Chainrings cater to different types of bikes: road bikes, mountain bikes, and gravel, with gravel bikes typically using either road or mountain chainrings depending on the drivetrain. Larger chainrings provide higher speeds but make climbing harder, while smaller chainrings make ascending easier but limit your speed on descents.
