What is the SRAM Eagle S100 Chain built for?

The SRAM Eagle S100 Chain is the entry point into SRAM's redesigned Eagle Transmission chain lineup, built specifically for the Eagle Drivetrain Ecosystem and compatible with every modern 12-speed Eagle setup. It uses solid pin construction for durability under load and ships with a PowerLock quick connector for tool-free installation. No fancy finishes here, just a reliable, no-nonsense 126-link chain that handles the demands of trail riding day in and day out.

The S100 is also e-bike approved, so it holds up to the higher torque loads of pedal-assist drivetrains without giving up shift quality. It skips the nickel and black oxide finishes the S200 carries, which is the real difference between the two. If you run an Eagle 12-speed drivetrain and want a clean replacement that matches OE spec, this is the one to keep on the shelf.
