The GX Eagle Transmission (T-Type) chain is the strongest we have ever made. Specifically engineered to optimize Eagle Transmission, this all-new T-Type design features a unique flat top.
It might look normal from the outside, but the engineering inside this incredible chain design makes possible a gear range previously found only in 2-chainring drivetrains.
The XX1 chain represents the latest breakthrough in a long line of precise, light weight chains from SRAM. Its designed to deliver the greatest strength.
Designed for use with our proven, reliable XD™ driver body, this 12-speed, cassette offers an optimal 520-percent gear range. In independent tests the X-Dome™ architecture is proven to yield the strongest cassette on the market.
