The Yakima Whispbar Through Bar Rack Kit lets you utilize every precious inch of the crossbars to carry all the gear you'll need for a weekend on the trails or out in the snow. As an added bonus, the crossbars' aerofoil shape looks a bit like an airplane wing and cuts smoothly through the air for a quiet and energy efficient ride.

 The half kit comes with one crossbar, two towers with SKS locks, and two SmartFoot mounts with cushioning pads.
