So i picked up this bike the other day free of charge. Ride mountain bikes ALOT and have built a few bikes in the past but when it comes to the roadie world i'm a bit of a noob. I tend to stick to rocks and dirt. So i'm curious as to what I have. Would like to clean it up and use as a means to supplement my conditioning for mountain biking. Obviously this is not a new bike, but is it worth cleaing/fixing up and using? Just from doing some searching on the interwebz it seems to be an 89 Bridgstone RB-1 but again, not 100% sure on that.
