Chain technology rarely gets exciting until something genuinely changes. The XXSL Eagle T-Type Powerlock Chain represents SRAM's complete rethinking of how a chain interfaces with their top-tier mountain drivetrain, moving from the traditional quick-link closure to an integrated Powerlock system that seats directly into the T-Type cassette and chainring. The Powerlock isn't just a different connector—it's part of how SRAM achieves the precise chain path that makes T-Type shifting work.

The chain itself uses hollow pin construction throughout, removing material from every pin in the 126-link length. SRAM machines the inner and outer plates from hardened steel, then applies their hard chrome surface treatment to the entire chain for corrosion resistance and reduced friction. The Flattop design carries over from previous Eagle chains, using a wider inner plate geometry that increases the contact patch with cassette and chainring teeth while reducing overall chain weight.

T-Type compatibility matters here. This chain works exclusively with SRAM's Eagle T-Type ecosystem—the XX, XO, and GX T-Type cassettes paired with T-Type cranksets. The Powerlock system won't interface correctly with standard Eagle cassettes or chainrings. If you're running the previous generation Eagle drivetrain, stick with the standard XXSL Eagle chain with a traditional quick-link.... Read More
