I re purposed my 1987 Schwinn Sierra into a commuter bike. I bought this bike new in 1988. It was loaned to a friend in VA for a while. I had him bring it to me about 10 years ago. I finally got around to setting it up for commuting and touring last summer. A few recent adjustments and the discovery of this forum calls for a picture post:

I added a speedometer, fenders, Panaracer 1.5 tires, rear light, and some touch up paint.
I had some 1.25 tires on there last year, but they were mixed and one was starting to dry rot. These will probably not be as quick, but on the ride in today I noted the are more comfortable.
