Profile Design ZBS Ski Bend Aerobars. Downhill ski racers certainly know a thing or two about getting aero, plus making every second count, and that speed friendly philosophy is fully present in the Profile Design ZBS Ski Bend Aerobar. The ZBS brackets deliver a lower arm position while the F 19 adjustable anatomic armrests ensure a perfect, dialed in fit to best cheat the wind. It's not enough to be aero, though, but don't worry as the forged 6061 T6 aluminum throughout is both lightweight and durable so you know they're built to last as well. Mount these on a road bar or bullhorn bar and get ready to blaze through your next ride against the clock.
