the right bars to get all depends on the rider and what you are riding...
if you ride street you want your bars to be 7-8.5''
if you ride vert you want your bars to be just a little taller than street 8-9.75''
with dirt the bars should be around the street height 7-8''
is the lowest of all around 6-7.5''
all around go with GT, Schwinn, or Haro bars
