Ok, I have a road bike, the suggestion to go threadless cmae from LBS. As he pointed out if I want to make another change in the future I wouldn't have to go through as much trouble to make the change. One LBS thinks we can get an ok fit without all the techno stuff. I am very mechanical, so the idea doesn't really scare me. I figure if I get in over my head the LBS can get me out of it, as long as I don't break anything. I do have to remove at least one side of the "stuff" to get my bar out.
I'll do some more measurements and get more info later. Thanks for all the input so far.
