SBDU Rarity – Can Adding Some Context Correct Common Perceptions

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

What would you consider rare about the Specialist Bicycle Development Unit (SBDU)? I’ve heard people say that SBDU Reynolds 753 frames are rare… are they, or is that just perception? Defining something as rare really has to be done carefully, and in relation to the context of the subject. The way things are perceived is not always the way things actually are.

The Mysterious Carlton Capella Lugged Early Ilkeston SBDU Imperial Tube Reynolds 753 Frames

In the beginning there was Metric Reynolds 753 tubing, and then later in 1982, a new Imperial Reynolds 753 tube was introduced. The new tube, called 753R, had different diameters, different gauges and was slightly heavier than the original Metric tube. And that’s how it was always known… Metric 753 before 1982 and Imperial 753 available after 1982. That seems quite straightforward doesn’t it?

One Step Closer to Finding That Elusive SBDU Ilkeston End Date

When did the Specialist Bicycle Development Unit (SBDU) at Ilkeston close and relocate to Nottingham? What frame number were they up to at that time? Those are just two of the many questions that surround this seemingly mysterious unit. I’ve been searching for the answer to these questions for as long as I’ve been researching the unit. Late last night, a friend sent me a link to an SBDU bike that may finally answer at least one or maybe both of those two questions.

Now that is a massively bold statement to make… here it is again just to make sure that I did actually say it… “The most comprehensive resource available for frames built at the Specialist Bicycle Development Unit (SBDU)…” 

The SBDU and Their Use of Reynolds 753 Reynolds 753R and Reynolds 753T

There has always been lots said on the subject of Reynolds 753, and that doesn’t surprise me. This tubing had such an impact on the sport of cycling; the frames and their riders were breaking records before anyone even knew 753 existed! 753 frames are still sought after 40+ years following their introduction. You can’t go a day without the subject of 753 cropping up on the internet and the online debates and discussions mean that there are always stories and different opinions. But are these stories real and are the opinions accurate? What is truth and what is myth? What are these stories? Have I done enough research and accumulated enough data to either prove or debunk them?

Searching for an End Date of TI-Raleigh Specialist Bicycle Development Unit (SBDU) at Ilkeston

** This post was updated in June 2017 and can be found at this link **

My attempt to define a date timeline for SBDU frame numbers was published in July 2016 and has so far stood up to the test. That blog post hopefully provides some substance and reasoning behind my opinions and shows why I think SB numbers fall into specific years. I wanted to add reasons and facts to back up my theory, I didn’t want to add another random list of numbers to the numerous internet lists that already exist. I found two important periods difficult to define, one of them was the end of the SBDU at Ilkeston. So have things changed since that post was published?

A 2016 Review of My SBDU and TI-Raleigh Ramblings. Thanks for an Amazing Year!

Where do I even start to describe how much of a great year 2016 was? And how on earth am I going to try and beat it in 2017? I remember I had exactly the same feelings at the end of 2015 – that year had seen me double my readership over the previous year. But 2016 has seen so much more! I’ve had record breaking days, record breaking weeks and record breaking months – so how am I ever going to live up to that! That is the dilemma facing me as I start the new year.

Showcasing My TI-Raleigh SBDU Bikes Through Images and Bike Photography

I don’t think my blog would be read by as many people if it wasn’t for the images that accompany each post. I might be in the studio with a full frame DSLR, back drops and lights, or in the workshop with just an iPhone and window light, but wherever I am, I try to cover everything I do with at least one image.

An Update on The TI-Raleigh Ilkeston SBDU H Reference Number

It’s been 18 months since I wrote a little about the ‘H’ reference number. This is the reference you sometimes see under the bottom bracket of an SBDU frame. Well since then, I’ve dug into the SBDU data, written a couple of timelines and become a bit more clued up on that ‘H’ letter.
