How do you thread jack a '3-year old thread'? lol...j/k

In any case, you can cut just about any North Road bars to the length you want. Most come with longer grip sections than the classic originals to be more compatible with modern brake levers and grips. Just measure carefully and make sure that's the length you want and all your goodies fit...there's no going back if it's too short. Most barcons come with shims to fit in a 22.2mm or 7/8" handlebar.
