I missed the single color distinction in the original post.

Marinoni did apparently build some USA bikes which were in Raleigh livery, including the one carpenter used in the 84' Olympics, but this one is SBDU.
I think a comparison would be fun - another member has a similar one as well...I think Michelangelo.
Sheldon has some background:

The red/yellow was by far the most common '70s color scheme. There was also a single-color champagne/gold, and a dark blue w/black panels scheme that was originally done for a local British team, then became a standard option. The red front/black stays became common in the US in the '80s. I don't recall ever seeing a Silver Mink SBDU original finish, but dealers/distributors may have been able to order non-standard colors.

It's clearly one of Gerald's frames, and it obviously was built up. There's a ding on the down tube, and I saved it from the scrap heap. No tubing sticker - I don't recollect if I checked the seat tube dia, I don't know what it weighs, it's just been sitting in my junk box for 30 plus years as I've never gottenaroundtodoingsomething with it.
There's a few here who know more about SBDU and its products than I. Thoughts?

This is my Mid 80's Raleigh Team Professional, Reynolds 753r, with number hanger. Campy Super Record.

Weigh the frame. Bare frame without fork should weigh 1600-1700 g for 753 (or 531 professional). 531 bare frame w/o fork should weigh 2000-2200 g.

How common were the fast back stays? I haven't seen these on many other SBDUs.

Here is some more info about available RTP colors and fast back seat stays. This is for the 1984 model year. If I read it correctly the fast back stays were on the Reynolds 753 frames.

LOL, I did that too, and made the guess that the latter was Metric and the former was Imperial...

Weight is the definitive test to distinguish a 753 frame from a 531 frame. A $25 kitchen scale will do.

I believe below is what is generally acknowledged as the closest approximation of production. Based on that, the OP's frame would likely fall in 1977-1978.
YEAR Frame No
1976 500
1977 1200
1978 1900
1979 2800
1980 3500
1981 4100
1982 4900
1983 5500
1984 6300
1985 6900
1986 7700
Closed 8300
That is a top of the line frame AKA Team Pro. Got the fork? They could be any color the customer wished but for a lot of reasons the Team Pro colors prevailed for many. My own SB1016 is below:

That would be 753R, not 753. Big difference, imho. The creation of 753R (and T) occurred in 1983. Imperial-diameter stuff (so it will take a 27.2 or a 27.4 mm post), and not as crazy-thinwalled as 753, which takes a 26.8 or 27.0 post. Still great tubing....

I don't know if it's something with Phtobucket or the way this site is set up but I seem to have a great deal of difficulty posting larger photos here. I don't seem to have problems on other sites. Here goes:
History: I picked up 2 SBDU 753 frames in 1999. One was a 1978/79. The other was this one, a 1984 or thereabouts. The '79 frame I sold off in 2002 or 2003. The newer frame was built up once and used as a showpiece in a bike shop in Boulder CO. The frame arrived and I didn't realize it at the time but the driveline side dropout was damaged in shipping. Cold setting resulted in a fracture at the dropout adjuster screw. So it needs to go off for repair. Other than that it's almost a perfect frame.

a minor question for all the tube investment experts -
it is posted above that sbdu launched in 1974. it strikes me that this is right about the time of the kessels revelations/embarrassment. is that correct? could sbdu have been launched wholly or partially in response to this wee ado?
had not heard about sbdu prior to reading thread so please excuse if this is a stupid question.
thanks for any information(s).

The seatpost diameter is 26.8 on my daughter's RTP.

Just to add to your (correct) info., you will see numbers higher than 8300 (up to close to 10,000) but they were not made at Ilkeston after about 8300, rather back at Nottingham (or Worksop?) by very skilled builders, so still quite nice frames, just not 'real' Ilkeston Team Pros....

No need for apologies. The number/date list I provided was presented as an approximation. We learn things frequently about SBDU and Ilkeston.

Going back to the beginning, I took the frame shown to the PO for a weigh in, 1.87 kg. So, what say you?
