    No one sells a dedicated carbon touring frame, but you can get ones with suitable eyelets, and a few people do go touring on them. Carbon tandems also exist, demonstrating that it's strong enough.
    Please make sense when you post. No manufacture will make a 600g TI frame custom or not due to fact it would cost too much money. It's like I'm talking to a wall. Since you want to talk stupid, you go to a CF manufacture and tell them you want a complete touring bike made for heavy long distance touring. By the way, if CF was so great and so strong and so cheap to build touring people would embrace them like flies to schit.

    People spend tens of thousands on custom bikes. If that's not enough then it effectively can't be done. I'm sure new technology will come along to allow lighter Ti frames (like the 3D printing I linked to earlier), but similar advances in carbon tech will occur too, so it ends up with basic physics: carbon fibre has a higher strength-to-weight ratio, so you can build a lighter frame for a given strength.

    Like I said, people have toured on carbon frames. Touring bikes are almost all steel because it's tough (different from strength), which is desirable for touring, but not necessary for other road bikes. Also their riders tend to be more conservative than roadies, partly of necessity (it's harder to find a composite repair specialist than a welder when in the middle of nowhere). Even if carbon isn't an ideal material for it, it can be done, unlike building a Ti frame as light as carbon.

    By the way, since money is no object in this discussion, here is the lightest bike in the world currently: The world's lightest bike - BikeRadar The CF frame is 642.5 grams, but note the price. Anything can be done if the price is right.

    And what you said about steel being used on touring bikes is true, it is tough and it can be welded should by chance something happen. CF and TI would almost certainly have to be sent far away and the rider waiting for weeks perhaps to get it back, AL could be welded locally, I had a friend who broke his AL Cannondale touring bike, some local had the equipment to weld it back, but they had to reinforce the stays to the seat post with braces made of steel and then zipped tied and wrapped in duct tape, the bike survived till he got home and broke again on a leisurely ride at home. Not sure why the weld didn't hold up or why the braces had to be used, maybe due to the tricky place where the breaks occurred.

    Sorry to bump this thread, but anyone knows anything about this Carrera Scatto?
    I have a Carrera Nitro SL (carbon frame) and it is very confortable yet sufficiently stiff, but would like to switch to Titanium and I can get this frame at a nice price.
    About builders, I only can comment on my case, I have a 2013 Commenšal Skin Ti 26 MTB frame, welded at Ora Engineering Taiwan, and for me it is pretty amazing.
    The frame is fabulous, very stiff in the headtube and BB but confortable at the same time.
    Here is an "article" about Ora Eng. since they weld for Genesis also:
