After already suffering from some major scuffs and dings on the my Truvativ Noir cranks, I was happy to accept sponsorship from Crankskins. They make high quality protection for crankarms and chainstays. I also really like the ability to personalize your bike through the different patterns and colors. Haven't gotten mine yet, but will soon. Need to figure out what colors I want! Visit http://www.crankskins.com/ for more information.
