LP recommends wiping both the new bar and the things that are going to clamp to it with Isopropyl alcohol. This will clean the surfaces and prevent slipping. I didn't do this at first, but after experiencing some bar-end slippage I took everything off and cleaned the bars and clamps. This took care of the problems. Newer LP bars have a plug in the end to prevent splitting the bar by over tightening bar ends.
Carbon fiber has a reputation as being strong, yet very light.
One thing that I did find disconcerting at first was how much these bars flex. I can get them to move an eighth of an inch vertically. This seemed excessive at first, but I didn't notice it at all while riding. I am sure that this movement contributes to its vibration damping on the pavement. Road shock just doesn't seem to make it to my hands.
