SRAM RED E1 Chain

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 Technology
The 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 Savings
Precision-engineered hollow pins reduce weight without compromising structural integrity, making this chain ideal for high-performance and race-focused builds.

Hard Chrome Inner Link Finish
A 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 Shifting
Specifically designed to work seamlessly with SRAM AXS cassettes and chainrings, ensuring fast, crisp, and predictable shifting under load.

Reduced Friction Design
Improved plate shaping and surface treatment reduce drivetrain drag, helping riders maintain maximum power transfer efficiency.

PowerLock Tool-Free Installation
Includes SRAM’s PowerLock quick link for secure, tool-free installation and removal.
