Bouncing in the saddle

One more thing. Try to avoid riding in your liitle ring/big cog and big ring/ little cog combos. That's called crosschaining, and it's hard on your chain.

I'm sure you meant to write: "Try to avoid riding in your little ring/little cog and big ring/big cog combos. That's called crosschaining, and it's hard on your chain." It is called crosschaining because the chain quite literally crosses from one side over to the other.
