Using the automotive analogy, the Tecnica Firebird R 90 SC is like a junior formula car: a pure racing vehicle designed to scale for lighter drivers. This is not a recreational cruiser; it is a machine born for the track. Its defining feature is the SC (Short Cuff) design, which reduces the height of the upper cuff. This is the equivalent of adjusting the cockpit seat and steering column so that young racers or shorter women can flex properly without the boot blocking their center of gravity.

The chassis is built from high-density Polyurethane (PU) and features a 96 mm Low Volume (LV) last, ensuring the foot is completely immobilized with absolutely no steering play. Every knee movement translates instantly into a direct command to the ski edges, achieving aggressive cornering with zero understeer.

Inside, the Race Dept. liner offers a millimeter-perfect bucket seat fit, designed to maximize terrain sensitivity and energy transfer. Finished with 4 micro-adjustable low-profile buckles and a 35 mm Power Strap acting as a tibial harness, this model is the perfect engine to take you to the podium.
