Let me start by stating that I have never used a riser bar. I have however, used bar-ends since they first came out. That's right, the very first ONZA ends, that were like the expander bolt in the old style stem. Anyway, I just built up a new K2 Lithium, and have been thinking of trying out a set of risers. I notice though, that it seems that when a bike has risers, there are no bar ends. Why not? Am I missing something here?
