I should clarify, my post makes it sound like I just looked it up, but I did actually go out to the shed to measure! Always a slightly inexact science when they are on the bike but somewhere in the range of 685-690.
Cool, appreciate that, I think I got bumfuzzled at the bb height because the geo I was looking at (using as a template) was for 42mm not 48mm tyres, so my numbers are right, and having measured bb height on Winston 1 they are very similar, so it won't be a problem.
