Profile Design's Carbon Stryke Clip On Aerobar makes adapting your road bike to triathlon or time trial geometry quick and painless, and with the bars' lightweight carbon construction, you'll hardly feel a weight difference on your frame. Using the included extension mount, the Carbon Stryke allows for the lowest, most aggressive body position out of Profile Design's T Carbon line, but aerodynamic body position is not the only goal of the Carbon Stryke. Comfort in your shoulders and triceps while riding stretched out for miles during a race is just as much of a reason to invest in aerobars as the potential speed advantage. Rather than contorting into an aerodynamic position on the drops for 24. 8, 56, or 112 miles, the Carbon Stryke Aerobars let you relax your upper body on the F 19a armrests, which provide the option of four foreaft positions and 15 degrees of rotational adjustment for fit customization. The EVA foam pads provide a cushy platform for the duration of your bike leg. While the Carbon Strykes orient you in a low, race ready position, the upturned, grip shaped bar ends give you more options for hand positioning and better stability over variable road conditions than straight bars.
