Hi,
Just to let you know that I read the saddle section, realigned the saddle on the new bike so that it tilted forward a little and went for a short spin with minimal discomfort. No special clothing - the distances I think that I'm likely to cover at this stage probably don't require it but i wouldn't have gone out at all if it hadn't been for accessing advice from this forum.
Tomorrow is another day!
Thanks, guys!
