Frame id needed.. painted over Titanium? Team USA. Nice!

Can’t help with id of it’s type - but don’t be surprised to find multiple metals - pure one metal frames are few and far between. Often they aren’t found on factory bikes unless they’ve sourced a wholesale supply of specialist build frames built to an OEM spec.

Where you do get factory built cycles with pure build frames, it’s usually the first series (usually short production) using hi grade specialist sourced frames, later production/series use reduced cost less pure single metal frames.

But there are often mixed sections especially around join sections that aren’t one metal due to rigidity/resilience workaround choices.

Try actually designing, and doing the obligatory FEA simulation runs to determine the rigidity and actual stress factors, and you rapidly understand why sometimes the end result of a production frame is less than as pure as the concept.

Believe or not, just building or designing based on theory or baseline designs can equally create an unfit for purpose design even if it’s technically (by theory) bombproof strong.

Just thought it was worth mentioning since the dark magic and sorcery of construction rarely gets mentioned.

yeah....those mass produced aluminium frames from Asia are really few and far between. Same for all those mass produced gas-pipe frames unless you mean the filler material for brazing being the mixed metal joint.

I don't want to argue with you, because it would be unfair, but construction is actually a science and not magic or sorcery.

And I'm a fan of mixed metal. LA Glam, Scandinavian death metal, thrash, NWOBHM... all part of life's rich tapestry.
 
The reference to dark magic and sorcery was polite reference to how people treat the invisible complexity that actually goes into the design and engineering of anything that’s not a matter of assembling in the right order and tightening up a few dozen nuts/fasteners out of an idiot-proofed kit of parts.

Clearly anyone with their head screwed on, brain engaged, and actually prepared to try to demystify the stuff that’s actually involved realises it’s anything but dark magic and sorcery. Mind you, half of those probably still pull the escape ripcord when the going gets tough.

Kind of ironic that the former SU was the biggest quantity source of Ti, where a lot of the Ti used on the SR-71 got back door sourced from, yet products utilising Ti in part or whole are rare sights from that part of the world.

I actually owned a military spec SU sourced camera (SLR) that has a full Ti frame and casing - it made most cameras look like toys in construction quality terms. As far as I know, it’s still being used by who I sold it onto.
