SRAM GX Eagle 12-Speed Chain – 126 Links with PowerLock & FLOW LINK™

The SRAM GX Eagle 12-speed chain is built to deliver one of the best balances of durability, shifting performance, and value in the Eagle drivetrain range.

Designed specifically around SRAM’s Eagle geometry, this chain is engineered to work across all Eagle 12-speed drivetrains—providing smooth, reliable shifting under load while improving long-term wear on both cassettes and chainrings. SRAM designed Eagle as a complete system, and the GX chain sits right in the sweet spot for riders who want proper performance without moving into premium XX1 pricing.

A major feature is the use of Eagle PowerLock® with FLOW LINK™ technology, which improves chain guiding, reduces friction, and increases longevity. The redesigned inner plates help the chain run more efficiently across wide-range Eagle cassettes while also improving wear resistance over time.

This version uses solid chrome-hardened pins, with a nickel outer link finish and black oxide inner links for corrosion resistance and long-term reliability. It is also officially E-Bike Approved, making it a strong choice for modern eMTBs where torque loads are significantly higher.

With 126 links, it covers the majority of modern trail, enduro, and eMTB setups and includes the PowerLock connector for secure installation.

This is the chain most riders should be running—strong, dependable, and proven.

Torque Collective Insight

This is the chain we’d recommend for most riders.

There are cheaper chains.
There are lighter chains.

But GX is where performance, durability, and sensible pricing meet.

For eMTB riders especially, that matters.

You need:

• strong wear resistance
• reliable shifting under load
• a chain that won’t get destroyed by motor torque

The GX Eagle chain consistently delivers that.

It’s also one of the easiest upsells in workshop servicing because riders genuinely notice the difference between a worn cheap chain and a properly matched Eagle chain.

If you’re running:

• GX
• X01
• XX1
• mechanical Eagle
• AXS Eagle

…this is often the smartest replacement choice.

It’s the “fit it and ride” option.

Important Note

This is for standard Eagle 12-speed systems, not T-Type Transmission.

If you are running:

• GX Transmission

• XX Transmission

…you need the newer T-Type flat-top chain, not this version.
