I ride a Kona Hoss Deluxe. I recently went back to the store to get a riser bar with maximum height (out of the QB catalog) because of wrist pain. It came in. They put it on. And while the pain is greatly reduced I'm finding that it's still not high enough.

While I'm investigating the Mary bar from On-One in the UK, I was thinking of putting a BMX handle bar like on the Kona Humuhumu,etc. Would this be a good idea?
