[EX Q]: The main advantage is that the compact crankset gearing is much closer to the high cadence riding that is the current trend in modern cycling.  With a standard triple crank you have 30/42/52 chainrings, from which most people use the 42 and 30 rings.  The 30 is a little too short for most hilly rides, and basically you're spinning super fast to get up a hill.  The 42 is   a bit too small for barrelling down a hill, and the 52 is so steep that it's rarely being used.\n\nThe compact crankset has 50 and 34 tooth gears which are theoretically better for the way most cyclists ride today.  The 34 gives you short enough gearing to get up big hills but is not quite as short as the granny gear on the triple, and the 50 gives you the speed in a manageable dose.\n\nA couple things to consider, though.  In order to switch to a double compact, you need to replace a fair number of components, including the bottom bracket, cranks, rear derailleur (optional but highly recommended), front derailleur and possibly your left shifter.  You might be able to get what you want from switching out the cassette on your bike, which is of course a lot cheaper.
