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.

This claim would be dependent on the tubeset manufacturer. For the most uknown steel tubeset manufacturers this could be the case.

However, I would expect the big 3 - 4 (Reynolds, Columbus, Tange, True Temper) to only produce (in terms of metal mix) what they claim, the majority of which was CROMOLY.

Why would Columbus get in the trouble of producing a prioprietary / patended CROMO variant, the Nivacrom, that's made from Vanadium and Niobium, and claim this in their marketing, if the metals used for Nivacrom weren't Vanadium and Niobium and it was a stranard CROMOLY mix instead?

Not sure, I follow your logic here...just saying.

do you have more pictures of this frame? It would be interesting to see IBS's welds and work with titanium.

I have to do a microblading so the stickers are removed but I took the measurements.

Welds are looking pretty good!

I am not an a ti expert in any way but if the Ti alloy used is the same with Sandvik, Merlin and others then that's a pretty good frame I would say.

Well given a lot of examples talked about in retrobike circles aren't pieces of crap bike shaped objects sold in department stores, we'd all be keen to hear examples of those brands taking serious liberties taken when describing the purity of materials.

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.

Given how many people here lust over hi-ten steel frames (like... none of us) we'd really like you to back up these claims with some examples.

And remember, your claim was bikes being "mixed metal". What frames have you seen where cheap crap steel pipe has been subbed into place for Reynolds, Columbus, Tange, Dedacciai or True Temper.

We're all keen to know.
