Product details

The innovative, micrometric closure allows for quick and precise adjustment, while the hidden heel stabilization securely holds the foot throughout the ride. Sidi focuses on longevity by using only the best materials, and all parts are replaceable, ensuring that the RR Fast 2 Aerolight can be used for years.
