Well when I originally purchased the bike I was told it was a Trek 614. When I looked at old brouchures all the bikes components were from the 613 model, Double crankset, Blueline components etc. So I have been calling it a 613, After finally looking at Vintage trek and matching the serial number it says that it is in fact a 1982 614. Basically I am confused of what bike I have now. Is there anyway the serial number got mixed up?
