if some 5'6" kid looks for basic info on bar height they'll end up with 10" rise bars on an 18" frame with 12" chainstay and always be wondering why their bike always wants to do backflips.
Update:Instead of haphazardly buying new bars, I've been playing around with my setup this week by changing the number of spacers on my steerer tube. Adding a few more spacers made my bars a bit higher but it did not give the desired effect. I still felt a bit cramped and things still felt "off".By accident, my bars got knocked forward a bit today. All of a sudden, the front end of my bike felt much better. More room for my knees, better angle for Karl cruisers, whiplashes felt more natural, etc.. So I took out the extra spacers in order to get my bars back to the height I'm used to and I'm instead playing with the angle of my bars in my stem. I've kept them in the same exact place for so long, I figured it was the perfect angle for me but I guess not. It was too vertical, having them kicked forward a bit seems to be helping. I don't do too many things on the front wheel with the bars reverse yet, so that's not an issue yet.So I won't be getting higher bars after all. Like already pointed out, my setup is already fairly tall due to long steerer tube + spaces + 7.9" rise bars.
