Another cool thing about this bike is that the rear drop out is drilled for the Campagnolo Porta Catena system that was offered for a short time in the late 70's and very early 80's. (The system is NOT on this bike currently, could be added though) Here is a link that explains the system Porta Catena! It basically was an aluminum rail that was attached to the inside of the rear drive side drop out ( Camp 1010B) which was pre drilled and tapped. It was used with a five speed freewheel and the rail took the place of the sixth cog. The shifter was also different in that it had a special release which allowed you to shift the chain onto the rail so as to facilitate very easy removal of the rear wheel. Early French Randonneur bikes also had a similar, more integrated system sometimes brazed onto the frame by top constructeurs of the day like Herse and Singer.
The frame measurements are as follows:
- 54 1/2 CM seat tube
- 54 1/2 CM top tube
- 32 1/2" stand over height
