Features of Prologo Scratch M5 PAS AGX

Product description of Prologo Scratch M5 PAS AGX saddle

Description summary

Conquer any terrain with the Prologo Scratch M5 PAS AGX saddle. Specifically engineered for gravel, adventure, and cyclocross, it masterfully balances performance and long-distance comfort. Its AGX design features a flexible base and extra padding to absorb vibrations without sacrificing power. The T-shape allows freedom of movement, while the round profile provides crucial lumbar support. Advanced tech like the Multi Sector System, pressure-relieving PAS channel, and Slide Control for grip ensure you stay stable and comfortable on the most demanding rides

Scratch M5 PAS AGX Slide Control Tirox 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.

Honestly, a great saddle, super comfortable even after several hours of cycling. The channel in the middle prevents pressure, and you stay well wedged thanks to the Slide Control. Light but sturdy, you can feel that it's quality equipment. Nothing like what I had before. I don't regret my purchase at all. A very pleasant surprise, I recommend it!!!
