Thule Ride-On Rooftop Bike Rack Adapter

Factory installed roof racks typically have larger load bars (those that run from the driver's to passenger's side of the vehicle). The Ride-On adapter has extra wide mounts so that it can be clamped to the larger load bars. The adapter then provides Thule standard load bars that allow for easy attachment of Thule roof mounted bike racks.

Create more bike carrying options for your vehicle with a bike rack adapter that fits factory installed roof racks, whether on your car, van, or SUV. The versatile design of the Ride-On provides a stable and secure load carrying system to support a roof mounted bike rack as well as enabling almost any bike carrier to be installed to the existing load bars on your vehicle.

Video Transcript for Thule Ride-On Adapter Review

Today we are going to cover part number TH532 from Thule. This is Thules Ride-On Adapter, and what this device basically does is, it converts your existing roof rack from the factory to be able to use a variety of different Thule products on your roof rack. Basically, what this adapter does it, it actually stacks on top of your existing crossbar. This has to have the factory rack. It also has the bars going from left to right. It also comes with a special torque bit, here. This actually has a security bit that actually has a hollow point so not a regular torques bit can get in there and undo it, so you have a level of security built in right there. Now I will go ahead and just put this on a factory roof rack and give you a better idea of how it looks and how it works.

All right, let us go ahead and install one of the adapter bars. It is pretty simple. Get it on top of your factory roof rack crossbar here and get it even. And you simply take one of the clamps and put it on the bottom and screw it into place. All right, and with that your roof rack is ready to go with virtually any Thule accessory out there. And there you have it for part number TH532 from Thule.

The existing Thule rack was still serving the purpose, but after being transferred across 3 vehicles and almost 20 years of service, was showing it's age (i.e. sun-faded plastics, and surface rust on the square bars) For a terrific price and a 2-day wait, I now have the exact same rack setup...ready for another 20. 370530

  • How to Install Thule ProRide on Factory Crossbars on 2006 Subaru Forester
  • Thule's ProRide, part # TH598003 will fit to your factory crossbar without needing to use the Thule Ride On, part # TH532. For example, if you prefer a fork-mount carrier that includes locks an excellent choice is the Rhino-Rack MountainTrail # RBC035.

  • Roof Rack Adapter to Allow Installation of Yakima Sidewinder Bike Rack on Subaru Factory Bars
  • The Yakima Sidewinder Roof Tandem Bike Rack # Y02071 is designed to fit on round or square crossbars that are spaced between 24- and 36-inches apart. It will not directly fit on your Subaru factory bars and Yakima's Universal Might Mount Adapters # Y03590 are not compatible with the carrier. I do have another option for you. The best solution I can recommend is to use Thule's Ride-On Adapter # TH532. This is essentially a small roof rack with square bars that attaches to your factory...

  • Available Adapter to Fit Older Yakima Roof Mount Bike Racks on a 2016 Ford Explorer w/ Factory Bars
  • The Thule Ride-On Adapter, # TH532, can allow you to attach your Yakima Viper rack to your vehicle if this bike rack can be mounted to square crossbars. However, if the SteelHead rack can only be mounted to round bars, then that rack cannot be mounted to the Thule Ride-On. I contacted Yakima to see if they offered an adaptor that will allow the Viper and SteelHead bike racks to attach to the factory crossbars of the 2016 Ford Explorer. Unfortunately, they told me that there is no adapter...

  • How to Fit Older Thule Mountaineer on a 2016 Honda Pilot Factory Crossbars
  • Are you missing the hardware for your Mountaineer? Or is the factory hardware just not fitting around the crossbars? If it won't fit there's really nothing I can safely recommend that would adapt the box aside from the Ride On Adapter part # TH532 which would fit your bars and then give the box square bars to attach to. If the Mountaineer cargo box you have is an ES model (669ES) then # 05704 will fit. For older Mountaineer boxes, the correct replacement hardware is # TH04997.

  • Can Older Thule Bike Carriers Be Used on Thule AeroBlade Load Bars on a 2017 Subaru Forester
  • The Thule Ride-On Adapter, # TH532, can mount to the Thule AeroBlade crossbars and then allow you to attach your older Thule bike rack. The adapter has square load bars and has a two bike rack capacity. The Ride-On adapter is compatible with the following Thule bike racks: Thule Criterium Thule Big Mouth Thule Echelon Thule Peloton Thule Peloton Long Tray Thule Prologue However, the adapter will not work with the Thule Sidearm, Tandem Carrier, or the Thule Super G.

  • Adapting a Thule BigMouth to Factory AeroStyle Bars
  • I have a solution for you, but at this time, there isn't a clamp kit that replaces the original mounting gear on the Thule BigMouth. Instead, I recommend the Thule Ride-On Adapter, part # TH532. This provides a smaller square bar that clamps onto your existing roof rack bars and allows you to mount the BigMouth's directly to that. Because of the quick-release nature of the bars, they're easy to remove after a ride. If you'd rather outright replace the racks instead of having the...

  • Adapter Availability for Thule Adventurer to Fit Wider Crossbars

  • Adapter Kit for a Thule ProRide to Fit Factory Bars on a 2005 Nissan Xterra
  • The Thule ProRide, part # TH598003, according to Thule, is not a confirmed fit for the 2005 Nissan Xterra. You can, however, use a Thule Ride-On Adapter, part # TH532 to add a secondary rack to your system and provides compatible bars for the Thule ProRide. If you'd rather have a natively fitting carrier, I recommend the Thule Sidearm, part #TH594XT. This rack has many of the same features as the ProRide, but allows for more crossbar types to be used, and is a Thule confirmed fit...

  • 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...

  • Will Old Honda Branded Thule Bike Rack Fit Crossbars on a 2017 Subaru Outback Wagon
  • While I do believe you are correct about the Honda bike rack being a Thule in disguise the mounting hardware # TH7533263 won't work because it will not fit the crossbars on your 2017 Subaru Outback. It is designed for Thule square bars that are 1-1/4 inches wide. In order to use the rack you have you would need this hardware kit and the Ride-On adapter # TH532. You could go with a new bike rack that is a direct fit such as the ProRide # TH598003 or the Sidearm # TH594XT.

  • Using Thule Hullavator Pro Kayak Carrier on 2016 Subaru Outback Wagon with Factory Crossbars
  • I do have a solution for you, however the Thule Ride-On Adapter # TH532 referenced in your question is designed to support 2 bike carriers and simply does not have the required capacity or size to mount and operate the Thule Hullavator Pro Kayak Carrier # TH898. I instead recommend installing the Thule Roof Rack, which consists of # THARB47 for the crossbars, # TH460R for the foot pack and # THKIT4063 for the fit kit. This system is confirmed to fit your 2016 Subaru Outback Wagon with...

  • Mounting Bike Racks for Square Roof Rack Bars to a 2013 Honda CR-V with Factory Roof Rack
  • The easiest and least expensive solution is to use the Thule Ride-On adapter # TH532. It will fit the factory crossbars on your 2013 Honda CR-V and the bike racks will fit the Thule square bars. The aftermarket roof racks for the CR-V will cost at least 4 or 5 times as much as the Ride-On adapter and may not even work properly if the vehicle has factory crossbars. The Ride-On adapter is the way to go. Another possible option is to use an adapter for the bike racks themselves. To see...

  • We can help you with a roof rack for your 2010 Ford Flex to allow installation of your X Cargo rooftop carrier. If your Flex has raised front-to-back side rails on the roof then a good rack choice for the cargo box is the square bar Thule Crossroads system made of parts # THLB58 and # TH450. Square bar racks generally offer very good compatibility with the available roof-mount accessories products like cargo and bike carriers. This rack will install with a bar spread of 50-inches and...

  • Recommended Roof Mounted Bike Rack for 2010 Subaru Outback with Wagon Factory Crossbars

This bike rack also holds onto the bike frame for a snug fit and is covered by Thule's limited lifetime warranty. This bike rack can carry up to 50 lbs. with a wheel capacity of 20" to 29" in diameter. I attached a review video of the Thule Sidearm you may want to check out.

  • How to Install Tandem Roof Bike Rack on Thule Aero Crossbar Roof Rack

  • Is the Thule TH532 adapter Compatable to use with RKY0512 and if needed the RKY0513
  • The Thule Ride-On Adapter, # TH532, will mount to a cross bar that is 3 inches in width like the bars on your 2013 Hyundai Santa Fe. The Thule Ride-On Adapter will fit the Rocky Mounts Carrier # RKY0512. However the Thule bars are 32 inches in length. This may be an issue in that the bars man not be long enough to allow you enough room to mount the carrier and to install the bike on the carrier. The kit that you referenced is no longer available. Therefore, you might have to replace...

  • Will Thule Ride On Adapter TH532 Fit a 2016 Honda CR-V

  • What Adapter Needed to Install Thule Criterium Bike Rack TH598 on 1991 Jeep Cherokee Roof Rack
  • Thule part TH598 is for their roof-mount Criterium frame-mount bike carrier. This carrier is designed to fit only Thule square bars or Yakima round bars. So to mount this on a vehicle that has a factory-installed roof rack you'll just need to add on the Thule Ride-On Adapter # TH532. The Ride-On Adapter will mount to any factory or aftermarket bars that are up to 3-1/2-inches wide x 1-1/2-inches tall. Your Criterium bike rack can then mount to the square bars included with the adapter. Here...

  • Thule Roof Rack Adapter fro AeroBlade Crossbars
  • If you do not want to use the Yakima Universal Mighty Mount kit # Y03590 on your Thule AeroBlade cross bars you might prefer the Thule Ride-On Adapter # TH532 which fits on roof rack bars up to 3-1/2-inches wide x 1-1/2-inches tall. Since AeroBlade bars measure 3-1/8 wide x 1-1/8 tall the Ride-On adapter will fit. The adapter then provides basic square bars that will accept a wide range of rack-mount bike carriers so long as they fit square bars.

  • Recommended Roof Rack That Can Work With A Kayak Carrier For 2004 Mazda Tribute
  • Rhe Thule Ride-On Adapter, part # TH532 will only work with bike carriers. This adapter uses plastic mounting hardware and cannot handle the stress a kayak would have and would fail. You will need to either install a roof rack designed to be able to handle the weight and stress, or if you have crossbars already on your Tribute you can find a kayak carrier that will fit your crossbars. If you do not have a kayak carrier and you have factory crossbars on your Tribute, the # TH532...

  • Will Thule Universal Ski Hardware Fit 2006 Chrysler Pacifica Factory Roof Rack and Big Mouth Racks
  • The Thule universal ski rack hardware # 7533998 will fit bars that are up to 3-3/4 inches wide. If the bars on your 2006 Chrysler Pacifica are in that range then the hardware will fit. But they are not a fit for the older Thule Big Mouth bike racks but I do have a solution for you. In order to use the older Big Mouth bike racks that you have you will need to use the Thule Ride-on adapter # TH532. It mounts to the factory crossbars on your Pacifica and the bikes will mount to the adapter.

  • Recommended Adapter For Roof Mount Bike Carrier For 2014 Lexus RX 450h
  • The adapter that we offer that will work with your factory crossbars on your RX 450h is the Thule Ride-On Adapter, part # TH532. This adapter clamps on to the factory crossbars and you then have Thule square crossbars that the Echelon bike carrier is designed to fit. It does wind up giving you double crossbars which may not be really appealing or attractive and will also mean the bike is that much higher on the roof. There is no adapter that allows the mounting hardware to fit directly...

  • Is the Thule Ride-On Adapter Required to Mount Sidearm Bike Racks on a 2015 GMC Yukon XL Roof Rack
  • I checked with Thule and the Sidearm # TH594XT is a direct fit to the factory crossbars on the 2015 GMC Yukon XL. So if you already have the XT version or plan on buying a couple of them they will fit without needing the Ride-On adapter # TH532. If you have the older version of the Sidearm that only fits square bars (594) then it is not compatible with the Ride-On adapter because it would not be stable enough with that particular bike rack along with a few others. Also it will be...
