Flattop Technology – Revolutionary narrower chain design delivers quieter operation, increased strength, and exceptional durability for race-winning performance
Ultra-Lightweight Construction – Super-light outer plates with cut-out design and HollowPin construction save 13g over the previous RED chain without compromising strength
Hard Chrome Plated Components – Chrome-plated inner link plates and rollers provide reduced wear and significantly prolonged chain life
HollowPin Engineering – Advanced hollow pin construction delivers increased strength and efficiency while reducing weight for optimal power transfer
PowerLock D1 Connector – Secure, tool-free PowerLock D1 connector designed specifically for Flattop chains ensures easy installation and reliable connection
We took the lightest and most durable chain we’ve ever made and made it lighter. With no compromises. Our HollowPin construction is lighter and stronger than a solid pin, and cutouts in the outer and inner plates drop 13 g from the previous generation. Can a chain really be lighter, faster, stronger and more durable than anything else? This one is.

FAQ
Q: What is Flattop technology and why is it different? A: Flattop is SRAM's revolutionary chain design with a flat-topped profile instead of traditional rounded outer plates. This allows for a narrower chain that runs quieter, shifts more smoothly, and is actually stronger and more durable than conventional chains despite being lighter.
Q: Will this chain work with my 12-speed drivetrain? A: This chain is specifically designed for SRAM RED eTap AXS and Force eTap AXS 12-speed road drivetrains. It will NOT work with Shimano, Campagnolo, or SRAM Eagle mountain bike 12-speed systems due to the unique Flattop design and spacing requirements.
Q: How is this chain 13g lighter than the previous RED chain? A: Weight savings come from the super-light outer plates with cut-out design and advanced HollowPin construction. Despite being lighter, it's actually stronger and more durable thanks to the Flattop technology and hard chrome plating on critical wear surfaces.
Q: How many links do I need - 114 or 126? A: Road bikes typically use 114 links for standard setups. The 126-link option is for bikes with longer chainstays, larger cassettes, or specific frame geometries. Measure your old chain or consult SRAM's sizing guide for your specific setup.
Q: Can I use a standard PowerLock connector with this chain? A: No, you must use the PowerLock D1 connector that's specifically designed for Flattop chains. Standard PowerLock connectors won't work with the unique Flattop profile. The correct PowerLock D1 is included with the chain.
