I have an old Schwinn Varsity. As near as I can measure, the steering tube (the part that holds the handlebar - I've also seen it referred to as a gooseneck) has a diameter of 20.5 mm. The steering tube is made of aluminum. I want to replace it with one made of steel. Please don't ask me why.
Are steel steering tubes/goosenecks of this size difficult to come by? I want a steel one that I can use to replace the one that's on the bike.
Thanks in advance.
