Like the above bike, my recent purchase appears to be in the mid evolution of the Centurion ProTour SN M8B01504, oddly it also has stamped on the bottom bracket in larger font size 072558 of unknown significance. Mine is the pearlized silver, with barcon shifters, triple crank (Sugino AT 46, 36, 26 which may not be stock). It too has the pin striping, and all chrome tubing. I will start another thread to detail the bike as found, but suffice it to say it has the "fat" C head badge, and chrome lugs to set it correctly in the 79 range even tho the sn suggests a 1978 build. It was at the evolutionary transition. and has been further upgraded by previous owners.

The chrome lugs are beautiful.


but why were the seat cluster lugs partially painted?

I have a 7 speed freewheel on Campy record hub so 126 spacing and a Suntour xcsport 7000 DR

I'm wondering whether the Sugino AT with low gearing 46, 36, 26 was OEM or a mod?
