long hat

The long cage allows the derailleur to handle a wide-range cassette, with a maximum tooth size of 50 teeth.

Sturdy construction

The steel cage and the pulleys with steel bearings enhance the durability of the derailleur and its ability to withstand the stresses of mountain biking.

Configuration 1x

The derailleur is designed for single chainring drivetrains, in order to offer a simple, efficient drivetrain adapted to modern mountain biking practices.

Technologies

X-Actuation

X-Actuation technology is designed to work with SRAM Eagle shifters. It ensures optimal cable pull for the drivetrain and allows for precise shifting across the entire cassette range.

Eagle Technology

Eagle technology allows you to enjoy a wide-range 12-speed mountain bike drivetrain, designed to offer good pedaling efficiency, great versatility and compatibility within the SRAM Eagle ecosystem.

Drag Spring C-arm Damper

The Drag Spring damper integrated into the chain guide helps keep the chain in place on rough terrain. It contributes to quieter, more stable, and more reliable operation.

Half Mount Compatibility

The mounting screw is Half Mount compatible. Combined with a UDH hanger and a Half Mount plate, this system reinforces the derailleur hanger's security and improves its resistance to accidental impacts.

Performance

Precise gear changes

The SRAM Eagle S100 is designed to offer precise and consistent gear changes, even under stress and in demanding conditions.

Maximum range of 500%

The derailleur can operate with a maximum gear range of 500%, particularly when used with a SRAM PG-1210 cassette.

High-stress application

The S100 derailleur is designed to excel in high-torque applications, making it suitable for intense efforts, technical climbs, and demanding riding.

Secure chain retention

Thanks to the Drag Spring damper, the derailleur helps to keep the chain under tension and limit excessive movement on uneven terrain.

Compatibility

Eagle 12-speed transmission

The SRAM Eagle S100 derailleur is designed for Eagle 12-speed drivetrains.

Eagle controls

Thanks to the X-Actuation pull, it is compatible with SRAM Eagle shifters designed for this standard.

Cassette up to 50 teeth

The derailleur accepts a maximum of 50 teeth, with a cassette range adapted to the Eagle S100 ecosystem.

Single chainring transmission

It is designed for 1x transmissions, consistent with the modern Eagle architecture.
