Bridgestone MB-1. I bought this new in 1991 or 1992 in Raleigh, NC. Original rims, but I've put on street tires as she's a blast on the street. Deore XT components, Taper-lite flat bar, SPDs. This is a very good example of Bridgestone awesomeness. I think I have the Bridgestone brochure and will try to dig that up for the purchaser . Everything works great, there's a small crack on the aluminum seat post (NOT the frame). Typical wear and tear, but I'd say it's in good-great shape.
