What makes the SRAM GX Eagle T-Type chain different from standard Eagle?

The SRAM GX Eagle T-Type chain is engineered specifically for SRAM's T-Type drivetrain system, which uses a Flattop chain design with a unique flat-top link profile that enables more precise engagement with T-Type chainrings and cassettes. This 126-link chain is not interchangeable with standard Eagle chains and must be used with T-Type compatible components. Includes an Eagle Flattop PowerLock connecting link.

T-Type represents SRAM's next generation of Eagle drivetrain technology, delivering faster, more consistent shifting through a fundamentally different chain-to-drivetrain interface. If you're running GX Eagle T-Type components, this is the chain that makes the system work as designed. Do not mix with standard (non-T-Type) Eagle drivetrains.
