Bit of a shot in the dark here, but would anyone know what type of BB thread I'll find on a 2003 French MBK road frame with Columbus Aelle tubing ?

I'm just not sure if it'll be British Thread of Italian thread ?

The bike's not here, it's in France and I'm fitting a new BB & Chainset to it once I'm over there, but need to buy the BB first.

    Just to confuse you there is also a French thread - 1mm smaller that Italian, but thankfully obsolete! It's most likely to be BS adopted as ISO - start by measuring the width of the BB shell - BS is 68mm wide whereas Italian is 70mm. Italian is RH thread on both sides whereas BS has LH thread on LH / fixed cup
    Make mine an Italian, with Campagnolo on the side..

    thanks - that's what I was hoping.
