If I ever get the time and opportunity, I’ll take bikes into my wife’s photography studio and pick up the camera to capture the details of these frames. It’s good to get them into an environment where there are no background distractions, the focus is purely on the frame. Because SB3505 is in it’s original livery and in excellent condition, it had to have a turn. After a final polish it was placed on the background, in front of the studio lighting, waiting for its turn in the limelight.
The SBDU seemed to stop using their H reference towards the end of 1979, meaning the frames coming out of Ilkeston at the beginning of the 80s would only have the SB frame number stamp and nothing to identify a frame as somehow different. I guess from this point on, the only reference to a specific build or geometry would be shown on the paperwork and build sheets that followed the frame and fork through its production, eventually ending up in Ilkeston’s records. If your frame does have an H reference then you still really have no idea what the ‘H’ was all about unless you have original documentation; that is why I try and measure, document and figure out all my frames.
I’ve been itching to bring the original paint on this frame back to life ever since it arrived last week. And even though SB3505 is already in great condition, it never fails to amaze me how well these frames respond when I give them a wipe with paint renovator and some polish. After successes with other frames in the last couple of months, I had a feeling this one wasn’t going to disappoint…
The process of purchasing SB3505 was super smooth… a late Friday evening email, additional images on the Saturday, deal done on the Sunday morning, packaged on Sunday evening, dispatched and collected on Monday and delivered by lunch time on the Tuesday… A lovely bike at a good price! Packaged together with the Reynolds 753 frame and fork was a Campagnolo Super Record headset, BB and Pista cranks. SB3505 has taken its place in the collection.
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?
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?
The Easter weekend has given me some free time so I decided to work on a couple of projects. SB4409 was the first frame to get some attention. It’s been sitting in the workshop for a few weeks while I continue to look at the amazing profile of these unique 753 oval tubes. The colour has grown on me too and it is now time to return the transfer scheme back to original.
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.
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).
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…
