Re: where to purchase apehangers?
Just a word of advice about high bars. They take some getting used to. Be cautious until you have a feel for the difference in steering. The geometry is a little different so keep that in mind if you've never ridden anything with ape hangers.
Also as was said above, be prepared to buy new cables. You'll probably need them.
