Prologo Scratch M5 AGX 140 Tirox Hard Black

The Prologo Scratch M5 AGX Tirox (Hard Black) is a premium all-terrain saddle designed for riders seeking the perfect balance of comfort, control, and durability across gravel, road, and adventure riding. Developed as part of Prologo’s AGX (Adventure – Gravel – Cyclocross) range, it’s engineered to perform consistently across mixed surfaces and long-distance rides.

Featuring the iconic Scratch M5 T-shape design, this saddle offers greater freedom of movement and improved comfort in key contact areas, making it especially suitable for riders who frequently change position on varied terrain.
