Hope that it'll be possible, I'm already working on that and will see what will be the best.. I have more options - to get the tubes here, maybe even from ENVE etc., or at last I can also order some metal moulds and make all the stuff by myself. That would be the way that I would like the most, to make it completely by myself
it would take some more time etc.,..will see what will be the best..
Otherwise I have some news from the PT4 project.
I made new seatstays, this time even 2mm thinner - you can see the wider side of the tube:
And also experimented a bit with the headtube. I made an experimental headtube with the groove for the drop-in bearing, and it turned out great! It's moulded in the headtube tube.
Here is the headtube that I'll use for the frame. You can see that it's for tapered fork:
I already posted the models/moulds for the bearing groove. Here just to show you how I'll use it:
And the resoult on an experimental headtube - pretty much perfec! And less than 4g of extra weight with the moulded groove:
I'm already thinking that maybe I'll go for the most WW option, without the internal routing. This year I'll experiment even more with those projects, and it will be a prototype frame that I'll really use for everyday ride.. I already laminated a new downtube without the integrated cable-stops and this time it's perfect. Will make also the toptube like that,..it's also better if I make it without the internal routing for the structure, altough the internal routing is very clean looking and nice,..but, I'll use it as a part of the development, and my aim is to make the best light and stiff frame. And if I really want to make it light, then it's lighter without the internal routing,..anyway, will think about that..but I'll make this frame a bit stiffer than PT3, that it will be a really stiff frame like I want to have it. The PT3 is already quite stiff, but I really prefer to have a super stiff frame, and will for sure experiment with some even lighter frames with different layup etc. later this year.
