I'm really not trolling, or trying to cause a heated whatever... But why do you need to use a bead-breaker? Just plonk the wheel down on some soft ground, put your heel on the bead-wall, and let your body weight do it all?
Or am I the only one that is 100kg (+)? Been doing this since a kid though, and never a bead not broken.... Getting the damned bastard things to seat and pop correctly is a different story..!
Sorry to hijack, just really curious as I see this all the time and have never understood.
