  • Limited lifetime warranty

These low-profile Inno Aero crossbars let you build a stylish, aerodynamic roof rack for your vehicle. The crossbars require 4 Inno Flush or Through feet to mount the rack to your roof. You may also need a custom fit kit to mount the crossbars. Built-in T-slots in the tops of the bars let you easily mount carriers and accessories on the rack. Flexible rubber strips in the channels keep out dirt and require no trimming or adjustment. The crossbars are also constructed of strong yet lightweight aluminum so they won't rust.

Aerodynamic Shape

These lightweight bars have an elliptical shape. This aerodynamic, low-profile design helps to reduce wind noise and drag when you drive. This means you won't need to add a fairing.

Strong, Durable Construction

Inno Aero Internal Extrusion

Inno Aero crossbars are constructed of sturdy, lightweight aluminum. Internal extrusions add strength and structural rigidity without adding a significant amount of weight. The bars are rustproof so you can leave them on your roof all year long, wherever you go. The sand-blasted powder coat finish resists corrosion, scuffs, and scratches. And the matte black color will look good on any vehicle.

Slide-On Installation

Inno XS Slide On Install

Each crossbar has a channel in the bottom that lets you install Inno feet (sold separately). Slide the channel cover over to reveal a mounting hole for the foot. Clip the foot into the crossbar and then slide it into place along the channel. Built-in bar end stops in the channels will keep the feet from sliding off the ends of the bars.

Inno Aero Locking Stay

To complete installation, mount the feet to your roof. This may require a custom fit kit (depending on your application). Attach the locking covers (included with the feet) to secure the roof rack to your vehicle. Locking the covers also secures T-slot-mounted accessories to your crossbars.

Channel-Mounted and Clamp-On Accessories

Inno Aero T Slot

This bar has a built-in T-slot that allows you to mount bike racks, watersport carriers, ski racks, and more. The EZ-Slide rubber strip in the bar lets you mount accessories without the need to remove or trim the strip. Just press down on the ends of the flexible strip and slide your accessory's mounting hardware into the T-slot. This strip has a plastic coating so it's easy to slide T-bolts along the channel. The strip runs the full length of the bar, so it helps keep dirt out of the channel when you're not carrying accessories.

Inno Aero with Clamp On Accessory

You can also attach most clamp-on accessories to the bar, and the rubber strip provides a no-slip cushion for any accessories that rest on it.

Installation went pretty smoothly. The
trick is to fully understand each step before moving to the next. There are a lot of small parts which at first was a little intimidating, but soon I was able to "get with it". I love the finished product and think you helped me get a good deal. Thank you for that

Ford Edge

Easy install on 2021 4runner off road premium. Looks clean, matchs blacked out on white, eadges of chrome cap matches mirror accents and tail lights. Etrailer video was simple to follow. What it didn't show was the foam rubber strips that you put on under the t tracks slot. With cover off and top most flat part of clamp to edge of bar measures about 5.5inches. Make sure the clamp is flush with bar when you measure. Overall looks good

Nissan Murano

Tule and Yakima did not have a rack for my Nissan murano. So it was a blessing to find the immo rack. It seems like it can fit any car model. It's strong and secure. I feel my equipment will be safe with this rack.


Installation was a little tricky but once the "feet" were attached to the roof and the bars properly spaced, everything wrapped up very well.

There is no noticeable wind noise with these installed.


These crossbars are awesome!


Definite five star….having all glass roof we were handled super, guided from phone to delivery , video to guide are installing, quality product thank you we’ll be back

2017 Lincoln MKX

We recently purchased 2 kayaks & Thule roof racks from our local outdoor store.

After waiting 2 weeks for our roof racks and J bars to come in we found that the Thule racks did not fit our 2017 Lincoln MKX and they didn't make any racks that would. The vehicle does not have roof racks and has a moon roof.

After a couple of days searching the internet we discovered We found the Inno roof racks, but still was not sure they would work. We spoke to a repesenative and he assured us that the racks we chose would fit and the Thule J bars we did return would also work. As you can see by the photos 2 days later we were happy Kayakers.


One was extremely hard to get on compared to the others (not sure if it was rough machining or something), but once it was on, all was good.

High quality metal. Aerodynamic shape - I could not hear ANY wind noise being generated.


The trunk arrived in Poland in perfect condition. Packed in a hard cardboard box, it has not been damaged in any way. The trunk is made with great care, it is nice, solid and quite quiet. Thank you for a successful purchase.

2014 Toyota Prius

These bars look amazing on my 2014 Toyota Prius V. Held up the two kayaks extremely well.


They were so helpful. Geoffrey got me the parts the next day and the roof rack works great. Easy assembly. Just needed a little muscle power to click the final pieces together. Everything else was an easy bolt.

2016 GMC Yukon

Easy to order, easy to install and quite effective in it's use. Thank you.

Review from a similar Elliptical Roof Bars in Roof Rack

Once again delivers. Finding a crossbar solution for my 2021 Lexus GX 460 was far more challenging than expected until I visited the site and found exactly what I needed. The fit kit worked great and the quality of the feet and crossbars on par or better than other brands (who dropped the ball on having a product available for this vehicle). The rack is on, secure and now carrying my Thule cargo box. Very happy.


Review from a similar Elliptical Roof Bars in Roof Rack

Shipping and packaging was very good and delivered on time!
Glad I went with the Aero cross bars for the less wind noise!


Review from a similar Elliptical Roof Bars in Roof Rack

Originally, I was waiting for the Yakima crossbars to be restocked for my GX460 but decided I couldn’t wait it out any longer and went with the Inno’s aero set. Overall, they look great, fit great and seem to be very good quality. I was able to assemble the rack myself, it took me about an hour and half, I wish the installation was a bit easier but after watching the video from etrailer it all came together perfectly !

Ask the Experts about this Inno Roof Rack

  • Placement of my Inno Roof Rack System on my 2017 Lincoln MKX
    When installing the Inno Aero Crossbars part # INXB138-2, Inno Through Feet for Aero Crossbars part # INXS250 and the Custom Fit Kit for Inno Crossbars part # INK676 we must follow the installation instructions exactly. This is where the rack was designed to to be installed and tested for performance. Mounting it in any other location would void the warranty and may lead to damage occurring to your 2017 Lincoln MKX.

  • Best Roof Rack Option For 2020 Nissan Rogue With Naked Roof
    The best roof rack option for the 2020 Nissan Rogue with a naked roof is Inno Aero Cross bars # INXB138-2 with Inno feet part # INXS250 and custom fit kit part # INK466. The Inno bars are low profile aerodynamic bars that are designed to cut down on the wind noise that you may experience with other brands available. The built in t-slot makes it easier to mount accessories like bike racks and water sport carriers. Other brands do require cutting the rubber strip in the t-slot to make room...

    The Rola Sport Series Roof Rack with GTX Mounting System for Naked Roofs, # 59733, is not a confirmed fit for your 2014 Toyota Camry. The good news is, there are a number of options available to you, and I recommend the Rola Crossbars # INXB138-2, Feet # INXS250, and Fit Kit # INK872.

I've linked a photo of the way these attach to the rails and you can see the clamp that will attach to the outside of the flush mounted rails on your X5, and provide a secure fit.

    It looks like the 45 lb weight rating that you're seeing is only for the OEM crossbars that came with your 2017 Ford Escape. For your application I recommend going with the Inno roof rack because it has a higher weight capacity at 140 lbs, an easy-to-use T-Slot system for mounting accessories, and the legs come with locks so you can deter theft of your roof rack system: 54" Inno Aero Crossbars - # INXB138-2 Inno Through Feet - # INXS150 I'm attaching an installation video of this setup...

  • Recommendations For Carrying Two Roof Bike Racks On A 2022 BMW X4
    I reached out to Inno and the # INXB138-2 and # INXS450 have not yet been approved for a 2022 BMW X4. However, I also reached out to Yakima and Thule, and Thule did have something that will fit your new vehicle. To do this, you will need to start with the Fit Kit for Thule Evo Flush Roof Rack Feet # TH186007. These are specifically designed for the flush rails you have on your X4 and will allow you to get the Evo Flush Rail Feet # TH710601 attached. From here, you will need the Thule WingBar...

    For your 2016 Toyota 4 Runner, I recommend the Inno Aero Crossbars # INXB138-2 and Inno Through Feet for Aero Crossbars # INXS150. For your Kayak Carrier, to avoid the J-style, I recommend the the Thule Stacker Kayak Carrier System # TH830. For a bottom riding option, I recommend the Thule Top Deck Rooftop Kayak Carrier System with Tie Downs, # TH881. The only issue you may run into with this style is the width of your kayaks.

    You have the right foot pack and the Thule ProBar Crossbars - Aluminum - 69" Long - Qty 2 part # TH713600 will work on them and have overhang over each side. A key consideration here besides crossbar space is that the 2019 Nissan Rogue has a service load capacity of 165lbs for the roof so the combination of your roof rack and 4 kayaks/2 kayaks & Rocketbox combination total weight would need to be under that amount to safely transport. As long as the crossbars you use aren't wider than...

  • Best Roof Rack and Surfboard Carrier for a 2020 Toyota 4Runner with the Raised Side Rails
    While it is true that price does typically reflect quality, when it comes to roof racks you will be just as happy with the performance of a middle-of-the-road aero-style rack as you would with one of the ones at a higher price-point. Because of this I highly recommend the Inno roof rack for your 2020 Toyota 4Runner with the raised side rails. This consists of 54" Aero Crossbars # INXB138-2 and the Through Feet # INXS150. It not only gives you the aerodynamic crossbars but the feet also...

Instead, I recommend using Inno Aero Crossbars, part # INXB138-2. They're aero-style bars with T-slots, so they're compatible with most accessories. To mount them, you need the Through Feet, part # INXS250, and the Custom Fit Kit, part # INK153. This doesn't require drilling since the fit kit mounts...

    We can get your 2016 Honda CR-V with a naked roof set up with a roof rack to carry a couple kayaks, and the option I really like is from Inno. The reason I recommend the Inno is because it uses long 54 inch crossbars, which not only gives you enough space for mounting two kayaks, it also makes mounting them easier, particularly on J-carriers like the etrailer J-Style Kayak Carrier # e98878. The closer you can get the kayak carriers to the edge of your CR-V, the simpler it will be to put...
