Description & Features
Race ski bindings built for World Cup performance, the Fischer RC4 Race Bindings deliver precise power transfer, consistent release, and race-proven control. Designed for SL, GS, and speed disciplines, the RC4 lineup keeps you connected to the ski while allowing it to flex naturally through every turn.
At the core is Freeflex Pro, which allows the ski to flex freely under the binding for smoother energy transfer and better edge hold. Combined with FRP technology and a diagonal release system, these bindings provide a stable, responsive feel with reliable safety at speed.
From elite racers to juniors progressing through the ranks, the RC4 series offers a full range of DIN options. Each model is tuned for specific skier weights and performance levels, delivering confidence on hard, icy race surfaces.

Binding Technology & Construction
Freeflex Pro
A freely suspended heel allows the ski to flex naturally under the binding. This improves edge grip, ski control, and overall responsiveness through the turn.
FRP (Four Roller Pivot)
Four rollers and glide inserts enhance elasticity and optimize release characteristics. This helps maintain consistent performance under varying loads and conditions.
Full Diagonal Toe
Provides 180° release in multiple fall directions to help reduce stress on ligaments, especially in the knee.
Diagonal Heel
Features a 150° release arc to reduce forward twisting release forces while maintaining strong retention during aggressive skiing.
AFS (Anti-Friction Slider)
Ensures smooth, consistent release by minimizing friction from snow, ice, and debris under the boot.
