PROLOGO SCRATCH M5 PAS 140-Hard Black-Nack

The new saddle, like all high-performance models from Prologo, rests on a base made of injected long-fiber carbon, a material that offers an excellent compromise between lightness, rigidity, and comfort. As for the rail, you can choose either the Nack (Nano Carbon Fiber) version made of carbon fiber, Kevlar, and aluminum filaments, for maximum rigidity and lightness, or the Tirox rail version, made of lightweight alloy steel with an excellent weight-to-resistance balance, which gives the saddle lower rigidity and superior vibration absorption.
