I have an old Campagnolo from 1997 that I want to turn into an single speed.
My problem is finding a kit that will fit the freehub. The outer diameter of this freehub including teeth is 34 mm, but when I find a kit like this one http://www.ebay.com/itm/400876993505 the dimensions are off. The cog I bought from ebay has a smaller diameter that the freehub.
What should I be looking for when it's an old 1997 screw-on freehub? Would it be easier just to replace the freehub, and if yes, which one should I pick to make sure it's going to fit?
