The prices I got quotet 1-2 weeks ago were:

660$ Frameset including seatpost, clamp and fork, (2 UDH, 1 mounted)
820$ Frameset + CGB02 Handlebar with Spacers
+8$ per extra UDH
+26$ per R+F axle
+15$ per headset
+195$ shipping to EU (265$ if you get 2 frames, no tax/duties on top)
+265$ paintjob

+4.5% PayPall fee

I'm using SLS Nylon PA12.  In case you want to be really secure for headset spacer, you could make them purely cosmetic by using a normal round spacer and using the outer diameter of that one as inner diameter of your custom spacer. Not that I've done that, because I'm confident its structurally sufficient for its purpose.

Thanks. Taking round spacers and printing a cosmetic cover sounds interesting. Will check it out when I get the frame.

I requested clearcoat with the top being translucent blue fading into the raw carbon. It's light and still adds a special element to it. The attached video gives a better representation than the picture

I do like the fade and the overall look of it, expecially the translucent blue/carbon part. It's not my cup of tea though, I guess mainly because I don't find the clearcoated carbonfiber look very appealing in glossy. But that's totally subjective. It looks incredibly well done.

Does anyone know how good Carbonda's paintjobs are and if they do somewhat complicated jobs? I am usually relatively picky with such things and I would rather go with their unpainted black version than getting something that I don't like in the end. On top of that I did find a couple of posts reporting that the paint chipped easily in certain places. The paintjob would be based on the Cube Nuroad C:62 SLT Design (see image ). I wrote to their salesteam but didnt get an answer yet.

How many spacers are you running now with your current bike? If you are already slammed and with a -17deg stem, I would say go for a size smaller. If you have some spacers below with a -6deg stem, the XL will be fine.
As an 505SL owner (in XL), I can say this is really a top tier frame where a lot of big brand's gravel bike cannot compete with. It has the modern features like T47BB and UDH, the ride quality is like a road bike with sharp cornering, it's stiff yet very lightweight (mine was 1050gr for XL), and I've been able to put 45mm schwable G-One RS in it without any scratching damage in muddy conditions.  I can imagine if you combine this with LB's wheels it's gonna be a fast machine. Almost a kill for a commuter bike.

Thanks for your input. It isn't meant as a commuter, thats what my Rose is for. This is for regular workouts and trips, where I - until now - used my Rose too. I guess I will go with an XL frame then. Did you order/use the Carbonda axles/headset, are they any good?

Going for an integrated cockpit on a new bike is always a gamble concerning the fit. Compared to the big brands, the investment is not that big, but still it can be a waste of money if the fit is not right. You could always buy a different one afterwards. There are plenty of options on aliexpress around 150EUR.

I guess I will take the gamble on the Carbonda Handlebars then.

Bike parts list: You could have a look at the Rival shifterset rather than the Force. Personally I prefer the fit of the Rival shifters (less bulky) and they are cheaper while having the same weight.  Also since you are running 1X, you might want to opt for the Xplorer deraileur in case you want to do more intensive gravel. But that's depending on your riding terrain.

Yeah I'll def. have a deeper dive into that on the weekend I am jumping back and force between the xplr/non-xplr and rival/ force and compatible cassettes.

505 SL does seem like the right frame for that tire choice, I assume you're going for an "all-road" type bike?  Road tire size with a bit of knob for off-road, but not off-road enough to need a true gravel tire?  Do you ever see yourself wanting a full width gravel tire in the 40-50mm range, which would then push you to a true gravel bike, like a CFR707?

The goal is to get an Road/Light Gravel Bike. I dont intend to use it for anything more than relatively flat, light gravel roads for now. Allthough I thought if I add a 2nd pair of wheels with ~40mm tires and a 10-44 cassette I could do some (lighter) gravel trails with it too. Which is why I am currently indecisive about the groupset.

Which sparks the question, do you want it to feel the same?  You say you want more sportiv, do you want a more aero position, so lower stack?

Currently I am sitting very upright on my Rose, which I want to change to a more aero Position, but I dont want to go crazy so that frame seemed like a good compromise. The decision is more or less only based on the evaluation @bikeinsights saying that the Rose frame has "Average stack and reach" and the Carbonda has a "Somewhat aggressive stack and reach". But if I go to the Carbonda in L the reach stays nearly the same but the stack of the Carbonda is 15mm shorter. Hence the question, which frame size is better for my goal.

2. I chose the integrated handlebar with my CFR707, but I'm switching to a separate bar/stem.  You can mostly hide the cables with an FSA/ACR stem, or heavier knock-off version on Aliexpress.  I want to dial in my fit with a handlebar narrower than I could find in integrated, so that drives a separate bar/stem.  Plus integrated bars have handlebar angle fixed.  If it works for you, then the integrated bar is awesome.  But if it doesn't, there's nothing you can do about it.

I think I will go with the Carbonda handlebar for now, as you said I could change it later on and I don't think I will get a better deal for a handlebar and stem.
