Checkout the Utah Trikes website for photos and info about the Villager with added Schlumpf drive. Go to the Articles section and choose Villager review and also the article on the Schlumpf drive(the slight additional weight is discussed). For me the extra few ounces is a non-issue and of course the Schlumpf is physically smaller than a triple chain ring- I guess it boils down to whether you enjoy coasting whenever you come to a downgrade or having the ability to fly by all those annoying cyclists (two wheeled variety).
