I acquired a 1990 Bridgestone RB-1 last year in nearly-new condition. It even had the original Bridgestone tires on it. It also came with the stock RB-1 group for that year, which was Suntour GPX cranks, shifters, brakes, freewheel, and chain. Headset was a Hatta Vesta. Wheels were Sansin hubs laced to Wolber rims.
since then, I switched up the groupset to N.O.S. Shimano Sante, with Sante hubs and Mavic Open Pro rims. I kept the original Sugino seatpost, Suntour BB, and Nitto bars. The switch made a great bike into my favorite bike. I don't have any intention of changing the group again. Sante is so awesome!
So now I'm sitting on the original group set and I'm not sure if I should keep it or sell it off. It's all in good condition and I think I could get $200-300 for it. On the other hand, I was thinking that if I ever sold the RB-1, maybe a collector would value it more with all the original parts.
Opinions? Is it worth holding onto or selling? Does it matter that much to collectors? GPX is not exactly in demand these days.
Here's my B-Stone with the Sante group...
