The Küat 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.
Meet the Küat 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, its 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).
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.

Spent a month looking for crossbars and stumbled upon this ruggedized kit. Purchased in January 2026. Shipping was free and they arrived within a few days. Installation was easy. My rails are silver so not sure yet but I may paint the rails black. I watched a few YouTube videos and one of the guys did that to match with the crossbars. I’ll wait for the nice weather before deciding. Nice looking regardless. Heavy duty. Happy with this product! PS I notice many want to install strip padding underneath the wind fairing. There is plenty of room / clearance so that was not needed in my case.
I initially liked the Alpha II RTT. However after a few uses it experienced a cracked roof. I contacted the company twice with no response. Think hard about buying a product from this company. These products are made in China, which can only compete on price. Very dissappointed in product, its cost, and the company.
