This is all very true, and you can build an excellent bike with physics but there is no guarantee that a bike with great numbers won't ride like a bag of shit. The numbers aren't always right when it comes how a bike feels when you ride it.
A close friend of mine was riding for a team run by a management company that imports custom made carbon bikes from France, as a race bike for last year, because they didn't make one already he asked them to copy the exact geometry and size of his Cannondale Flash 29er from the previous season. They copied it exactly, if you lined it up and measured it, it had all the same measurements. Yet his new bike rode like a shed, nothing like the original.
