The regular clamps will fit the Thule AeroBlade. My need was high, and my patience was low when I purchased my CRC system. I was unaware you could purchase or order XL clamps. That being said, I could only find one store within 200+ miles of me that had a CRC system in stock. It happened to be on my way through Billings MT, so paid for it and picked it up. I installed the system in the parking lot using the regular clamps that came with the system. I have the Aero Blades and with some "finesse" the regular clamps will fit the Aero Blades. I would recommend ordering the XL clamps as I have done. Once I get them all update you on the fit, but in a pinch, the regular clamps will work.

Trxstle offers great products and backs them up with unbelievably great customer service!

The CRC XL camp system was a perfect fit on my Thule Xsporter rack. Allowing me to mount my Trxstle CRC system. Great customer service and nice to talk to a real person who cares. Got the clamps to me before I took off for my fishing trip. Now if you could help me catch more trout!
