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

At about 29:30 into this video, Sean Yates mentions Litespeed made Caloi titanium road frames

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.

I bet 99.9% of bike frames are made of a single 'metal'. Mixed construction frames are vanishingly rare in the real world.

Unless you mean the classic 80's marketing special where 'cro-mo' only refer to the tube with the sticker on and it's hi-ten from snout to tail. There's plenty of those.

Well given a lot of examples talked about in retrobike circles as the modern end are in the 80s/early nineties generation - there were some serious liberties taken when describing the purity of materials and equally even some hi-ten steel pipe built frames were taking liberties in their claims.

I’ve seen so called hi-ten steel frames that were built out of pipes that be rejected by plumbers (back in the days of iron/steel pipe plumbing) so poor grade they were.
