A buddy of mine had one in high school around 73 or 74. A white #172 model if I recall.I had a Raleigh Super Course and his was the first bike I rode that had tubulars.The bike seemed to disappear underneath me. Totally different ride then my bike. After that my Super Course seemed like a Varsity. Mostly attributed to the wheels. He had the metal Simplex Prestige rear dr. Mafac Racer brakes, Nisi rims and a Unicinitor (?) saddle.
