23mm Conti Supersonic. Or Conti TT. Maybe a Corsa CX if you must have 25mm. Or those Spesh Turbo Cottons come in 26mm.
Are these all compared on a Crr chart somewhere? Which roll fastest and can be delivered tomorrow? I don't ask for much do I? :)
My money would be on the Turbo Cottons rolling fastest. I'd be using one on the rear if there was an equivalent 20c gumwall that worked with the Hed3
