I get alot of flack from most bike people who know me. I have a garage full of "enviable" bikes, but I do most of my riding on a 1985 Schwinn Sierra. These are the reasons:

1) The Schwinn is bullet proof and can carry anything I dare.

2). The Schwinn is super comfy, and I have changed the gearing to suit me, not whatever Giant/Schwinn thought was appropriate in 1984.

3). I am not that concerned that the Schwinn will still be parked where ever I leave it upon my return.

4). I do nto care if it snows, rains, or the planet is beseiged by Martian-cow-dung storm when I am on it...well, the latter may not be all that great.

5). A wise man once said: "If you have more than one bicycle, you always have one operational bicycle, and a bunch of others that need something fixed". I actually have two "operational" right now, but I have a bunch which need at least 20-minues worth of work.
