A mate popped round the other weekend and changed both tyres for me all he had was a couple of tyre levers. while he started on the beads I turned the compressor on and started sorting out airlines. Perfect moment for the motor to pack up then.. My mate was not phased by this and went and got a stirrup type bicycle pump from his car that has a little tank you pump up for seating tubeless tyres. No chance I thought, but it seated the beads first try on both wheels. Never seen the like of it.
My dad, and both older brothers used to be tyre fitters, they could fit a tyre on anything you want, 'cos that was their thing.
Same as any profession, right tools, knowledge and experience goes a long way.
Or, you can attempt things yourself, fuck up the rims, have air leaks and generally get things wrong.
If it ain't your thing, let the pro's deal with it.
Not like it's an expensive thing, and for the speeds these bikes do it's just the right choice.
