The Tecno-4 Iron is a closure mechanism developed by SIDI for its high-performance cycling shoes. It represents the latest evolution in SIDI’s dial-based systems, offering enhanced ergonomics, adjustability, and durability.
- The Tecno-4 dial lifts away from the shoe tongue, creating more space for the foot to slide in easily
- The rotor has been redesigned to be lighter and quicker to operate than previous Tecno systems
- The central mechanism balances tension across the shoe, adapting to various instep shapes for a secure and comfortable fit
