2025 Kuat Piston® SR

The Kuat Piston SR rooftop bike rack packs all the award-winning technology of our Piston Pro X including all-metal construction, Genuine Kashima-coated piston struts, and no contact on the bike frame. We elevated our hitch rack for your roof and your next adventure.

Description

Meet the Kuat Piston SR roof bike rack. This all-metal, 1-bike rack can safely transport bikes and e-bikes weighing up to 67 pounds. With just one tap, the pneumatic arms open wide and grab your bike tire perfectly, making no contact with the frame. And, just like our Piston Pro X hitch rack, the pistons are coated with Genuine Kashima. We've kept the Fast Fit wheel chock system that changes wheel sizes from 18"-29" in seconds, tool-free. When it comes to security, the 10 mm high-strand integrated cable lock keeps your bike safe while the soft touch outer coating is easy on your bike frame and components. The Piston SR rooftop bike rack comes fully assembled out of the box and mounts to factory, aftermarket, T-channel crossbars, and overlanding bars, giving you more time for the fun stuff. The Piston SR is one of the most versatile racks we make. By combining our Piston SR Hitch Adapter , you can transform this roof rack into a burly hitch rack that will hold heavy e-bikes up to 100 pounds and is approved for RV use with RVs that have chassis-mounted hitch receivers (weight limit decreases to 67 pounds with RV use). We also make a Piston SR Mount for use on our IBEX Truck Bed Rack , enabling you to carry your bike or e-bike on the side of your truck keeping your hitch free. And, with our Piston SR 2" Round Bar Mounts , you can rock the Piston SR roof rack on the back of your van. These and many other features culminate in a bike rack for your roof designed, built, and tested to push the envelope and provide you with peace of mind, and lasting value.
