I was in the LBS last evening & a guy walked in with this RB-2. He was hoping the LBS would want to buy it. I know nothing about these bikes but it just might be on the edge of "on-topic"? He (original owner) says it is a 1990 model. It has downtube shifters. Don't know if they were friction or not. Size is 59. All I can say is it looked to be in perfect condition. Naturally it is a lugged steel - skinny tubed bike. I did not have time to spend talking about the bike, but if anyone is interested I can put you in direct contact with this person as I took the time to get his e-mail address. Contact off-list?
