Product details

The RR Fast 2 Aerolight by Sidi is a highly developed cycling shoe designed for demanding cyclists. With its proven durability and excellent grip, it offers both comfort and performance. The shoe's sole is aerodynamically designed and combines nylon and carbon fibers to ensure a balanced ratio of stiffness and flexibility, supported by a stiffness index of 5. The fit is the result of over 60 years of experience in developing cycling shoes, meaning the shoe fits optimally and adapts to the shape of the foot. The innovative micrometric closure allows for quick and precise adjustments, while the soft upper material provides a pleasant wearing experience. Additionally, the hidden heel stabilization ensures that the foot is securely held throughout the ride. The RR Fast 2 Aerolight is not only known for its performance but also for its durability, as all parts are replaceable and the best materials are used.

  • Aerodynamic sole for optimal comfort and performance
  • Micrometric closure for precise adjustment
  • Soft upper material for outstanding comfort
  • Hidden heel stabilization for secure hold
  • Replaceable parts for long-term use.
