I'm restoring a Moto mixte and the previous guy put in a 25.4mm post. It seems like slightly small because you have to completely close the gap in the seatpost slot to keep it from rotating. Yet, when I remove it and pry the gap open, I have to use what seems like too much force to insert a 25.6mm post. Btw, this was a heavily modified bike, with SA 3-speed IGH with 700c rims, single chainring, no FD, dual pivot brakes, a mtn bike seatpost, strange bars, mtn bike levers, etc. I've restored dozens of French bikes but have never seen one so far from stock. And the serial number is close to impossible to read. Makes it hard to date.
So, given all that, anyone know what diameter seatpost Moto used, in what appears to be an late 70's mixte? The new buyer wants a silver one and I'd hate to order the wrong thing and perpetuate the error.
