I have a Steve Bauer Boreas 12 speed road bike, it's all Shimano 105, I think it's a really nice bike (even though it's black and pink). Not sure who made them, but the frame is very similar to a Bianchi Paggio bike I have of similar vintage (mid to late 80's) that was made in Japan or Taiwan. I've seen a few Steve Bauer mountain bikes around here, too.
Lots of info on the web about Steve Bauer (the Fenwick Flash), Tour de France Competitor and Olympic medallist, he now runs a bike touring company that is very successful. website is at
www.stevebauer.com . I sent an email requesting bike history info, didn't get a response, but maybe the email didn't get through.
