I would reckon 27.2mm but can you not measure it yourself?

Carlton Cobras were normal (tensile?) steel, not 531, my bet is a 25.4 seat post.

I'm with PT1029; I'd assume 25.4mm unless proven otherwise.

cheers

Well the Cobra models I saw had nice wrapover seat stays and natty lugs hence my thinking on 27.2, certainly didn't seem to be hi-ten steel

Even (some of) the cheap Carltons in the 1970's had nice* wrap over seat stays - quite a few of my school friends had them, including a Cobra. They were the cheaper Carltons because they had steel rims/steel seat post/steel cottered chainsets (variously single and double) and often a ghastly plastic saddle. Some of the cheaper ones were even fully chromed.
I think there was a Carlton 10 (orange colour?) which component wise was quite basic (much as mentioned above), but with 531 main tubes (I think plain gauge, so 26.4 dia seat post).
There definately are nicer Carltons of that vintage about with butted 531 tubes etc, but much less common.
(*not as nice as my Holdsworth Mistral stays though)

Thanks for replies,it's 25 or 25.4. Can't be sure ,only have a steel rule to measure. It's nothing special. Picked it up cheap to see how it cleans up. Nice lugs 12 speed all complete bar seat post.

25.4 it will be.
I see you have one of the pretty chrome ones (keep it slightly oiled to preserve the chrome).

Brings back memories of the 70's for me as everyone was moving on from a Raleigh Chopper to a 'ten speed'.

Most of my mates had a green Carlton Corsa and I ended up with a blue Carlton Continental and then the 'rich kid' appeared on the estate with a Carlton Cobra, which everyone was in awe of as it was all chrome with a slight layer of red paint unlike the one in the pictures with blue.

All these bikes were hi-ten steel but in 1973 I remember seeing the Carton Equipe in a catalogue, a lovely light blue colour with tubs and a 531 frame.

Did you know that Carlton were the first frame builders to use Reynolds 531 tubing in the late 1930s and by 1959 Carlton cycles was the second largest manufacturer of bicycles in Britain?

There is a 1973 Raleigh catalogue on Retrobike with just the Carlton bits and I still like the Carlton Equipe, link below:

Happy memories!!

Thanks for the info Granville,I do remember the cobra from the seventies. This one is a bit cosmetically challenged but will attack it with some fine wire wool and oil and see what happens. Will probably lose the black and blue from the frame but hoping the chrome is underneath.
