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.

After selling one of my frames a few years ago (SB447), I promised myself that I wouldn’t sell another.

However, I had a frame that was a duplicate of another and so I took the opportunity when it came to swap it, with the intention of enhancing my collection.

The last time you saw this frame, it was dirty, greasy, dusty and covered in spider’s webs. The parts were rusty and some were even beyond help. But after a few days and some hard work and elbow grease, the frame for SB1861 is looking so much better; although it did give me a bit of a issue.

A Collection of Collections My Raleigh SBDU Collection Obsession

The time is 9PM on Thursday 15th December 2016 and my SBDU obsession has recently added the latest frame to my collection. The collection currently totals 17 SBDU frames and bikes. When I look at these frame and bikes it amazes me how many times I can break them down into different sub-categories, or smaller, more specific collections. So out of these 17 frames and bikes, what smaller collections do I have…
