Looking to date a Roy Thame frame.

I'm curious about the date of my frame and fork and I hope there is someone on this forum who can shed some light on it. It was once a complete bicycle and has been in the family since it was new.

This is no serial number on the fork steerer, but there is the number 17 stamped on it and a partially discernible oval stamp below the number nearer to the crown.
The bottom bracket shell also has the number 17 stamped on it and there is a partially discernible serial that I make out to be "SW 740727".
I've always thought this bike/frame was from the early '70s. Is it possible that the serial is a date in reverse order of the British style, i.e. 27th July 1974? Perhaps the SW is the frame builders initials?

There was a post a few years back from a lady by the name of Kelly Rowe who was Roy Thame's great niece. Tried PMing her but I think I need to post 49 more times to get that privilege!

Hi Jockie - Welcome to the forums. Everyone is going to ask for pics. Beat them to it and post a few here; it'll help tremendously.

Thanks for the advice tomd7. Nobody has asked for pics yet and there've been no more replies.
Hoping that this photo will prompt a response or two.

I've had the frame blasted, repaired and tracked just recently. Soon I will do a spot of cold setting to space the rear drop outs before having it painted by my urethane paint guy. Here's a picture of the last frame he did for me (it is an old, Tange steel, Nishiki).

Good luck dating it by the serial number. A code, such as you intuit, may be involved; but not necessarily, and not necessarily what you think.

Generally speaking, though, 1974 frame would not have top tube cable guides, nor shifter bosses. I would guess early 80's. (But what do I know).

I commend you for your astute observation rhm but alas I had them added a dozen or so years ago. Frame is most definitely from the '70s, most probably early portion of said decade.

Where's a cipher when you need one?

I'm still on the look out for information regarding my Roy Thame frame, i.e. its date of construction, perhaps even its model name.

Here's a picture of me cold setting the rear dropout spacing to 130mm. Aferwards I aligned the frame with a Park FA6-2 tool ('6' is actually a 'G'). It was relatively easy.


I have a question regarding headsets: by my measurements the headtube is 168mm long, the steerer tube (measured from the base of the fat bit at the bottom to the top of the threads) is 205mm long, so does that mean I can fit a headset with a stack height of 37mm or lower?
Another gratuitous picture.


I was thinking about the Shimano Dura-Ace 7410, would its 37.6mm stack height preclude it? If so, then perhaps someone would be kind enough to suggest something else?

I thought I would add a photo of my repainted and rebuilt Roy Thame.
