Positioned within the SRAM Eagle S100 range, this crankset emphasizes confidence and reliability. The aluminum crank arms ensure good resistance to the stresses of the terrain, while the steel chainring provides excellent durability for regular mountain biking use.

Thanks to X-Sync 2 technology, the SRAM Eagle S100 crankset ensures excellent chain retention, consistent with the performance expected from an Eagle drivetrain. It integrates perfectly into a 1x12-speed single chainring setup, with a 49mm chainline and compatibility with PowerSpline bottom brackets.

Introducing the SRAM Eagle S-Series range

An evolution of the Eagle ecosystem

The SRAM Eagle S series builds on over ten years of development in wide-range mountain bike drivetrains. It offers a simpler, clearer, and more consistent way to maintain, improve, or upgrade an Eagle drivetrain.

S100 Positioning

The S100 range represents the entry point into the Eagle S-Series universe. It emphasizes robustness, reliability and value for money, with components designed to deliver the essential Eagle performance.

A robust crankset for Eagle drivetrains

The Eagle S100 crankset is designed for cyclists looking for a durable, Eagle-compatible solution adapted to the constraints of a 1x12 speed mountain bike drivetrain.

Design

Aluminum cranks

The aluminum cranks offer a robust construction, suited to the demands of mountain biking. They provide a good level of resistance for sporty rides, technical terrain, and regular use.

Steel tray

The steel chainring improves the crankset's durability and wear resistance. It's a reliable solution for cyclists looking for a component that will last.

Direct Mount

The Direct Mount system allows for simple and efficient integration of the chainring, while ensuring good consistency with the SRAM Eagle architecture.

Single chainring transmission

The SRAM Eagle S100 crankset is designed for a 1x configuration. This architecture simplifies the drivetrain, reduces the number of components and meets current standards for modern mountain biking.

PowerSpline compatibility

This crankset is compatible with PowerSpline bottom brackets, particularly in 118/73 configuration.

Technologies

Eagle Technology

Eagle compatibility allows the S100 crankset to work within a SRAM Eagle 12-speed drivetrain, with good consistency between chain, chainring, cassette, derailleur and shifter.

X-Sync 2

The X-Sync 2 chainring is designed to offer excellent chain retention. Its specific tooth profile helps keep the chain in place, even on uneven terrain or during changes of pace.

32-tooth steel plate

The 32-tooth chainring offers versatile gearing, suitable for mountain biking on varied terrain, with a good compromise between efficiency, traction and obstacle clearance.

49 mm chain line

The 49mm chainline allows for consistent integration into a compatible Eagle mountain bike drivetrain.

Performance

Reliable chain retention

The X-Sync 2 chainring ensures good chain retention, in order to limit the risk of derailment on rough terrain.

Everyday robustness

The combination of aluminum cranks and a steel chainring results in a solid crankset, suitable for the repeated stresses of mountain biking.

Smooth and consistent transmission

Designed to work with the Eagle ecosystem, the S100 crankset contributes to a smooth, reliable and efficient power delivery.

Choice of crank lengths

The crankset is available in several crank arm lengths to suit the cyclist's body type, the type of bike, and pedaling preferences.

Compatibility

SRAM Eagle drivetrain

The SRAM Eagle S100 crankset is compatible with SRAM Eagle chains and Eagle 12-speed drivetrains.

PowerSpline enclosure

It is designed to work with a compatible PowerSpline bottom bracket, including the 118/73 standard.

Mountain bike assembly

This crankset is designed for mountain biking use, in a modern single chainring configuration.

Direct Mount Tray

The mounting of the platform is done via Direct Mount, for simple and efficient integration.
