Borrowing the quick release air arms from their Piston Pro X hitch rack, the new Kuat Piston SR adds a roof rack option.
The Piston SR (for Single Rail) attaches to all compatible crossbars, including T-rails, then secures your bike to the tires, without the risk of scratching your frame or fork. When it’s time to roll or load the bike, just press the OneTap release lever and the arms automatically open for quick escapes.
Like the hitch bike rack, the Piston SR features Kashima-coated sliders for smooth, durable opening and closing. The wheel chocks adjust without tools to fit different wheel diameters, with tires up to 5″ and a wheelbase up to 53 inches.
The rack has an integrated 10mm (thick) cable lock for lightweight security, pulling at the end and hooking into the center of the shelf.
The rack weight is 22 lbs and its capacity is 67 lbs, making it perfect for e-bikes (assuming you want to lift them onto your roof). It comes fully assembled, MSRP is $449.
