I think I have a 25mm tub on my zipp if you want to try it?

Cheers Indra. It might be a pain to arrange a try out though. I don't get a lot of free time to go cross city these days for such things. You reckon you could somehow measure tyre height when it's pumped up.

If I remember correctly. The 23mm clincher did chip some paint off the crown when it picked up bits of road debris. I might just settle for a 23mm tub.

Well I just measuered a fresh 25mm vittoria rally on a narrow rimmed ambrosio disc and it came out between 25.1 and 25.5mm from edge of rim to top of tyre at 130 PSI.

VS a 23c hardshell on a 23mm rim at 22.76 most of the way round at 75PSI.

Maybe this will give you some idea?
