It has a semi round shape, and dropped nose well suited for set ups with large saddle to handlebar drop. The hull is designed for flex, which helps the saddle adopt a hammock shape in use, aiding comfort.

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.

T2.0:  Chromium rails with a high hardness index. They give the perfect blend of mechanical resistance and compliance over a long lifespan.  The material is chosen for its ability to deal with impacts and stresses.
