Bicycle frame serial number registry

Carl Fenske Summer of 1984, leading a group of students on a cycling trip in southern England. At the end of the trip, while in London, I left my group for a few hours to visit Roberts Cycling. I met with Chas Roberts where I explained that I wanted a custom-built frame suitable for bicycle touring.  I was measured and sized, and then Chas showed my several bottom brackets and frame lugs from which to choose; I also requested an extra water bottle mount and rear rack mounts and front and rear fork eyelets for fenders and panniers. The frame cost 225, plus 40 for shipping and customs. After 30 years, Im still riding it! 84114 1984
