I need help finding out what year is my Trek 1400 and what size the frame is. I ready to sell it, I would like to find those out to sell it accordingly. I know it is somewhere from the late 80s or early 90s. The Frame is Epoxy Bonded Aluminum Made in the USA. The serial number is 476933. I have looked on vintage-trek.com which is how i realized it is either a 89 or 90. I just need help to narrow down the year and how to measure the size on the year of trek. Finally I paid $400 for this bike summer of 09. It came with Look clipless pedals and Shoes for them that were used once or twice by the previous owner and never by me, so basically new. I was thinking about selling it for $300, Bike, pedals and, shoes. Is that a good price or should it be higher or will there be no buyer for it at 300
