Nice colours! Now I am jeaolous u guys have such nice colours and I went to a "conservative" one.

Do Western branded frames also Flex when they're considered lightweight?

" To be light or not to be light "; That is the question

Little update, received pictures of the paint job of my frame. Sadly it apparently will take another 30 days until it arrives. But im happy how it turned out. Bought a gold KMC chain and brown leather bartape to go with it. Now i need to find a brown sadle to match it.

You will drive at more than 40km/h with this frame without any problem and maintain this speed. Concerning the wall, I confirm the thinness under the pressure of the hand. It reminds me of my Hyper wheels (Winspace), very thin too.

While I don't really understand the squared design of the downtube, I can not imagine that an average rider would feel any difference. Especially because I guess the front wheel will make the bigger difference in that area and It should kinda shield parts of the downtube from the air flow.

I think the rider position, clothing, ... will make the biggest difference in aerodynamics.

we know for a fact that rider & clothing matter more than the bike itself, it's about 80% rider and 20% bike, afaik.
That being said, a bus shaped tube is a bus shaped tube. Even without a wind tunnel, we know that tear drop / kamm tail shaped things are more aero than round things, or boxes... And we know that buses aren't aero. You wont find an aero frame with a wide, boxy shape like that, nor will you find a frame that touts its aero prowess with a boxy shape like that - until proven otherwise, ofc. Given it's an ultra light frame, and making frames of that weight at this price point is a new phenomenon, and that LC doesn't make any aero claims, i think it's safe to assume it's not aero. Whether it matters or not is subjective. But even if it "only" costs 5W at 45kmh, i try to spend my money diligently, and given how incredibly hard it is for me to raise my ftp by 5W, if i'm going to buy a frame, and if i can, i'm going to avoid buying one that screams "i'm a bus". It's a guesstimate. It's also an aesthetics consideration, as i dont find that boxy shape appealing.

Absolutely agree with you. I am not an engineer, nor a specialist in aerodynamics. LC should send the frame to Hambini for review (ah! ah!)
