I LOVE my Profile Designs Carbon Stryke aeros! I live in Florida with lots of afternoon winds and it was brutal til' I got my aeros. They speeded me up by 2-3 mph.
Keep in mind, these specific bars come with stationary pads, so you will have to buy the flip-up attachments to get the pads out of your way for riding on the flat part of the bar.
They are very adjustable, and pretty easy to install.
Highly recommended.
