25prs for 3 yrs is 36mo is 3/4 of a pad used a month. That depends on how much you use the pads, if you use only a front or you use front and back brakes and of course electrical braking. Jagwire is ok, I like the multicolored pads that are a bit longer, the curved pad thats all red and comes in packs of 3 or 4 suck.
