Bungee cord for bike rack?

[Possegal]

I have a Saris Bones, too. I like to make sure the rear wheel can't turn so I will know that the pedal won't move and contact my paint job.

Me too. I use something similar for both wheels, and darn if I can find it online to share. They are bendable and sort of twist-tie around the wheels. That way there is no hook to deal with, so nothing to fail and go flying off the bike. That was my worry with the bungee cords. I'll keep looking if I can find them online.
