Bungee cord for bike rack?

[HillSlugger]

Thanks for the ideas, and I didn't think what that spinning might do to the mileage on my nice new Cateye Strada computer My bike rack is the Saris Bones RS, and I have not noticed the rear wheel spinning, only the front. Tomorrow will likely be my last opportunity to go anywhere with my bike until at least the end of the week, so if I don't have a chance tomorrow to find some way to secure that front wheel, I certainly will have done so by next weekend.

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.
