I have a 58cm French bike, less wheels, that you can have.
I would have to check standover, but maybe 'french fit'? HaHa.
Unfortunately, not as 'tuned' as a custom race bike.
Something maybe to try 650b, until you find a better way.
Follis brown.
Unflatering pic is all I got now. Ran 700cX33 with knobbies, so guessing 650b 38/40mm might work, but never done a conversion.
