Sidi Shot/Tiger Double Tecno-3 Push Closure System Description: The Sidi Shot/Tiger Double Tecno-3 Push Closure System is a factory spec'd OEM replacement closure mechanism for the Sidi Shot 2S road shoes and the Sidi Tiger 2S mountain bike shoes. This shoe retention system utilizes flexible braided "wires" that will distribute the tension from the system throughout the upper part of the shoe for excellent ergonomics and overall foot comfort while also improving the security of the foot inside of the shoes for a more efficient transfer of power to the pedals. Controlling the tension of the system is a unique, user friendly dual dial system that can adjust the fit around the heel/arch portion of the shoe and the fit of the toe box of the shoe independently from one another. Finally, a rapid release function is integrated into both of the dials that allow large changes to the tension to be performed as needed in addition to making it easier to remove the shoes when the bike ride has been completed. Features: Dual dial design allows the heel/arch of the shoe to be adjusted independently from the fore-foot of the shoe, creating an optimal fit throughout the length of the shoe for comfort and performance Braided wire is durable, flexible, and stretch resistant to improve comfort, pressure distribution, and security of the foot Each package contains (1) pair of dial systems Specifications: Quantity: Pair Color: Blue/White Shoe Compatibility: Sidi Shot 2S Road Shoe | Sidi Tiger 2S Mountain Bike Shoes
