This is the post I’ve been most looking forward to writing and also fearing with equal measure… Reynolds 753 was a tube set that took the bicycle world by storm. It had unrivaled strength while being ultra light and thin for a steel tube. It is probably the most mis-understood tube set and the one that has the most stories connected to it.

Creating an SBDU Date Timeline for TI-Raleigh Ilkeston Production

It is impossible to accurately date reference SBDU frames!

There it is, a simple fact. I should really leave this blog post now with that ‘bold’ statement. But that’s not like me, I like to investigate and I like to waffle…

I’ve wanted to write this post for a while, and I’ve tried to start and structure it a few times, but it has been difficult getting to grips with the scale of the subject. There was often either too much conflicting information or sometimes a complete lack of information about Reynolds tubes. Hopefully I’ve got a good grasp now, although it has still taken longer than expected to get all of this out of my head and crammed into a short, informative and hopefully coherent blog post.

SB Frame Number and Frame Detail Timeline – SBDU Ilkeston TI-Raleigh Specialist Bicycle Development Unit

My TI-Raleigh Specialist Bicycle Development Unit SBDU Ilkeston Frame Details

Frame details…, it is all about those little frame details… Frame details are hard to change. They are individual elements, fitted to tubes and formed into a frame when the torch melts the filler. Paint and decals are not the same, they can change over time, fooling you and misleading you with a different story… the frame detail should always tell the real story.

The SBDU at Ilkeston used a range of different frame and fork details over the life of the unit. The amount of different details they used means that this post may turn into an epic. I did consider splitting it into 2 smaller posts, pre and post 1980, but as this is ultimately a timeline post, I wanted it to be unbroken, and to start and complete in one go. Hopefully, it will be helpful for anyone doing research into their own SBDU frame. I’ll also try my best to fit dates and years in as I go. If you are a fan of the SBDU or simply need to know these details, then please stick with me. I learnt so much while researching and writing this post, hopefully I can pass this information on to whoever wants to read further!
