Raleigh Frame Numbers 1973 Onward. Worksop Carlton and Nottingham Lightweight Unit Frames, Specialist Bicycle Development Unit (SBDU) and Raleigh Special Products Division

This isn’t intended to be an Internet resource of Raleigh frame numbers! If you are reading this for anything other than SB number sequences from the SBDU then please make sure you corroborate my information with other resources.

This blog post covers a basic background of things I’ve learnt about Raleigh frame numbering systems during my own research over the last few years, from the introduction of ‘W’ numbers at TI-Raleigh’s Worksop Carlton factory in late 1973, extending through to the late 1990s and Raleigh’s Special Products Division. The only numbers I’m confident about are the Specialist Bicycle Development Unit (SBDU) SB frame numbers at Ilkeston. Some of this blog post, especially the late 80s / early 90s is what I will call ‘work in progress – thinking out loud – still formulating things in my head‘ type of work, there just aren’t enough bikes available at the moment to provide more accurate detail.

Specialist Bicycle Development Unit (SBDU) Frame Ends

The Specialist Bicycle Development Unit (SBDU) Details of Fork Ends and Dropouts

Having a large collection of SBDU frames means that I’ve accumulated most of the various features that they built with. Fork ends are one such area of the frame design where I have an almost complete set, ranging from the earliest 531 frames produced at Ilkeston using Campagnolo 1010/A, through to frames produced at Raleigh’s Special Products Division using their own ‘RALEIGH’ stamped ends.

I’ve always kept an eye out for anything interesting and different with an SB frame number, something that might expand my collection and add a new dimension, even if that means moving outside my comfort zone of the Specialist Bicycle Development Unit (SBDU) at Ilkeston. My initial interest, and basis of the collection and blog was always Ilkeston built frames, but this moved on when I got my first SBDU Nottingham frame, I now have 3 Nottingham built SB frames, SB8851, SB8868 and SB8945. Today things have moved on again with the arrival of SB9529.
