This was a curbside discovery, a really nice older Trek. It's a little small for me (probably a 56 or 54cm) but is in good shape. So, I'm going to clean and tune it and get it ready to sell. I'm, however, having a hard time identifying it. Based on a serial number search it indicates that it's a 22", 1981 Trek 610. Unless the sizing is way off, it's certainly not in the 22" range. Also, I'm pretty sure that it came with downtube shifters as opposed to the upgraded SRX brifters that are on it now. In addition, it's a 7 speed/triple (170mm Sugino cranks), Dia Compe road brakes, has a chain hanger and only has braze ons for one bottle (on the down tube). Based on its potential value I may try to do a complete restoration before selling, we'll see. Any help with an ID would be appreciated.
