Thanks for the help
It's a road bike, so i'll look for a 36mm.
Next question (just mention if this should be a separate topic). I'm buying a tube set which comes with a 31.8mm head tube in the kit. I was intending on purchasing the 36mm head tube separately. It's going to be a lugged bike, so what is the criteria with metal type for the separate head tube? Does it need to be identical metal (i.e. steel), and is there a "lug appropriate" type I should be looking for?
