Finally got my 45mm wheels from Light-Bicycle just a few minutes ago, finally. They are beautiful. Very nice finish and everything looks to be top notch at this point. It was very nicely packaged. I will get a weight on them in a few days as I have to run over to my teammates house to use the digital scale.

Give me a week or so to get everything built up and I will get back to you fellas on how they ride.

Now I'm hoping the Hutchinson Galactik Tubeless tires mount up smoothly or I'm out $100 and have to go back to clincher.

Finally!!!!

I recieved the wheels today and took them for a 60 km test ride in mixed conditions.

They feel absolutely great - at first i was thinking that they were better than my zipp 404 fc tubular but i will have to do some more training on them and then switch to the 404s again.

I weighed the wheels on a luggage weight (not very accurate) and i came to the conclusion that they are about 1470 g for the naked wheels without rim tape, skewers etc.

I put on a set of GP4000 and some micheling latex tubes and my bike gained about 400 g which i find strange as the 404 FC are not that light. Are GP4000 a heavy tire??

Anyway questions are more than welcome - i paid tax etc. when they arrived but i still think they are great wheels and i would say they ride as a wheel twice as expensive.

I have previously ridden:
- Mavic Cosmic Carbone
- Zipp 404/808 Clincher (pre carbon clincher) (sold)
- Zipp 808 tubular (pre firecrest)
- Zipp 404 Tubular (pre firecrest) (sold)
- Zipp 202 tubular (pre firecrest) (sold)
- Zipp 404 Firecrest tubular

GP4000S are about 205g and tubes are anywhere from 60-90gms typically each. Really depends on the tubes. I don't run tape, veloplugs, way light and perform fine.

I know :)

Zipp 404 FC tubular - 1.380 g
CCC - 1.470 g

Weight gain 90 g approx.

The tubulars tires weigh around 250-275g each

Continental GP4000 - 210 g each
Michelin latex tube - 75 g approx

So maybe a worst case 2 * 50 g = 100 g weight gain

So where did the rest come from ??? Skewers will try and change them tomorrow and weigh again.

However the wheels are still great :)

EDIT: forgot the rim tape - no idea of the weight??? - will veloplugs save weight??

i will post a bunch of pics for you guys soon. give me a break i been busy lol.

the profile is crazy close to the Zipp 303 FC Clincher. I went to a bike shop that had some on display and compared in person right next to the Zipps and its almost identical. The LB 45 might be ever so slightly thinner, like 1-2 mm.

Where do you live that you had to pay tax?

How much did that run you for and how long did it take for them to build/ship it? Also, what's the complete spec's build? Those hubs seriously looks like BHS' UL66 and UL190.

The hubs are probably the same hubs. Bitex is a source of hubs for many. My total was 660 shipped to the US. I am a little disappointed that these were not like farsports with the basalt braking surface but I'll see how they stop. I'm in a flat area so not much brake use other than the sudden abrupt stops.

I'm highly interested in Light-Bicycle's U-Shaped 45MM. How's everyone's wheel riding so far? Also, what's Light-Bicycle's rim and wheel quality like in general?
