Fischer - 2017 RC4 Z 20 FF X


Paired with Fischer World Cup or Race Booster plates, the 2015/2016 RC4 FreeFlex Race Service bindings are designed for elite racers. With full metal toe and heel piece housings, these Race Service bindings provide both the weight and retention qualities that top-level racers need when competing on the world’s toughest courses. FreeFlex technology, meanwhile, ensures the advanced ski-to-binding compliance needed for a smooth and even flex pattern throughout the entire turn, effectively minimizing the feeling of a dead spot underfoot.


And when it comes to racer safety, the RC4 Z16, Z18, and Z20 are truly elite. Race Diagonal technology moves the release rotation axis in line with the shaft of the leg, greatly reducing the risk of injury during awkward, twisting falls. The result is less strain on ligaments and tendons in the leg, while still allowing for the higher DIN settings needed for proper retention. The new adjustable toe height feature, meanwhile, ensures proper lug-to-binding interface even when race boots have had physical alignment alterations.

With a slightly smaller spring and DIN-range of 8 - 16, the Z16 is ideal for adult slalom racers or junior speed disciplines.


RC4 Z18 FreeFlex Race Service

With a DIN-range of 8 - 18, the Z18 offers outstanding performance on Masters speed skis or as a tech binding for heavier racers generating large amounts of force.


RC4 Z20 FreeFlex Race Service
