Thank you Jacek for all your efforts and help with our EM bikes !!!

It is all greatly appreciated.

I am still trying to figure out how to determine the year. You have confirmed mine is a 1990 and not a 1985 and I thank you.

W 5TTB and C 1649
I know it's a 55 and TSX Columbus tubing and made in the summer of 1990
This I learned from CM..Jacek !!!
And what, if any....is the difference between a Century .....and a Century Geo ??

Sorry to be a bother, but my curiosity and ocd mix is getting the better of me

Thank you again
