i don't think the OP is claiming it to be hard. just much harder than a keeping a singlespeed or fixed gear running; which is 1000% true.

on my singlespeeds and fixed gear all i do is pump up the tires and lube the chain until something needs replacement.

my excuse, i got 3 kids... i don't have time to futz with bikes and when i do have time i'd rather use it riding drinking or sleeping.

that said i do own a roadie and it never needs maintanence but that is because most of my miles get put on the other bikes. the geared bike only comes out on nice days or when LOTS of hills are in the equation.
