All of those Bridgestone's shared the same frame geometry,---Grant Peterson was of the mindset that even beginning racers wanted a high-performance bike too

I I had one and pored over tons of magazine articles in those days trying to find something better in my price range

The bike was a bit heavy, but a lot of this was inexpensive wheels and generic hardware (seats, stem, post). --- the frame is also no lightweight, but was a true to life Norba geometry racebike at a price i could afford as a 17 year old twerp
