just remember... if you go too high with the bars, you will then hurt your lower back and rump, PLUS Dramatically increase the pressure on your hands.

also, when raising the bars too far, your REACH to the bars decreases..... you can end up with a sore back, sore hips, and numb hands.

did you, possibly, buy a bike that plain does not fit you well?

no amount of parts can fix that situation.

and please do verify the stem-bar clamp size before you buy different bars.
you can cut a piece of card paper in an increasingly wider parallel opening to get a "caliper" type measurement of a bar.
i once made a crude "caliper" out of three pencils and a rubber band... chop sticks will work...
