I have been chasing after a Bridgestone RB-1 for about 5 years without success. When I came across this 1991 RB-2, it was filthy, had 2 flat tires and a really cheesy padded seat. However, I was able to negotiate the seller way down and took a chance. I intended on converting it to a city back in some form other than a fixie. However, I got it home, cleaned it up, lubed it and slapped a B-17 saddle on it and fell in love. I replaced the white bar tape to get some color in what was a fairly boring looking bike, but didn't even have to replace the tubes. This bike shifts better than any bike I have ever ridden and still weighs under 25 lbs. with the Brooks saddle. It is also very nimble but still holds a line. I was really surprised at this. I figured the 700x28 tires would make it kind of sluggish.
This is now my primary ride. I have a 13-28t cassette on order only because I am old and out of shape. Now I am doubling my efforts to find an RB-1. N+1
