I built my road bike with a set of them....If I could do it again I would not purchase them. A lot of money for minimal to no gains. There are cheaper alternatives to wing shape bars and in my opinion the wing shape does not offer much in comfort compared to a round bar.

One poster above mentioned the angle of the wing...my experience is that the angle causes strain on the wrist. To set the angle flat the bottom of the drops will be pointed at an upwards angle which is functionally not good but looks bad too.

It was a also huge pain the arse to fish the housing through the bars. If it was just the brakes or the shifters it would have been fine, but 2 sets of housing on each side was a real pain to get set up.

The extra rise mentioned is nice I guess, but that can be controlled with proper stem height....if you cut your steerer too short these might help save the cost of buying a new fork...but the rise and the wing shape limit what and where you can mount things to the bar.

Again, I think they are expensive for what they are. They look cool, so if that is what you are after then go for them, but other than that I would recommend putting your money into something else.
