Hi, Jim,

I am submitting my girlfriend's bike to the current classic page. It's a 1984 Trek 620 that we found on eBay last November. It's dark grey in color. The frameset was designed for 27" wheel and the brakes I got for the bikes didn't work with the position of the cantilever bosses. I went over to Bernie Mikkelsen's at Alameda and had him move the bosses for me. Afterward, I sanded the areas around the bosses clean, steel-wooled it further, then clearcoated 3 times with satin transparent spray paint. It actually looks kind of interesting.

The frame has other quirks that I didn't anticipate. It has very little space for fenders, considering it's a touring bike. With 30mm tires there is around 5-7mm of space left. My girlfriend is very light and these tires will be fine. The distance between the dropout to the chainstay bridge and the seatstay brdige is are also different, so I use a wine bottle cork and ziptie to secure the rear fender to the chainstay bridge and make a better fender line. Megan is fond of old trek and really enjoys the bike. I walked her through most of the build-up process (at her request) so she can learn a little about bicycle assembly and repairs. Here is the build list.
