The SRAM Rival E1 Flattop chain embodies the quintessence of technological evolution applied to drivetrain systems: lighter, quieter, four times more resistant to wear than conventional chains. Designed for SRAM Rival AXS 12-speed road and XPLR AXS 13-speed gravel groupsets, this 126-link chain integrates Flattop technology and Hard Chrome treatment to deliver exceptional longevity and unmatched shifting precision, regardless of terrain.

Technical Overview: Hard Chrome and Flattop for Performance

SRAM took its most robust Rival chain and lightened it without compromising strength. The Hard Chrome treatment applied to inner plates and rollers offers four times the resistance to elongation compared to standard SRAM chains, drastically extending drivetrain lifespan. Flattop technology enables a narrower chain profile, quieter operation, and increased strength. Cutouts on outer plates reduce weight (190 g for 126 links) while maintaining the structural integrity necessary for repeated efforts.

Technical Highlights

• Exclusive Flattop Technology: Unique ultra-flat link profile for a narrower chain, quieter operation, optimized shifting, and improved overall durability.
• Hard Chrome Treatment: Hard chrome finish applied to inner plates and rollers — wear and elongation resistance multiplied by 4 compared to other SRAM chains.
• Weight-Saving Cutouts: Cutouts on outer link plates to reduce weight without sacrificing strength — mass savings where every gram counts.
• PowerLock Quick Link Included: Connection system developed by SRAM engineers, tool-free, secure, and consistent for fast and reliable installation and removal.
• Extended Compatibility: Designed for SRAM Rival AXS 12-speed road and SRAM XPLR AXS 13-speed gravel — one chain for two riding disciplines.

Design and Finish

The nickel coating on outer links protects against corrosion and external contamination, ensuring reliable operation in all weather conditions. The silver color offers a classic and elegant aesthetic that integrates perfectly with SRAM AXS components. Each link has been precision-machined to ensure optimal engagement with SRAM X-Range cassettes and chainrings, allowing full exploitation of the available gearing range.

Use and Maintenance

Recommended for use with SRAM Rival AXS rear derailleurs (road) and SRAM XPLR AXS (gravel). Although Hard Chrome treatment significantly extends lifespan, regular maintenance (cleaning and lubrication) will optimize performance and longevity. The PowerLock quick link allows for easy replacement and deep cleaning. Expect approximately 190 g for the complete 126-link chain, an ideal balance between lightness and robustness for riding long and hard.
