Oh how I wish I can luck out on an RB-1, you sir are giving me false hope. I mean the bikes are literally being sold in the box unopened as a sort of raffle ish kind of sale. Seller doesnt know the specific model, he only knows that some boxes are mountainbikes and some are childrens bikes. Dont think these are 80's bikes, the boxes look pretty recent. He said he got them from a bikeshop that closed down for real cheap. I guess what im trying to find out is if anyone knows of a repository online for bridgestone where I can look up the lot no. or codes stamped on the boxes to determine what model is which before i buy.
