SRAM S500 Eagle Chain Off the Chaaaain The S500 Eagle Chain has chrome-hardened solid pins and a chrome-plated PVD finish on both inner and outer links to add a layer of corrosion resistance that matters when you're deep in a wet Pacific Northwest loop or grinding through a dusty desert stage. Shifts stay consistent and quiet because the chamfer geometry and pin tolerances are dialed to work within the Eagle drivetrain ecosystem - not just close enough, but spec-matched. This chain works across MTB, e-MTB, and gravel builds, backed by a Power Lock connector for clean installation without a chain tool. Chrome-plated PVD inner and outer links, corrosion-resistant finish extends chain life in wet and abrasive conditions Chrome-hardened solid pinresists wear under high torque loads, keeping shift feel consistent deeper into the chain's service life Eagle Power Lock connectorfor tool-free installation and secure, reusable closure that meets Eagle drivetrain spec E-Bike approved: rated for the sustained high-torque demands of e-MTB drivetrains, no separate SKU required Eagle S-Series ecosystem compatibilityworks with all 12-speed Eagle components - SX, NX, GX, X01, and XX1 - though not compatible with T-Type Transmission SPECIFICATIONSCompatible Speed (CN)12Chain Length (Links)108, 110, 112, 114, 116, 118, 120, 122, 124, 126 links Chain Connector Power Lock Inner Link Finish Chrome plated, Chrome plated + PVD, PVDOuter Link Finish Chrome plated, Chrome plated + PVD, PVDPin Variant Solid Pin Chain Technology Eagle E-Bike Approved Yes | Sram | S500 Eagle Chain | Rainbow | With Powerlock, 126 Links
