My French made 1976 Motobecane Grand Touring. I pulled it down from ceiling hooks that had held it since 1982 and replaced all the consumables and started riding it in Feb 2018. After about 400 miles, I did a complete tear down to the frame, rebuilt the French threaded bottom bracket with a new spindle and bearings, disassembled and cleaned the derailleurs and brakes, and put new cables and cable clamps on. I reinstalled the original saddle after I brought the leather back to life. Here it is on it's first 20 mile shakedown ride yesterday...
