If you're looking for a quick and easy way to get more aero benefit from your bike, a pair of aero extension bars are a good place to start. They allow you to get lower on your bike, which cuts the air drag created by your body and allows you to improve power output. The Profile Design T-1 extension bars are exclusive to Performance, and deliver up some of the best value around when it comes to aero. Full carbon fiber construction keeps them ultralight, so they won't weigh down your bike, while the gentle 50-degree ski-jump style curve makes them ergonomically friendly. They are compatible with any 31.8 and 26.0mm handlebars. The molded F35i arm rests improve comfort for the long haul, without causing painful pressure points, and be angled for maximum comfort.
