OS20, the ~21.3" tire Size and You

Very nearly the same sized rim/wheel as the 22", the (OverSized)20 is a BMX race specific size. I have seen very few (OS20 wheel-specific) options of frame and fork despite the wheel's introduction almost four years ago. BMX doesn't seem to embrace new tire sizes and standards with the pace that the MTB industry does.

Here is my first OS20 fork, with a .5" lower (than 22") axle to crown, inward angled legs and a 7005 steertube insert.
