Have you got a fat arse?

@hippy Doesn't look like a saddle for the wider-hipped cyclist though. winces
You're such a keen cyclist, come on - you must have measured your sit-bones to the millimetre, surely. Wossya numbers..?

Nup. Well at least not in my current memory range. I've always just tried saddles out.
Ebay made this easier over here since I could buy one, ride it and then sell it on again if I didn't like it for 1/3 the cost of buying new.
