Happy to be corrected, but I have to say this dose not fit nicely with any Holdsworth or RT numbers. I see the wrap over stay and the Club shaped cutouts in the lugs; RT did use these, but most of the examples I have seen had Holdsworth shop numbers, ths frame hasn't. RT used shop numbers up to...
That frame number would suggest a Holdsworth Built CB from 1963. Looking at the catalog for that year it could be a Coureur or European. The other models have different lugs and these two could come in Flamboyant Orange. Looks like it has had the lugs over sprayed at some point. Might be worth...
Looking at the number & its location I would suggest an early Holdsworth built CB from 1959. That said not sure I can ID the model, those window in the head lugs are distinctive, but not common for any model that year. Maybe other can comment.
That number would be a shop build from 1966 as you say. the K can either be stock build or special depending on you point of view as a lot of frame I have found with a K are far from "stock" items. Interestingly the letter is at the start on this number?
This is the numbers I have listed for 1936/46. As you can see the 1946 numbers are significantly higher than 36 and in Feb were already at 2000+ which makes me think they carried over from 1945 which was at ~1600 in Oct that year. The end of the war could explain the inconsistency, but that a...
Yes could well be. Those eyes for the cables are also seen on Shop Built Holdsworths so could have been a modification at some point. These is also a group of Holdsworth numbers using 4 digits from the early sixties when they made a brief break from the traditional 5 Digit numbers of the time. I...
yes, that's 44/15 as I was using up some old components. Just been for a ride on the road and its better for a casual run. I have been using 46/14 on the track and thinking of going to 13t on the rear as I was running out of RPM last week. Not on this bike I might add
First try out at the track. Went ok, bit heavy and low geared. Had to tighten the nut under the seat to hopefully make it more comfortable and stop it sagging. Nice ride though, keeping an eye out for signs of cracking again on the frame top tube.
Yes, I did see that one, passed on it as I have exactly the same issue with a RT Crono to sort out after my daughter took a trip down a pot hole. The RT is definitely worth repairing, but probably at a shop.
Thanks, I have to say I started by assuming the two systems didn't coexist and it was a clean switch over and back again. But, nothing ever seems to be that simple and I guess the honest answer is, we will never really know. I think it would be fair to assume it was a fairly clean switch over to...
It may well end up that way! I guess as I don't rally need another bike I only intend to build it up with spares, could end up as 'garage art' for most the time.
