Here's a question I posted in the Commuting thread that someone suggested I post here instead and makes perfect sense
I always do a quick check of the brakes before every ride and the tire pressure a couple of times a week and that's pretty much it. But in the medium/long run is there a checkup list to follow or guidelines? Like for car maintenance, at 5000mi change the oil, 6000mi change the breaks, 7250mi change the engine etc.
Something in the line of after 250mi oil the chain, 500mi change the break pads, 1000mi upgrade the derailleur, 1500mi change bike? Of course I'm kidding here but you get the idea. Or more like each month "check x" etc. To find potential problems I need look for them before there are symptoms; but where, when and what to look for?
