Why is this still going on??? Anyway, I'm 5' 4" and I ride my bars at 20" high but I wish I had 22" high bars. If their too low when you do a 360 or whatever, you'll feel it when you land.
I've been having really bad back problems recently so bad that i can't ride but when or if i can ever again I'm going to ride 26 just so my back doesn't fuck me. I'm 5'11'' btw
