"maintenance free" only means that it will work, until it doesn't. Once that happens, it is time to look into rebuild options that the manufacturer never thought necessary. It may also be possible that the bike manufacturer misrepresented the component manufacturer's specs thinking that nobody would ride that bike as far as you have.
