Are Adapters Available for Thule Prologue Bike Rack For Aero-Style Crossbars  

Question:

Expert Reply:

Unfortunately, the Thule Prologue bike rack, part # TH515 was designed for use with a square or round crossbar, so it wouldn't work with the Yakima JetStream crossbars. I've checked with my Thule rep, in hopes that there's an adapter available, but there is not.

So, your best alternative would be to go with a new bike rack, such as the Thule FastRide, part # TH95JV which fits round, square and elliptical crossbars up to 3-1/4 x 1-1/2 inches tall. The Yakima JetStream crossbars are 3-1/8 x 1 inch, so the Circuit would certainly be compatible with those.

Another option (assuming you already have the Yakima JetStream roof rack) would be to use your existing Yakima BaseLine, SkyLine, TimberLine, or RidgeLine roof rack towers, a set of RoundBar SL adapters, part # Y03536 and the proper length Yakima RoundBars for your vehicle. RoundBars are available in the following lengths:

• 48 Inch RoundBars, part # Y00408
• 58 Inch RoundBars, part # Y00409
• 66 Inch RoundBars, part # Y00410
• 78 Inch RoundBars, part # Y00411

If you want to go this route, I'd be happy to recommend the correct length of you'll reply with the year, make and model of your vehicle.

I've linked to a demonstration video for the Thule Circuit.
