and the wheel/tire size is something easily dealt with when it's new tire and tube time? i'm somewhat "illiterate" on vintage bikes like this one ... i had an Austro Damier Vent Noir back when i was stationed in New Hampshire in the 70's and i'm restoring a Technium right now, so i know my way around the tool box and fixing my bikes, but things like thread sizes for a bike like this are out of my experience! just a few more questions if you don't mind.. the freewheel type and threading, the rear derailleur and bottom bracket threading. thank for your time!
