Scratch M5 PAS AGX Slide Control

Scratch M5 PAS AGX Slide Control is the innovative gravel-specific version of Prologo’s iconic round-shaped saddle. AGX, which stands for Adventure - Gravel - Cyclocross, is a line of ergonomic saddles dedicated to the gravel and all-road world, designed to provide the ideal balance between performance and comfort across all terrains—even over long distances.

Compared to traditional models, AGX saddles feature a more flexible base made with next-generation materials and an extra 2mm of low-density foam padding. These characteristics ensure better shock and vibration absorption, without limiting or compromising power transfer, even when riding off-road.

Anatomical Shape

The distinctive T-shape of this saddle offers greater freedom of movement and positioning, delivering comfort and protection in areas prone to friction.
The rearward anatomical center allows the rider to easily change position and make full use of the saddle’s length. The rounded anatomical shape of the Scratch M5 AGX provides extra lumbar support, helping to maintain a stable position even for riders with reduced pelvic mobility.

Technologies

The Multi Sector System features mapped and separated zones on the saddle, each made up of different interactive foams and single-cell separated padding.
Prologo’s 3D Slide Control technology improves grip and rider stability, helping maintain proper saddle position even on technical off-road sections.
The PAS channel (Perineal Area System) relieves pressure and numbness, increasing blood circulation. The ergonomic design and variable-density foam eliminate pressure points in the perineal area.

Base and Rails

The rail is available in Nack (Nano Carbon Fiber): made of carbon fiber, Kevlar, and aluminum filaments—perfect for riders seeking maximum stiffness and lightness- or in Tirox (light alloy steel): offering excellent vibration absorption and a great weight-to-strength ratio. The base is made from long carbon fiber for the Nack rail, or in injected carbon fiber for the Tirox rail. Materials offering a great balance between stiffness and comfort.
