If you look after your components then they will last a long time.
I check to make sure the bolts are tight on everything once a month. If the crank arms are fitted correctly they can't really wear out too fast. All cranks fatigue quickly if something is loose on them.
I have never had any trouble with mine on that front.
thanks andy. i always check all the nuts and bolts on my bikes once a month as well, so i think i'll give them a go.
