Description
Bike Rack for Roof Top Loading
KUAT / KUAT Piston SR is a high-performance roof rack that allows bicycles to be safely and securely loaded onto the roof top without touching the frame, thanks to OneTap™ hydro-pneumatic tire arms that do not grip the frame.
In addition to the high durability and high grade finish of the high quality all-metal construction, the front and rear arms and pistons are coated with Kashima Coating for superior wear resistance.
The FastFit™ system provides secure, tool-free fastening and unfastening with a single tap.
The FastFit™ system allows smooth, one-tap fastening and unfastening. It is also compatible with a wide range of base carriers, including square bars, aerobars, and T-slots.
