I too had a light blue Soma Sport that I purchased in 1979. This bike weighs in at about 26 pounds without the kickstand, reflectors, and replacing tires with lighter tubes and tread. Most people would not think this bike had much potential, but here are personal acomplishments that I had on this bike:
1983 - First Place finish in the Shippensburg University (Men's Stock).
1983 - Second Place finish in Westminster, Maryland (Men's Stock).
1983 - 80th place a the Dr. Pepper Classic (180+ riders) Average speed exceeded 25 miles per hour.
1984 - First Place finish in the Shippensburg University (Men's Stock).
1984 - 5th in the Pennsylvania State Championship race at Fort Letterkenny, PA (Men's Stock). Note other riders were making fun of my sport touring bike at the start of the race. I walked away with a trophy. Technically I blew this race in the last 400 meters.
1984 - Second Place finish in Westminster, Maryland (Men's Stock)
1984 - Second Place - Kapona Classic - Harrisburg, PA (Men's Stock)
1995 - 205 mile bike ride over eight mountains in Pennsylvania in a single day. Bike was modified slightly.
