eBay… it is a place I try to avoid. I like to find bikes and frames that haven’t had much exposure to the internet. eBay links containing interesting vintage bikes are shared across social media, and before you know it, the item has been seen by thousands and hyped up to a point that the auction escalates and bidders get into a frenzy pushing the prices up beyond anything sensible. I enjoy the hunt, searching and discovering SBDU bikes that have been hidden away. But I do keep an avid eye on eBay and every now and again a little gem crops up to pique my curiosity. SH377T was listed with no reserve and a low starting bid so I saved it into my ‘Watch List’ thinking it would go the way of so many others and spiral out of control… but it didn’t!
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.
I have several frames and bikes in my SBDU collection that constantly vie for top spot. Should top spot go to JR178T, my Jan Raas frame? Should it be SB632, the earliest known Reynolds 753 SB numbered Track frame; the Beryl Burton connection on that frame alone should surely make that a contender? What about the bike that started all this blogging, SB4059, my immaculate 1980 Team Pro 753, or how about SB6398, a time capsule of an original bike with a 753R SBDU frame and a complete Campagnolo Super Record 50th Anniversary Group. Then there is the rare SBDU 753 Dynaflite with Ovoid tubing, SB4409. But what about SB664, an early Carlton Capella lugged Imperial tubed 753 frame, that is also a possibility.
It is a constant battle! And now another frame is fighting for top spot… SB1500, my newest arrival, this has so many possibilities that give it the right to be up there with all the others too.
After working out that SB664 was built from an early type of Imperial Reynolds 753 tubing, I wanted to use the calipers and metal rule again to try and figure out what type of use the frame was built for. Was the geometry designed specifically for Road or Time Trial; the outward appearance such as the frame transfers suggest that it is probably an SBDU Time Trial frame. SB664 is an early SB numbered 753 frame and was probably ordered in first part 1976 or even in late 1975. Reynolds 753 was brand new, it had only just been shown to the public in trade shows and it wasn’t widely available outside of the TI-Raleigh team. So what was this frame designed to be?
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 is no long winded waffle from me on this post, at least that is the intention… it’s hopefully just a short introduction about a new addition to the collection. There WILL be many more posts about this frame; this frame could fill my blog with new content for an entire year. It has some rather special and unique combinations of features that I have not seen on any other Specialist Bicycle Development Unit (SBDU) frame.
Back at the beginning of May, I had a weekend of frame repairs! SB4409 had new transfers and a bit of clear coat, while SB6560 had new gear lever bosses brazed into place. Before I tidied up and put the files away, I thought I’d squeeze in one more project; SB632. This is a special little frame that has had a modification at some point in its life to add a gear hanger and increase the thickness of the rear track ends to accommodate road wheels and gearing. This is the first step to restoring SB632 back to how it was originally.
