Bridgestone RB-1

This is a vintage road bike with downtube shifters. It was Made in Japan I believe in the 90s. It is primarily a white and dark green frame with two stripes of red and white - one on the seat tube part of the frame and the other on the down tube close to the fork. It has a faded number on the under side of the downtube but its hard to make out. Serial number recorded here was found on the bottom bracket.
