[QUOTE=Seajay;664692]If anything was going to work it would be SKS Race Blades Long. Not to be confused with the original race blades.

Thanks very much for this suggestion and the photos - your interest is much appreciated. I've had a look on the Chain Reaction website and the rear one really looks as if it might have a bit less bulk where it goes between the wheel and the seat stays & rear brake fitting - which is where the main problem is with the Crud. I'll talk to the Specialized people when I go to the BS on Friday and see what they've got to say about them...
