This is one of those upgrades that you hear very conflicting advice. Numerous people love carbon bars and say they are very noticeably more comfortable. About as many people say they can't feel any difference. My guess is it just varies by person and bike. Makes it hard to decide to spend the money because who knows which you will be. My personal take is it's not worth upgrading for upgrading sake, but if I decided to replace my bars for some reason I would probably go ahead and try carbon.
