SIDI CLOSURE TECHNOLOGY
As the world moved from the culture of the eighties to the new nineties, we were doing what we do best: making better cycling shoes and in the constant quest for a better fit, SIDI invented the world's first rotor, achieving something unthinkable at the time: a firm, solid closure with infinite adjustment possibilities.
Fit Technology
NUUN 001R™ DIAL SYSTEM
The NUUN 001R™ dials are precision-milled from aluminum for strength and minimal bulk. Their aerodynamic shape reduces drag, while Sidi’s integrated handle mechanism allows high-torque tightening when activated. The system also functions seamlessly even when the lever is closed, ensuring consistent, micro-adjustable fit with every turn.
Fit Technology
DIAL SYSTEM
The dial system is a high-precision, micro-adjustable closure mechanism engineered by Sidi since 1988. Designed to deliver a secure, uniform fit, it employs rotating dial actuators connected to low-friction cables, offering adaptive tensioning across the shoe’s upper.
Fit Technology
FIRMOR CLOSURE
The integrated Firmor lateral technology is designed to stabilize the foot even during the most intense performances, delivering a feeling of total control.
Fit Technology
STRAP CLOSURE
The Strap Closure is equipped with internal teeth for a secure hold. This isn’t just a strap—it’s a patented tension strap system that ensures constant tension, allowing for infinite individual adjustments. Designed for precision and reliability, the Strap Closure guarantees a secure hold in all conditions.
Fit Technology
INSTEP CLOSURE SYSTEM
The SIDI instep system uses a high-density, anatomically shaped strap to wrap the foot securely across the instep. It adjusts quickly and evenly, ensuring comfort and control during extended efforts.
Sole Technology
Sidi’s soles are engineered for top-tier performance using advanced composites like nylon reinforced with carbon fiber—resulting in ultra-stiff, lightweight construction that maintains rigidity in hot or humid conditions. In select models, their replaceable Sole Replacement System (SRS) adds modular durability and improved heat dissipation for lasting precision and comfort.

R2FC
The R2FC Sole is crafted from full carbon, boasting a stiffness index of 11. This advanced design ensures maximum rigidity and power transfer for an unparalleled cycling experience. Engineered with an innovative airflow system, the sole features internal channels that promote air circulation between the sole and the insole, keeping feet cool and comfortable during rides. The sole is equipped with rubber inserts at the toe and heel, with the heel insert being replaceable. The robust heel design enhances ground contact for improved walking stability. Cleat positioning is highly customizable, allowing for a real adjustment range of 12mm. The single cleat plate ensures ease of use and provides added robustness for secure engagement.

AEROLITE
Aerolite sole is the sole designed to maximize aerodynamics and power transmission on the bike. The composite material made of nylon and carbon fiber provides the perfect balance of stiffness for effortless and comfortable pedaling.
-
C-BOOST SRS
Made of the latest generation carbon, thanks to the special conformation of the metatarsal area, it increases the transmission of power directly on the pedals, guaranteeing ideal power transfer and support. The oval holes extend the adjustment the position of the cleat by ± 5 mm of a millimeter scale is included for remembering the riders personal cleat position. Provided with SRS (Sole Replacement System) inserts in Nylon and TPU, with the function of protecting the carbon in the areas most subject to deterioration from use and for increased durability while walking. The SRS inserts are integrated by ventilation holes that promote the circulation of air inside the sole with each pedal stroke.
