The compact crankset

The compact crankset has two chainrings as opposed to a three chainring triple crankset. Typical ratios are 34/48, 34/50 and 36/50. This provides nearly the same lower gear ratios as a triple but without the need for a third chainring, a triple front derailleur and a long cage rear derailleur. Manufactures recommend and sell front derailleurs specifically designed for compact cranksets claiming better shifting.
