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.

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. 465917

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! 652012

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. 296659

I used this adapter kit to mount Thule SUP Taxi to my Thule TracRac - TracOne racks. The original SUP Taxi mount-straps were not long to fit these racks, even though the buyers guide indicates they are. This adapter kit made it possible to secure the SUP taxi right to the bar. So glad you had this available! Now I'm ready for our trip to the FL Keys! 649238

Needed this to adapt a Rocky Mounts Driveshaft rack from my old truck to the new one. These fit perfectly in the channel on the 2019 Ram's 'sport utility bar', which is a Thule 393. A little more bolt length than I needed but the extra is not hurting anything... 583216

Hats off to etrailer for carrying and timely delivery to get parts for things I need. I had these bicycle racks for a while and lost two of the adapters in a move. I couldn't even figure out how to get them from the dealer / manufacturer, but with etrailer it was easy. They are my "go to" source for parts when it comes to trailers parts and accessories. Thanks! 430690

These bolts solved the issue when there was limited thread engagement on original bolts assembling hullaport kayak carriers on aeroblade bars. I've made many trips to the water without needing to worry a nut might vibrate off. Fits nicely, performs well. Would have been hard to find elsewhere. 391872

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. 161538

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! 252094

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. 524185

The Thule Bike Rack Adaptor to go from square bars to aero cross bars was an easy purchase. Otherwise, I would have had to two new bike racks. It saved me a lot of money! etrailer.com was a great place to buy the needed parts, and they were quick with shipping them to me. I watched their video on the installation, and within an hour, both racks were installed and ready to go. Thanks etrailer.com for easy transaction. 273723

I used the adapter to fit a Thule Peloton bike carrier (previously used with square Thule load bars) to the factory roof rack on our Mini Clubman. The adapter works out well in this application; the only thing to note is that re-using the round-head bolts that came with the Peloton carrier with the thick vinyl-coated bracket in this adapter kit results in VERY little room to fit the nuts that hold the bracket on -- it just about works, and seems to do so safely, but it is a very tight fit. 420303

Thule XADAPT2 AeroBlade and Xsporter Load Bar Adapter for Roof-Mounted Carriers This kit solved the problem of attaching a new Thule Big Mouth Upright bike rack to an existing Thule Aero bar. All the parts and pieces fit together in what is a truly elegant design to mate the bike rack to the bar without having to upgrade to a new bar costing $200.00, so the added benefit is a significant cost saving.

  • 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.

  • 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...

  • Roof Rack and Bike Rack Recommendation for a 2007 Saturn Ion
  • For your 2007 Saturn Ion the Inno Roof Rack part numbers # INXB138-2, # INXS250, and # INK214 has been confirmed as a fit. To use the Thule # TH526XT on this rack will require the use of the # Xadapt8 as well so that it will fit the T-slot of the cross bars. This rack will have a 28 inch crossbar spread which is also compatible with the Thule bike rack.

  • 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...

  • 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...

  • 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.

  • 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.

  • 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...
