french threaded bolts?
I got some new shifters for the Cilo I'm working on, but I'm having trouble installing them. None of the (presumably Metric) bolts I have thread into the shifter bosses properly. I remember hearing a while ago that some Cilos were french threaded...I didn't realize this applied right down to the shifter bosses. Does anyone know if there is a French-specific bolt threading, and if there is, where I can find bolts of this specification?

I think Simplex had a some different threadings, if that helps you search for it.
Or you can retap them

Steel or aluminum Cilo?? If it's aluminum, it's really a re-branded Vitus 979 frame and I believe that they are mostly, if not all English treaded, so you will not need any French treaded stuff on the bike.
I'm sure my Vitus Carbone has exactly the same threading as the 979 at the shifter bosses and the bike originally came to me wearing Shimano DA 7400 click/friction shifters which I'm sure are not "French" threaded in any way. In fact, regular water bottle bolts (M5s) can screw into the shifter bosses.
