I've been enjoying this thread for a long time, and finally got around to figuring out how to post pics, so here goes:
My '89 Bridgestone MB-3. Won on Ebay for a little over $200.00. The previous owner probably never had it on dirt, as it was equipped with a high-rise stem and an oversized saddle. I Found the right stem at First Flight Bikes. Even the Ritchey tires are original and still in good shape. I love this bike! (P.S. pardon the trailer hitch on the seatposts of these first two bikes)
My '91 Bridgestone CB-0. My first "real" bike. I still use it as a fair-weather commuter.
My '94 Bridgestone MB-2. Won on Ebay (also) for a little over $200.00. Had to replace just a few things to bring it back to stock condition. The Mag 21 still works well. If I ever get around to racing, I think it would be a gas to do it on this bike.
