Thanks- I did try one of these (my uncle's bike shed was a cornucopia of bike parts)- they do fit better but I would still have to chamge the brakes. The brake pads won't quite align with the braking surface and just scrape the tyre a tad. The brakes are the originals- Weinmann centerpulls and while a modern replacement would be more efficient, they are one of the few original parts left on the frame. I can ride it with 700's so will probably just carry on- it's fine for short rides around town, just won't ever be a bike I use for long rides ever again.
