They never announced their reasons for withdrawing their "Pitch 10" chains, cranksets, etc., from the market, but Shimano probably had few customers willing to risk buying components that were so absolutely incompatible with the universal standard of 12.5 mm chain pitch, despite the claimed 10% reduction in weight compared to standard chains, derailleurs, freewheels, and cranksets. Pitch 10 components did appear on track bikes for a while, but I don't remember seeing or hearing of any bike manufacturer offering a multispeed bike equipped with a Pitch 10 system.
