Adapter Needed to Fit Thule Prologue Pack 515 Bike Rack to Rhino-Rack Vortex Crossbars


I have a set of old Thule rooftop bike racks. About 20 years old Don’t know the model # but two of them are fork style that mount on the square bar directly and the third takes the full bike with a support bar and flange that mounts in the front square bar. All 3 are held to the rear square bare by a t slot and bolts on the bottom of the bike rack. All 3 also have the number 515 on them. I recently purchased a rhino set of bars vortex va and need an adapter kit for all 3 bike racks. Any help will be much appreciated

Thank you for the details and the picture! There used to be an adapter that could be used but that has also been discontinued. At this time you either need new square crossbars or a new bike rack that can mount directly to aero-style crossbars.

If you decide to go this route and you want to stick with the Thule brand then you need the Thule FastRide # TH95JV. for something more cost-effective I recommend the Inno Fork Lock III # INA391 instead. Review videos of each have been added for you to check out.
