Red E1 Flattop Bicycle Chain

Performance & Use Case
The SRAM Red E1 Flattop Chain is SRAM’s top-tier 12-speed chain for AXS road drivetrains. The Flattop profile delivers a quieter, longer-lasting chain than conventional designs, while the Red-tier construction shaves weight over the Force-tier equivalent.

Construction & Materials
Flattop profile – SRAM’s proprietary 12-speed chain shape. Red-tier construction with material removal for weight saving over Force-tier. PowerLock quick connector included for tool-free installation.

Compatibility & Variants
Compatible with SRAM AXS 12-speed road drivetrains (Red, Force, Rival). NOT compatible with standard 12-speed drivetrains – the Flattop profile requires a Flattop-compatible cassette and chainset. Available in 114-link (road) and 126-link (gravel/long-chain) lengths – select the link count that matches your drivetrain.
