Product details

The RR Fast 2 Aerolight from 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 adaptive closure allows for quick and precise adjustments, while the hidden heel stabilization keeps the foot secure throughout the ride. Sidi focuses on longevity by using only the best materials and ensuring that all parts are replaceable, allowing the shoe to be used for years.
