Bielas SRAM Eagle S100 Powerspline

The SRAM Eagle S100 Powerspline crankset is part of the new SRAM S100 series. This groupset is designed with a focus on durability and a good price-quality ratio. It is SRAM's entry-level series for a reliable system with an expanded gear range. SRAM keeps the groupset simple but it offers everything you need. Due to the focus on robustness, the S100 series is also suitable for use on electric mountain bikes.

With its robust aluminium construction and steel X-Sync 2 chainring, the SRAM Eagle S100 crankset makes for direct power transfer. Full compatibility with the Eagle Drivetrain Ecosystem makes it quite versatile. The crankset is compatible with PowerSpline bottom brackets, with a recommended size of 118/73 mm.

Materials and construction
The SRAM Eagle S100 crankset has sturdy aluminium crank arms that offer an excellent balance between strength and weight. This construction provides a reliable foundation that can withstand intensive use. The crankset is fitted with a steel 3-bolt X-Sync 2 chainring, which is compatible with the Eagle Ecosystem. Thanks to the combination of aluminium crank arms and a steel wear part, the whole unit is lightweight and the chainring has a very long service life. The chainring’s X-Sync 2 technology keeps the chain on the chainring just as effectively as all other Eagle drivetrains.

- 118/73 PowerSpline bottom brackets
- Eagle 12-speed drivetrains
- Direct Mount 3-bolt chainring interface
