Ah, bike cassette, how beautiful you are, with your shiny cogs, stacked neatly in a row. You may be a 9-speed cassette; you may be an 8-speed cassette. Whatever your speed, we know we can rely on you to keep that rear wheel moving. You're an integral part of the bike's drivetrain, and without you, we'd be stuck in one single gear. Yes, this point and click is for you, lovely bike cassette.
