Product details

The SX-1 Eagle Boost is a highly advanced drivetrain that embodies Sram's latest 1x drivetrain technology. With Eagle technology, it offers a lighter, more robust, and user-friendly system that delivers outstanding performance and durability. The extended gear range of 500% makes this drivetrain comparable to traditional 2x11 systems, making it ideal for various applications such as marathon, cross country, and enduro. The X-SYNC 2 Eagle technology ensures improved chain tension and pedaling efficiency, while the DUB technology optimizes the integration between chainring, cranks, and bottom bracket. This results in increased stiffness and longevity of the entire system. The SX-1 Eagle Boost is therefore an excellent choice for demanding cyclists who value performance and reliability.

  • Extended gear range of 500% for versatile use
  • X-SYNC 2 technology increases chain tension and efficiency
  • DUB technology enhances stiffness and durability
  • Lightweight and robust design for optimal performance.
