SRAM Flattop Technology

The distinctive Flattop profile creates a narrower chain while improving strength and durability. The unique shape also contributes to quieter running and more consistent shifting performance across the cassette.

HollowPin Construction

Precisely engineered hollow pins reduce overall mass without sacrificing structural integrity. The result is a lighter drivetrain component capable of handling professional-level power output and sprint forces.

Hard Chrome Wear Protection

The rollers and inner plates receive advanced hard chrome treatment to reduce friction and significantly slow wear. This helps maintain smooth shifting for longer intervals between chain replacements.

Optimised Plate Design

Both inner and outer plates feature extensive machining and cut-outs to reduce weight while maintaining durability. SRAM removed approximately 13 grams from the previous RED chain generation.

The SRAM RED E1 Flattop Chain is ideal for competitive road cyclists, endurance riders, gran fondo participants and performance enthusiasts who want the lowest possible drivetrain weight without compromising reliability.

SRAM provides warranty coverage against manufacturing defects in materials and workmanship.

When the latest SRAM RED AXS platform launched in May 2024, several independent cycling publications highlighted the drivetrain's reduced weight, improved refinement and enhanced efficiency. Reviews from Cyclist, Road.cc and Gran Fondo noted SRAM's focus on making every component lighter and more user-friendly while maintaining elite-level performance. The new RED chain was specifically recognised as part of SRAM's broader effort to reduce overall groupset weight without sacrificing durability or shifting performance (Cyclist Review, May 2024; Road.cc Review, May 2024; Gran Fondo Magazine Review, May 2024).
