There is no need for $500 wheel chocks. A set of good quality ratcheting straps tying down the wheels correctly works fine, is the BRP preferred method, does not damage wheels, alignment or any suspension component. I have hauled vehicles FAR in excess of 10x the value of spyders many thousands of miles using ratchet straps through the wheels and never once damaged a wheel or suspension component. The wheels and thier attachment are what supports all forces on the bike during normal road use, they are the only parts designed to do so and are what should be used during transport.

Mike's suggestion of an over the tire use of the strap is a good one and works well on trailers that have access directly in line with the tires. Many trailers do not.

Sorry to say, superclamps are a well built solution looking for a problem that does not exist.
