Re: Handlebar Stem Size?
My best guess is that what you need is a 22.2 / 1 in. standard. The 21.1/.833 is a hold over from the old days when Schwinn made their bikes using non standard sizes and threads so you would have to go back to a Schwinn dealer to get replacement parts. There are also some older BMX bikes that used the 21.1/.833 stems.
