Taking good care of your bike is important matter. I am no mechanic, but I learned how to do some important maintenance steps to keep my ride going.

Disc brakes, suspension forks and shocks need almost constant attention to deliver smooth performance. Plus there is nothing more annoying than a rubbing brake, a squeaking suspension or a skipping derailleur to ruin your day.
The starting point is a good book of bike maintenance. I recommend: “Zinn and the art of mountain bike maintenance”, available at any book store or thru Amazon.com
You can also find a lot of good info on Park Tools web site about how to cure your bike.
