SRAM Eagle S100 are robust mountain cranks with aluminum arms and a steel X-Sync 2 chainring that provide reliable power transfer and secure chain guidance within the 12-speed Eagle system. Thanks to the progressively shorter available lengths, they allow you to build a bike without compromise, whether it's for trail, enduro or recreational riding.

The three-bolt chainring mount ensures full compatibility with the Eagle Drivetrain ecosystem and easy chainring swapping according to terrain and riding style. The cranks are designed for the Powerspline 118/73 bottom bracket and represent an affordable solution with an emphasis on durability and longevity.

  • Aluminum crank arms for reliable and durable power transmission
  • X-Sync 2 steel chainring with excellent chain guidance in the Eagle system
  • Three-bolt chainring mount compatible with Eagle Drivetrain
  • Multiple crank lengths available for optimal rider fit
  • Designed for Powerspline 118/73 bottom bracket
  • Suitable for 1x Eagle drive with wide gear range

SRAM
1-chainring SRAM
Sram, founded in 1987 in the USA, has brought many revolutionary solutions through the years. While the brand flourished, they took other brands under their wings, such as Sachs, Rock Shox, Avid, Truvativ, Zipp or Quarq. At the beginning of the new millennium, Sram focused on components for road cycling while beating concurrence with electronic wireless switching.
