Sssssick.  Don't tell Bob, but these make me want to move to Phoenix or Albuquerque and be a bike messenger next summer.  Finally, a crank arm length I can get my legs around.  I'm pretty sure I'm going to put these on my Surly Creamroller so I can destroy the levees of the Sacramento River.  So sick... So sick...
