Default Re: how to lengthen steerer tube on a bicycle

i double sleeved it because i'm making a really fast bike, and the last thing i want is a broken fork at 50+...
7/8" cold roll fits in them nice and tight if you realy want to stiffen them, also you can use the cold roll to streighten them helps keep it from flatening the tube if you put it in a press..............Curt
