Thats not possiable, when there bikes explode they'll feel stupid, my bike gets completely stripped down every other week, sometimes every week. If i've done anything that involves dirt, grit or sand it gets taken apart cleaned and re greased. And i replace parts usually months before they wear out Especially chains and tyres, although i like worn grips but thats just me. If it aint broke, take it apart and have a look so you know what to do if it does brake.
