The Zero-II is flat saddle ideal for short distance road and XC riding and frequent changes in the riding position. The new Space version has extra width, more generous padding with multiple foam densities and a more pronounced PAS channel. It’s suitable for men and women.


Specifications:


  •     Size (mm): 275 * 141
  •     Weight (g): 237
  •     Base: Carbon Fiber Injection
  •     Rail: TiroX
  •     Cover: Microfiber
  •     Padding: Light PU


Technologies:


Space: This is a modified version of the Prologo PAS technology. The cutaway eliminates pressure peaks and pelvic numbness. Unlike regular cut-outs, it remains effective over the course of long rides. Compared to PAS, SPACE tech features a larger anatomical channel that drives along the saddle around the central axis. The padding is 3mm thicker, and features multi density foam along the length. Furthermore, the Space saddles are wider for greater Ischial support. This technology is particularly suited to riders with wider sit bones/female riders.


TiroX: Lightweight alloy steel rail. This is an aerospace grade metal, with a high resistance to traction and torsion. Well suited to the stresses of a performance saddle, it offers a good alternative to carbon Nack rails. It has 7mm rail clamp diameter.


ESD: Ergo Shape Design: This is a refined saddle shape, developed as a result of biomechanical studies done by Prologo over several years. ESD saddles feature a slender front area and a short rear area that quickly reaches maximum width. This permits a round pedal stroke, allowing the rider to maintain a natural position.  The legs of the cyclist have more space during all phases of the pedal stroke, reducing friction and increasing alignment and performance. Finally, the opening swift of the rear part of the saddle helps the rider to find the correct support and support of the ischial bones. This prevents sliding forward and any rotation of the pelvis.


Active Density: This is the combination of different densities of foam and different rigidities in the base of the saddle, for optimal comfort and performance. At the rear the foam has a higher density for stability. In the centre the foam is of lower density, giving maximum comfort to the perineal area where pressure peaks can occur. In the tip of the saddle, the foam has a lower density, which allows a pressure reduction during maximum thrust. The Carbon Fibre Injection base also has variable rigidity, giving stability at the rear and comfort in the middle and front. Furthermore, the special openings in the hull make the base of the saddle more elastic to give extra comfort when pedalling in a relaxed position, whilst providing great stiffness during the phases of maximum thrust.
