I recently designed some banners for ROL Wheels. This is a solid company specializing in road bike wheels and their customer service is second to none!
They've got carbon fiber wheels and all kinds of high tech wheelsets if you're into road biking.
Okay, this wasn't meant to be a plug, but I guess now it is :P
I should note that ROL was voted "Best Of Roadbike Review" three years in a row - in a different category each time! And since I bike to work everyday, this was an especially cool project.
I like designing banners. Especially animated ones!
