Unfortunately I don't know the bike serial number. It was purchased new by my mom in 1982. Please contact betsy_dot_pfeiffer_at_gmail_dot_com
1982 dark blue Trek road bike (model 614) with 27" wheels and a small frame. It has drop handlebars and shifters on the frame. The seat is slightly torn and says Avocet on it. It has non-original pedals, which can be clipped into or ridden with street shoes. It has a non-original black cargo rack with an obvious repair.
First 2 characters of serial number
