Any question answered...

Got given one of those Espresso 43mm rear wheels, just tried to put a tyre on it and it seems that it's actually slightly smaller than 700c? Putting a wire bead Rando on is effortless and the bead starts to pop off once there's about 40psi in there. It's impossible to get the bead to seat properly all the way around the rim. Is is possible that it's significantly <622mm ERD?

Definitely not a 650c, before someone suggests that.

Don't let gaggles see you criticise the espresso wheels.
