Okay, so I got my first road bike, a Trek 1500, I love it so far. I'm wondering what are the things you check before a ride? I'm guessing tire pressure, making sure the wheels are on securely... anything else? And how about after a ride, is there anything that should be done? How about lubing up the chain, how often is that done? What kind of routines do you all have before and after a ride? Thanks in advance.
