Profile's Airstryke S Clip-On Aerobars will make you so quick your competition won't know what hit them. Grab these light aluminum bars, get in a tight, aero tuck and you'll fly faster with less effort. Profile's spring-loaded F-19 arm rests even stay up and out of the way when you're not in your tuck so you can quickly and easily find a comfortable climbing position. With these versatile aero bars your PRs don't stand a chance. Plus, the Airstrykes are easily mounted on most handlebars thanks to Profile's ingenious Multi-Fit System.
