Titanium lugs and carbon tubing available somewhere?

Framebuilders Thinking about a custom frame? Lugged vs Fillet Brazed. Different Frame materials? Newvex or Pacenti Lugs? why get a custom Road, Mountain, or Track Frame? Got a question about framebuilding? Lets discuss framebuilding at it's finest.

Titanium lugs and carbon tubing available somewhere?

Titanium or carbon lugs and carbon tubing available somewhere?

Hi,

Is there any place to buy titanium or carbon lugs for carbon tubing anywhere?
Would there be any possibility to make a carbon frame with titanium or carbon lugs yourself, something like this:

Thanks a lot for any input

those "lugs" are welded tubes. In effect, those bike are ti welded frames + carbon tubes

If you are going to the bother of making your own frame it is small step from mitering and tacking and then forming a lug from scratch versus buying pre-fab lugs of any sort.
It's also way more forgiving.

Hi,

yes, but it's ready built. Not DIY kit of lugs and tubing.
I ordered a Paduano racing Gladio. It is avaible in several versions. Mine is with carbon seat tube, down tube, top tube and full carbon fork (carbon steerer).
All lugs are made out of Titanium, so is the chainstays and chopsticks. You can use standard carbon tubes, or with inlays/stripes of PBO fiber (more elastic) or Boron fiber (stiffer).
I have ordered min with PBO in seat tube and Boron in down tube and top tube. For best possible comfort (rear triangle) but with best possible reactiveness in the front triangle. There is also a special headset you can order, which is made for Paduano.
The bike is customized for my length and style. Also, not to need any spacers.

OP probably lost interest. Again, those are Ti welded tubes with carbon tube inserts. No lugs

Yes they are tubes joined by welding that should still equal for being a lug. Or does it need to be brazed?
I know the reason why this sort of frame is done instead of using only carbon or only titanium.
I think it offers something a full carbon simply won't do.

I have no judgement about the construction method. This thread is about making such a frame, and the point is that if you want to avoid welding by buying lugs then this construction method does not do that.

There used to be carbon lugs, but the supply dried up. I've never seen a Ti lugged bike, only welded/bonded

an example of someone doing a Ti Lug CF tube Frame. http://www.bgcycles.com/customgallery.html

The Italian Company AlAn , offered a version of their all Aluminum 'Screwed and Glued' frames
with a Carbon tube Main Triangle.

You might be able to find some NOS aluminum lugs out there. I suspect there are sets of the carbon lugs too.

that was a show bike in the last few years. It's welded, he just ground down the welds. He also said it took him so long that he will never do it again.

The Constructeur thing is all about making stuff in your own shop when there is nothing readymade ..

Knowing what happens to Ti when TIG welded without purging Oxygen..
Imagine the Area 51 level of cost in making cast Titanium.

You can 3D print Ti with laser sintering.

How do you bond titanium? And how do you make it as strong as welding?
I had questions about how titanium is made stiffer to suit racing. I had some doubts going for titanium as some of these bikes is not as rigid. For me the curiousity of how they make different materials interact to best possible result, was perhaps the deal braker. Aswell as possibility to customize the bike to fit. I do believe it make some sense using both titanium grade 9 and customized carbon tubes (stiff and more elastic tubes) to get a balanced end result. Such as comfort and effiency to make a responsive bike not to heavy. It is also made to last. There is a constant flow on new carbon bikes and to some degree i feel many are not so different. I just felt to go kind of opposite way, look another direction. A blend of classic old school ideals and some new ideas.
