Whether you're looking to change up gearing options or replace worn out parts, understanding how to swap out your cassette, chain, cranks and chainrings are important skills to have.

Installing a new chain and cassette can breath life into an older drivetrain. And various cassettes allow you to adapt to the type of riding at hand -- larger gear ranges for big climbing days, smaller gears if you'll be hammering the flats.

Or maybe you want to try out a set of compact cranks, which can make spinning up steep hills far easier. Whatever the case, here are three instructional videos to get you up to speed.
