RED E1 Aero Disc Brake: The RED Aero disc brake features alloy hardware and a carbon lever with a sculpted, textured lever blade. It arrives with the newly updated RED calipers and all the top-end titanium bits of RED. Though the external appearance will differ (same with the weight), the braking performance should be the same.
Force E1 Aero Disc Brake: The Force Aero disc brake arrives with the same trappings of the RED but without a carbon lever. The caliper is updated and sculpted SRAM Force from the latest update.
Rival E1 Aero Disc Brake: The entry point to SRAM’s new Aero lever brake is Rival. This lever is more basic but still includes all the functionality of the Force and RED levers. The Rival Aero lever is alloy and lacks some of the extra features of the above, but should still offer the same braking performance, paired with the updated SRAM Rival sculpted caliper.
