Prologo Nago Evo Nk Saddle with Nack Rails

It offers great versatility for riders that like a choice of riding positions. It's equally suited to weekend rides and racing.

Nack: Nano carbon fibre rail. In addition to the carbon, Kevlar and aluminium filaments are integrated into the seat-post clamp area and are arranged in a production process called Braided Carbon Rail (BCR) to give strength. Nack rails give the optimal weight and durability required of a performance saddle. It has 7x9mm oval rails.

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.
