I'm going to build a lugged steel track frame, and I'm trying to decide what BB threading to choose.

Which is most common?

English is more common, except on old world Italian bikes like DeRosa, Pinarello, Colnago, Masi.... any of those type builders tend to exclusively use Italian. If you have a choice, go English. I suspect it is doing to be determined by the tubeset you buy, but if you are offered the choice, go English. The drive side won't loosen itself under normal riding like an Italian BB can.

why do people use Italian then?ColnagoFE

Is it just tradition? Seems like a pretty dumb tradition. Any advantages to Italian?

They are pretty minor, but there are a few. First, you don't have to worry about putting in the drive side cup backwards and cross-threading the frame. Both cups go "righty tighty, lefty loosey." An English thread system you have to remember your drive side cup and non-drive side pedal are left hand thread... it can be confusing. Inexperienced people won't try to hammer a cup into a frame thinking they are taking it out if they don't know that one side is different. And if you use a torque wrench to put it in, it will stay in, you just have to put it in as tight as they tell you to.

Also, if you destroy the threads on an English BB shell, you can retap it to Italian.

Those are about all I can think of... but it's an older design and some companies don't want to change. Colnago still uses a 1 inch headset and says there is no real advantage to go 1 1/8th on a road bike. They tend to make the best bikes in the world.. they are always in demand both by pros and average joes, and so why not build the way you want to and are used to instead of how fashion dictates you do. Colnago has set the fashion of high end bikes for over 30 years now... if they want to use 1 inch headsets and Italian bottom brackets... cool, let em!
