Mission Workshop Vandal. Best bag ever. You pay for what you get, and what you get with the Vandal is a SUV...its epic big. I rode my Rockhopper 29er WITH my CAAD9-5 strapped to it along with the wheels AND had my college books (around another 20 pounds) and still had room for spare clothing and my lunch AND dinner. Only thing the bag didn't hold at that point was me.
