Description

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).

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.

Piston SR FAQ

Do I have to have T-slots on my crossbars?

No. The PIston SR comes with universal mounting hardware, giving you two options. HD hardware is available for larger crossbars.

Can I mount the Piston SR using my vehicle’s hitch receiver?

Yes! You can purchase the Piston SR Hitch Adapter separately. This adapter is only compatible with a 2” receiver and will allow you to carry one bike weighing up to 100 lbs.

Can I mount the Piston SR to the side of my IBEX Truck Bed Rack?

Yes! You will need to purchase the Piston SR Mount for the IBEX.  The weight capacity will remain the same at 67 lbs.

Can I mount the Piston SR vertically?

No!! Please don’t. However, we sell a 2” Round Bar Mount that will allow you to mount your Piston SR horizontally to an Owl Van™ rack.

Can I put more than one Piston SR on my roof?

Absolutely! Mount as many as you can fit.

Just curious, what does the “SR” stand for?

Single Rail. We took the design of the Piston Pro X hitch-mounted rack and used a single rail option to mount it on a roof.
