frenchies or whatever it's called on holloway road sell 7mm allen keys, if that's any help.
and yea, i had a cinelli stem with 7mm bolt. also, i had a bunch of different cinelli stems, all the same model but some which were rounded off, so was gonna just swap the bolt over but i had a bout three different bolt diameters so couldn't swap them over - another weird one.
