Another Centurion to help ID
 

Just got a Centurion with ZJ73055 stamped on the vertical tube, which goes up to the seatpost, located just above the bottom bracket.

Components (not sure which of these are original):
Suntour stem shifters & derailleur
SR crank
Diacompe brakes & levers
Sakae bars
Sansin front hub

Any help identifying this bike would be awesome!

This looks to be on the lower range of their lineup just judging by weight and Suntour parts. Maybe 73 means 1973?

Without pics or model names for the components this is a futile task but the laws of probability say it would likely be a boom era LeMans. Spend some time on the components page of the Vintage-Trek website to detemine the year of your components.

Cool. I will do some research on that page and will put up some more info w/ pics tomorrow.
