The Fi’zi:k Ardea Versus Manganese Saddle incorporate a pressure relief area into the most popular Spine Concept shapes. Fi’zi:k believe comfort is achieved by optimising the seating surface area and that full cutout designs decrease seating surface and support. Versus saddles have the same surface area as the corresponding solid surface saddles and use the same base as the current road saddles to maintain structural integrity. Saddles with cut-outs have a weaker base structure, and begin to flex and sag immediately in use. The Ardea Versus use the optimum ergonomic channel shape to ensure pressure relief and support without involving the sharp edges common in cut-out saddles.
