SBDU Ilkeston Reynolds 753 Raleigh Pursuit Frame SH377T – Cleaned and Documented

SH377T SBDU Reynolds 753 Pursuit Track Frame Head Tube Detail

Every new addition gets a good clean and although it was already looking quite good, SH377T still needed a bit of work. Wet oil and grease on the surface of a tube will attract dirt and dust, and that is all that was covering this frame. When a frame is clean I can measure and document it. SH377T is a curious frame and I’ve looked forward to getting to this stage in my process.

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?

Finding bikes built by the Specialist Bicycle Development Unit (SBDU) that aren’t what they appear to be is part of the appeal of bike hunting and collecting for me. These are bikes and frames are hiding in plain sight, often with other builders frame transfers or paint schemes. They are flying under the radar, going unnoticed, and masking their real origins. SB8851 is a prime example. It is fitted with Dave Quinn transfers and came with a story that it was ordered from and built by Dave, but a closer look the at those frame features gave it away.

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?

I’ve not got much to write in this post as the pictures will hopefully say everything. This Raleigh Banana has been an awesome bike to build, a real blast from the past. I took it to the studio today to capture it looking its best…

SB7121 Reynolds 753T 1985 SBDU Ilkeston – Seeking Answers Under the Paint

Sometimes my frames come to me without any signs of originality meaning that I can’t accurately identify them. There is seldom a known history to accompany a 2nd hand frame. SB7121 was a classic example of this. I bought it on a whim, based on a basic description which indicated that it was probably a Reynolds 753 frame. The frame number dated it to 1985 and it had a hand painted finish with ‘Wheel Craft’ frame transfers, but underneath the paint, it was 100% an SBDU. I wrote an initial blog post on the frame but always wanted to come back and dig deeper and take a proper look into what it was.

Reynolds Tubing Wall Thickness Tube Gauge and Seat Pin Size

This post isn’t necessarily about the SBDU, but I thought I’d write it as I get asked regularly to confirm seat pin sizes, or to try and decipher what an SBDU frame might be made from based on the seat pin and tube size. After collecting several SB frames over the years, I’ve seen lots of different seat pin sizes used in Reynolds frames. I have seat pins ranging from 26.6 to 27.4 – and 753 frames with 4 different size pins. That demonstrates just how varied their tube gauges were. So here is a little post that lists some of the most common seat pin sizes and the associated Reynolds tube gauge (wall thickness).

To say that I’m happy with how 2017 has started is an understatement! My first SBDU bike for the year is built and it is stunning. My 753R Raleigh Banana is complete; and it has been such an enjoyable build to do. From getting the 753R SBDU frame looking its very best with new transfers, to working with probably the greatest group set ever made, Shimano Dura-Ace 7402, it has been a joy to work on this bike.

I’ve been collecting a few items for this build since getting my hands on the frame in December last year. It’s been a bit of a stretch as Christmas has drained funds, but I now think I’ve got all the components needed to get this built. I’m not putting myself through the ordeal of going for a period correct team build. Instead, I’m going for all the things that I love in bikes and bike components. This means I will actually come close to team spec, but retain some freedom to tailor the build for the parts that I like and the overall look that I prefer.

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.
