I am into installing a couple of Ortlieb Office Bag panniers (http://www.ortlieb.com/_prod.php?lan...dukt=officebag) on a Pletscher Athlete 2-B rack (http://www.pletscher.ch/products/pdf/Athlete_2B.pdf). In other words, I won't load my bike panniers heavily but office stuff, including a laptop. I want these panniers on a minimalist rack. Will my heels hit on the bags due to the small size of the rack? Is the Topeak Explorer Tubular Rack http://www.topeak.com/products/detail/73) an option?
