The SRAM RED e1 Chain is SRAM’s most advanced road chain, engineered for maximum drivetrain efficiency, ultra-quiet operation, and long-term durability. Designed specifically for RED AXS systems, it utilizes SRAM’s Flattop architecture to deliver stronger construction, faster shifting, and reduced friction under load. Key Features & Benefits Flattop Chain TechnologyThe unique flat-top outer plate design increases chain strength while reducing width, resulting in quieter operation, improved durability, and enhanced drivetrain efficiency. HollowPin Construction for Weight SavingsPrecision-engineered hollow pins reduce weight without compromising structural integrity, making this chain ideal for high-performance and race-focused builds. Hard Chrome Inner Link FinishA chrome-hardened treatment on inner plates and rollers significantly improves wear resistance, extending chain life and maintaining consistent shifting performance over time. Optimized for AXS Electronic ShiftingSpecifically designed to work seamlessly with SRAM AXS cassettes and chainrings, ensuring fast, crisp, and predictable shifting under load. Reduced Friction DesignImproved plate shaping and surface treatment reduce drivetrain drag, helping riders maintain maximum power transfer efficiency. PowerLock Tool-Free InstallationIncludes SRAM’s PowerLock quick link for secure, tool-free installation and removal.
