Help! My new Ti 90's bike

[Fatboy1974]

Suposedly a Biketech proto. Im looking for info. Seems a Tig Titània from Japan. What do you think? (Small fisured on seatclamp) But seems controled with some idea from engineering teories. Syncros crankset seems to be not inside enough. Maybe may BB is ISO and crankset is JIS? Is It dangerous if Chainline is acceptable?
Black tires or tan wall ones? Ti stem or black stem? Thank you for your feedback!

That’s a lovely tasteful build

Nice

Is the tube set externally butted? I cant quite decide from the pictures, the top end of the seatstays makes me think yes but Im not sure about the headtube junction. Any chance of some close ups of the seat cluster, BB cluster and the head tube welds?

Any idea of manufacturer?

Looks like the Ti 6-4V made Emery.
Here’s a link of that

Looks like the bb axle is too long.
Ideally the middle ring ought to line up with the middle of the cassette sprockets or 1 either side.
You want to get that tear at the seat clamp lugs fixed - any decent titanium welder could sort this out () because it's nice and accessible.

You might want to unbuild the frame so you can post it to a pro.

Yes. But I will ride a little to check some details. I was unable to wait!
