I had to postpone my visit to Macclesfield for a brew with drystonepaul and to drop off the frame and forks for powder-coating by one day to allow him to redecorate his kitchen
and I'm glad I did as the tyres arrived - so I got the chance to make sure the tyres are actually going to fit!
I'd checked on the Schwalbe website and widest crusier tyre is 60mm which would give me just enough clearance if I'd measured correctly. But seeing as I'd had problems with the front wheel alignment (one of the fork drop-out is further out than the other when you look down the fork using the canti bosses as a guide) I was nervous. Having had trouble seating other Schwalbe tyres before, I just put enough air in to check the seating and the tyres are looking pretty fat. Seating corrected no problem then they took ages to blow up to full pressure (max 60lbs) at which point they are even bigger... gulp!
Anyway, they are tight but they fit - JUST - they're not as close as that as I've sorted the front wheel alignment now to give a whole extra ~1mm!
