I don't have such a thing. Was thinking along the lines of a petrol soaked rag on a stick :lol:

Weird, as all the late 80s Reynolds ATB seat tubes, including Magnum, are 1.0/0.7, giving a 27.2mm internal on a 28.6mm OD tube.

Possible cause?:
My 86' Pioneer cracked through at the ST/TT joint where it had distorted from the fillet and had been reamed out fully to 27.2, leaving very little thickness of metal. The later frames had the reinforcing sleeve/lug at this joint, allowing the tube to be reamed properly. I think it might depend on which model of reinforcing sleeve was used. Some have the parent tube running fully through, probably running 27.2mm. Others have a straight shoulder inside about 10mm up from the bottom edge, the rest of the internal bore is from the lug not the tube, so it's the outer sleeve/lug that dictates the seatpost diameter, not the tube itself, probably 27.0 or 26.8mm.

Looking at this small selection we have between us, I also suspect Andy built the frames with whatever came to hand...or perhaps sometimes didn't ream the distortion fully out, and sometimes didn't put a sleeve on at all (the-duke's).

All the best,



Good Info Dan, id be interested to see the tube specs for the Columbus tubed Overburys if you have that to hand..?

1989 Columbus specs here at Equusbicycle.

They might have done some Cromor OR frames, but I'd have thought it would mostly be Niva OR and possibly some Max OR.

All the best,

Tying up some loose ends - my Pioneer as it came back from the paintshop and evolving into a specification fit to ride at Mayhem...

Now for something a bit different, my 1994-ish Overburys race bike, fully fillet brazed and with no apostrophe. Original paint and decals, hence the battle scars.

Apologies yet again for my appalling photographic skills. :oops:

Nice indeed. Colour is just like my old saracen kili of that age.

Is that all xt?

Very good build.

I have replaced the decals since these pics were taken but it remains very much a work in progress at the moment :roll:
