I feel like the increase in wheel width may have had the biggest effect on the tyre shift. It was hard to buy a road wheel that wasn't a 15mm bead width a few years ago, and it is becoming difficult to buy wheels that are not >20mm now. I can realistically choose a 28-622 and run it at 5bar today, that wasn't an option a few years ago. In fact, five years ago my everyday bike didn't even have frame clearance for a 25-622.

There is a different argument to be had if the point is "don't buy frames with road/tri geometry".

I guess my point is: some of us aren't just choosing shiniest shiny, we're choosing an option from the list that only includes shiny.
