Female specific modifications include a multi-level cutout generous padding & a specific 147mm width. Specifications: Size (mm): 263 * 147 Weight (g): 282 Base: Nylon Rail: T2.0 Cover: Microfiber Padding: Light PUTechnologies:T2.0: Chromium rails with a high hardness index. They provide the perfect blend of mechanical resistance & compliance over a long lifespan. The material is chosen for its ability to deal with impacts & stresses.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 & 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 & increasing alignment & performance. Finally the opening swift of the rear part of the saddle helps the rider to find the correct support & support of the ischial bones. This prevents sliding forward & any rotation of the pelvis.
