Oh do keep up!
I’m sure you could sell that concept to the triathletes, presuming it came in pretty colours.

I took my other tyre round to my friend this evening, taken it off the wheel and cleaned everything up first ( out of respect to someone who knows what they are doing).

He inspected it, put the tyre on and pumped it up first go, just like I did with the first tyre. I explained that I had spent 2 hours cursing it and getting nowhere.
He had the good grace to say “I would like to say it was skill, but it is just how it goes sometimes”. I still felt like a novice prat. Which I am of course.
