn the nipples. Some riders prefer the slight gain in stiffness of straight pull spokes for lower spoke count wheelsets . If you like lighter wheelset, you can go for straight pull mtb xc wheels. Thanks, Lightbicycle
