SRAM is streamlining Eagle into a clearer, easier-to-choose lineup: Eagle S‑Series. Three distinct tiers — S100, S200, and S500 — cover everything from durable entry-level performance to high-end wireless AXS, making upgrades and replacements far more straightforward. What’s new, who each tier is for, and what should you know about compatibility before you buy?

With a decade of success under its wings, Eagle has defined wide-range MTB drivetrain performance. We are proud to deliver the next step for Eagle Drivetrain, the S-Series. A simplified and refined offering of the best of Eagle Drivetrain products under one collection to make your choices easier, whether it’s upgrading your current ride or rejuvenating your already trusted drivetrain. Eagle has had the privilege of helping riders across the spectrum, from beginners to World Champions, and with our new Eagle S-Series, we continue that tradition.

To simplify decision-making for riders, there are three lines in the Eagle S-Series: Eagle S100, Eagle S200, and Eagle S500. These consolidate and build upon Eagle and Eagle AXS products, creating purpose-crafted, high-quality components with the right benefits for riders.

What replace what?
