I’ve been biking for a number of years, primarily single track XC or gravel riding. I do adventure racing, which is incredibly tough on the bikes, but am hoping to improve my bike life.
What are some of the important bike maintenance things that you all do?
Pretty much this.
But even more obviously, check tire pressure (use a tire pressure calculator), replenish sealant every few months (if using tubeless tires), and visually inspect tires.
Monitor chain wear once in a while using a chain checker gauge. (The Park Tool CC-4 and Pedro’s Chain Checker Plus Ⅱ are examples of pretty good ones.) Replace the chain before it exceeds the recommended wear limit so that it won’t cause your cassette to wear out prematurely.
