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.

What you have is a nice looking old bike. I'd clean it up, get it ride-able then see if it was worth it to me to keep going on with a good rebuild.

Also, if you haven't already, post this in the classics and vintage forum. Some of those guys can probably tell you exactly what you have.

Thanks for the reply man. To the vintage forum i go.

You've got a nice Bridgestone...Japanese manufactured, well regarded. I picked up an RB-1 for a song myself just last year and really like it.
