Bicycle frame serial number registry
Roberts frames were apparently sequentially numbered until 1984-85, when a new system began, with the
first two numbers represent the year, followed by the month and number of production within the month.

Placed in ascending serial number order.      Updated 5.5.2021

27 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, I’m still riding it! 84114 1984
