SBDU 1975 SB95 Frame

1975 SBDU SB95 Reynolds 531 with Nervex Professional Lugs

October has been a good month! It has also reinforced something I say a lot; "you cannot guarantee anything with the Specialist Bicycle Development Unit". Just as I published my blog post about the unique SB662 with Nervex Professional lugs, another one has come along. After a decade of research ...

SBDU Ilkeston SB662 First Look – What Does it Reveal?

Sometimes I buy frames on a whim. In fact most of the frames I buy now are bought with no questions asked. I use my SBDU knowledge to build up enough of a feeling to just go with a hunch. So it's always intriguing to get the frames back onto ...

TI-Raleigh Team Bike Number Use – Is There a Definitive Truth

Is there a definitive truth about what each numbered bike was used for. Every now and then I dip into social media. I often jump straight back out after reading some comments. The problem can be that lots of statements are made, and worryingly, lots of those statements are believed ...

Nervex Professional Lugs SB662 1976 SBDU

Nervex Professional Lugs – A Unique 1976 SBDU Ilkeston Frame Joins my Collection – SB662 New Arrival

Yes, you read that correctly... an SBDU Ilkeston frame with Nervex Professional lugs. I've never seen one before. Even though I've viewed over a 1000 SBDU frames, spanning the entire period of the SBDU, I've not seen a frame with these lugs. That meant I really wanted to add this ...

Alan Oakley’s Raleigh Dynaflite 753 (No Frame Number) – New Arrival

Sometimes I feel the Raleigh Gods look favourably on me and send cool bikes my way. It's either that, or it's my dedication to a decade of blogging and networking to get my name out there that does it. Whatever it is, pictures of Alan Oakley's Raleigh Dynaflite fell into ...

This new 1980 SBDU Ilkeston frame takes my collection past 50, and heading fast towards 60 SBDU and Team frames.

SB3337 1979 TI-Raleigh Team Pro 753 Frame and Fork

1979 TI-Raleigh Team Pro 753 SB3337 – New Arrival

I've had the SBDU blogging blues for the last few months. I've barely posted in 2021. But a rather special recent addition (coming soon...) has kicked me back into it and I'm once again sat in front of the screen with an empty page and images of another TI-Raleigh. This ...

1980 Raleigh 753 TI-Raleigh SB4039 – New Arrival

A 1980 Raleigh 753 in TI colours, there is no better way to start the year. 1980 was maybe the pinnacle for this bike and colour combination! It was the height of TI-Raleigh's success following Joop's victory in that year's Tour de France. Some would say the 1980 TI-Raleigh was ...

Raleigh Castorama Reynolds 753 SBW9262 – New Arrival

I know a bit about SBDU frames, all self taught and researched from my own collection and image library. However, I never profess to being knowledgeable about anything "Raleigh" that falls outside of the SBDU. The era before the SBDU at Raleigh's Worksop/Carlton facility, and then the later Raleigh Special ...

Bob Jackson 753 1975 SB498 From Raleigh SBDU – New Arrival

A Bob Jackson 753 from 1975? Yes, that is how it appears. It's only the presence of an SB frame number that confirms this as a Raleigh SBDU. For many years, the story of this frame was unknown. It is only recently that a clue has been found. However, even ...

40th Anniversary TI-Raleigh Geometry Check Against SBDU Data

There has been a bit of online chatter about the geometry of the new 40th Anniversary TI-Raleigh Reynolds 753 frame. The speculation relates to the geometry of the frame, and specifically, about Raleigh UK's marketing images showing a sloping top tube. Raleigh UK claim that they have followed the spec ...

1974 SBDU SB9 Assembly – Part One

1974 SBDU frames are incredibly rare, so SB9, which still has original paint and Campagnolo Super Record 1st generation components is getting a full strip and clean. I don't think it has been cleaned since it was first built. This is the first part of putting SB9 back together. The ...

1974 Raleigh SBDU SB9 – New Arrival – Home From America

1974 Raleigh SBDU frames, there aren't too many, believed to be no more than 50. My thoughts on the use of the word 'Rare' are documented in my blog, I think it is used too much to incorrectly describe common SBDU frames. But just like my 753 Dynaflite, I think ...

One of my top collecting aims is to document and preserve the originality of SBDU frames, especially the TI-Raleigh scheme. This scheme is one of the most recognisable in cycling history.
