Profile Design's compact Airstryke S Aerobar optimizes standard road bike geometries for triathlon and time trials in the same way as pricier carbon models but with a lower price tag. The shorter extension length also makes fitting the bar simpler, so the aspiring triathlete can clip it on with minimal cockpit adjustments and watch bike leg times decrease. The Airstryke S includes Profile Design's cushy EVA foam covered F 19a armrests. These are used throughout Profile's carbon and aluminum lines, but the Airstryke S features them attached to the ZB Flip Up brackets, which keep the armrests elevated while they're not being held down by elbows. It's obviously not always ideal, but the flip up brackets provide the option of riding on the flats of the handle or basebar if needed. The armrests' reach and orientation can also be customized for an exact fit. The Airstryke S's linked bar ends afford a variety of angles for hand placement, allowing for leverage and control in various situations while resting on the armrests. Finally, the Airstryke S weighs a claimed 542g comparable to competing models in this price range and well worth the added aerodynamic comfort over the course of 56 or 112 miles.
