Video Transcript for Thule Roof Rack XADAPT8 Review

Speaker 1: Today, we're taking a look at the Thule Xadapt8 load bar adapter for the Criterium bike rack. This allows you to mount your TH598 or TH597 bike rack to Thule load bars with integrated channels such as the Rapid Aero, AeroBlade, and Xsporter load bars.This part number comes with three 61 millimeter T-bolts and one 35 millimeter T-bolt, and it comes with your set of detailed installation instructions to help walk you through the whole setup and installation process step by step. Basically, for the Super G, that's TH597, you'll use all three of the 61-millimeter T-bolts. And for the TH598, the Criterium, you'll use two of the 61-millimeter T-bolts and one 35-millimeter T-bolt. So it shows you exactly what you need to do to get it installed and to get it set up. And on the back of that first page is the rest of the setup process.So it goes through step by step, shows you exactly what you need to do, exactly what you need to use and walks you through getting everything attached and setup through your application.

But again, this kit is designed to allow you to mount your TH598 or 597 bike rack to Thule load bars with channels, again, such as the Rapid Aero bars, AeroBlade, and the Xsporter load bars from Thule.That's going to do it for today's look at the Thule Xadapt8 load bar adapter.

Awesome easy to order and track. Great support from the company. Easy to track your package from order to delivery.

These thule adapters work amazing and allowed me to attached my Criterium bike carrier to my Rhino Rack aero bars. I was afraid i would have to return the bike carriers but these adapters saved me and were very low cost. Totally worth it.

Tried unsuccessfully with a phone call to etrailer to get information before placing the order on the thread pitch (thread count). Despite not getting the answer I decided to take a chance and order. These we the perfect size for my needs but the thread pitch is different so the standard Thule knob will not work on these. They are a M6 diameter but the threads are much finer, I believe a 0.7 instead of the standard 1.0. I have searched for M6 wing nuts of any brand with a thread pitch of 0.7 but cannot find any. On a positive note I did receive the shipment in a timely manner.

The product (Xadapt8) was just what I needed. Shipping was very fast, under 3 days. I have the Thule Aeroblade roof rack system and needed these in order to mount the Criterium bike rack.

Etrailer is a great company to do business with! They replaced this item that I ordered when it was lost in shipment and did not reach us before we left FL. The specialized screws are exactly as ordered and are Thule parts. Thank you etrailer, we will do business again in the future!

Simple but very good and safe solution allow you to use ao older bike rack with New and better Aero bars. On top of that, your website and support is outstanding and the shipment arrived as expected based on your promise. Thank you

Review from a similar Xadapt in Accessories and Parts


Adapter works perfectly on 2020 Audi Q5 (VW) But didn’t need all the xtra hardware for Thule Big Mouth bike rack. (Ca 2003) . 3 of the short bolts per unit did the trick and of course the rubber inlays to prevent scratching and rattling are perfect.

Review from a similar Xadapt in Accessories and Parts


I used the XADAPT2 kit to convert my Thule Bigmouth bike carriers to fit the OEM Volkswagen cross bars on my 2016 Jetta sedan. The bike carriers originally had clamps to fit the Thule square cross bars, and this kit allowed me to convert the carriers to fit in the T-slots of the VW cross bars. The kit was originally designed for older VWs, but the T-slot dimensions have not changed for the modern VW cross bars. I would venture to guess that the kit should work for the OEM cross bars of any modern VW rather than just the Jetta, since the VW bike carriers are not model specific. A great quality kit, and perfect for my application!

Review from a similar Xadapt in Accessories and Parts


I used this to fit an old (1994) Thule Big Mouth bike rack to a factory 1994 VW Jetta Votex roof rack. The bike rack was originally fitted to a Thule square tube rack. Fits perfect, but has many extra parts. The only parts that were needed my me were 3 square plastic tabs and 3 of the "T" bolts, so there are many left overs, but for the price I don't think I can complain much. I'm glad the kit was available. Instructions were pretty useless.

Review from a similar Xadapt in Accessories and Parts


Very good quality product with a little problem. Track is connected to a bracket by one bolt and the bolt was getting loose. I had to buy a little bit longer bolt, use a spring washer and washer, problem solved. See picture. Assembly instructions could be better.

Review from a similar Xadapt in Accessories and Parts


I purchased the THXADAPT3 to be able to install my Thule 834 hull a port kayak rack onto the 1.5" square bar of my Adarac Custom Truck Bed Ladder Rack - Steel with Aluminum Crossbars. I believe it will work but I wish the bolts were a bit longer. See images. I have been satisfied with etrailer's support and service. Thanks

by:

Review from a similar Xadapt in Accessories and Parts


These bolts should be included in the Thule Kayak carrier kit, since the kit claims to fit factory roof racks with 2" diameter cross-bars. They won't fit unless you have these longer bolts.

Review from a similar Xadapt in Accessories and Parts


Well, if you rely strictly on the Thule instructions, you're in for a real treat. I would actually claim it would be nearly impossible to install your 599XTR on aerobars using just those instructions. I ended up looking up some accompanying videos online to assist with my conceptualization of the install process. Once I figured it out, it was VERY easy to install the adapter kit and the 599XTR Wide Mouths. Nice engineering.


Comments
Yeah, top notch item. You guys are my go-to for anything rack and trailer related, for sure.

  • How To Mount Thule Criterium Bike Rack On Thule AeroBlade Crossbars Inside Channels
    In order to mount the Thule Criterium Roof Mount Bike Rack part 898 on the Thule AeroBlade Crossbars in the channels you will only need to obtain the Thule Xadapt8 AeroBlade and Xsporter Load Bar Adapter for Criterium Bike Rack part # Xadapt8. The Xadapt8 AeroBlade Adapter will then mate up to the Replacement Barrel Nut fpart # 853-0446-06 as they both have M6 threads. I have attached a photo to assist.

  • Carriers for Axes, Shovels, and Other Tools for a Thule AeroBlade Roof Rack
    The bolts included in the Thule Xadapt8 adapter # XADAPT8 do fit the T-slot that is in the tops of the AeroBlade bars. The only question that remains is what are you going to thread them into to hold your various accessories? You might instead consider Rhino-Rack accessory holders # RRRMPHU. They are T-slot mount or will clamp around roof rack crossbars. They are versatile making them a solid option for you. I have linked a video review for you.

  • What Size are the T-Bolts in the Thule Xadapt8 Kit
    I went out to the warehouse and pulled an Thule # XADAPT8 kit, an M6 barrel nut, and a regular M6 nut. I tested all the parts together and found what I think is the problem you are having. The bolts are M6 bolts but they are fine threaded. You are probably finding nuts that are coarse threaded. The Thule barrel nut fit perfectly which is how I know they are M6 bolts. The other nut would nut screw onto the bolt because it was coarse threaded meaning the spaces between threads was larger...

  • Which Adapters Do I Need to Fit a Bike and Ski Rack to My 2015 Volvo XC70 With Factory Roofrack
    I checked with Thule and they tell me that your roof rack is not a Thule roof rack. However, that doesn't mean the hardware to connect your Thule products will not work anyway. But you'll want to measure to make sure first. I went out and measured the adapters that are made for your Criterium which are # XADAPT8. The head is 3/4 inch square and 1/8 inch thick. The shaft of the long bolt is 2-3/8 inches long and the shaft of the short bolt is 1-3/8 inches long. See the picture I've...

  • Can the Thule Criterium Bike Rack be Made to Fit Factory Crossbars on a 2012 Audi Q5
    In order to use the bike racks you have with the thick crossbars on your 2012 Audi Q5 you would have to use the Ride On adapter # TH532. However, the Ride On adapter is designed to fit up to 3-1/2" x 1-1/2" crossbars. So for it to fit you would have to use longer screws so the feet can attach to the bars. Screw # TH853526902 is 1/2 inch longer and the same M6 size as the ones that come with the adapter so it would fit bars up to 2 inches tall. If even longer hardware is required it would...

  • Mounting a Thule Criterium Rooftop Bike Rack on a 2016 BMW X3 with OEM/Factory Crossbars
    You'll use the XAdapter 8 kit, part # XADAPT8 to replace your mounting hardware with channel mounting bolts. Because of the cut and shaping of the bars, the channels can look different, but tend to end up within an 1/8-inch of each other in terms of size, and the bolts tighten to the top of the channel when they're properly installed, so your width ends up not mattering much in the end.

  • How To Mount The Thule Criterium 598 Bike Rack Onto Yakima Jetstream Crossbars
    Yes, you are absolutely right. The Thule Xadapt8 AeroBlade and Xsporter Load Bar Adapter # Xadapt8 for your Criterium 598 bike rack is compatible with Yakima Jetstream crossbars with the top track. Luckily, the common roof rack brands all use the same universal T-slot channel which is helping you out in this situation. There have been some accessories that did not fit the common T-slot channel but usually you can file down the T-bolt ever so slightly in order to get the T-bolt to fit the...

  • Is the Thule Criterium Bike Rack Compatible with the Rhino Racks ROC25 Aero Crossbars?
    I confirmed with the manufacturer that the Thule Xadapt8 AeroBlade and Xsporter Load Bar Adapter for Criterium Bike Rack # Xadapt8 will work for the channel-mount system in the Rhino Racks ROC25 Aerobars # RR26XR. As far as what's included in the Thule Xadapt8 AeroBlade and Xsporter Load Bar Adapter for Criterium Bike Rack # Xadapt8, the bolts that come in that kit are all you need, so you won't have to purchase any additional additional fasteners.

  • Can the T-Slot in Thule AeroBlade Crossbars be Used to Attach Any Accessory
    Thule, unlike Yakima, does not have a special device that attaches to the bars and accepts numerous accessories. Basically, it depends on what you want to fit to the AeroBlade bars. Thule makes several adapters, called Xadapt? where the question mark would be a number depending on which adapter it was. If you can tell me what you are wanting to attach to the AeroBlade bars I can determine what Xadapt you will need. If it is a non-Thule item then it may not fit. Or if you modified...

If you have this bike rack and are needing to make it compatible with your Thule AeroBlade Load Bars you will actually need the Thule Xadapt8 Load Bar Adapter # XADAPT8.

  • Thule Roof Bike Rack to Fit 2016 Tesla Model S with Whispbar Roof Rack and 2016 Mercedes E400
    The Thule Criterium part # TH598 will work for both of your vehicles but will require you use the adapter part # Xadapt8 as long as your Mercedes bars have built in channels on top of them. Otherwise the easiest solution would be the Thule ProRide part # TH598004 which is a similar frame mounted bike rack that would fit both without the use of an adapter.

  • How To Mount Thule Ski Carrier 597/598 To New Thule WingBar Evo Crossbars
    I have a different option for you, but the adapter kit # 7533998 you were looking at will not work with your Thule Ski Carrier 597/598. Instead to mount them to your Thule WingBar Evo Crossbars you will need to use the Thule adapter # Xadapt8 which will fit your Ski Carrier, and will allow it to be installed in the tracks in your new crossbars. I included a video of the # Xadapt8 for you to take a look at.
