Thanks to its “T Shape” design, size and ergonomics the M5 Scratch range is suitable for use by both men and women. Coming complete with a range of performance-enhancing technologies including a PAS System that runs down its centre section, this model is designed to eliminate pressure and numbness as well as increase comfort.Tour de France WinnerThe Saddle that won the Tour de France 2020 and 2021, the Scratch M5 uses 4.0 technologies; innovative in terms of size, shape and ergonomics, they are suitable for multiple uses and disciplines (Road / Off Road), including the Triathlon. Climb, sprint or long stages: no matter the challenge faced, the Scratch M5 was Pogaçar’s perfect ally to become the best climber, the best youngster and the best overall.MSS Multi Section SystemThe MSS Multi Section System seating system, designed in co-operation with the Polytechnic University of Milan, helps improve comfort and performance. The active foam is separated to create 5 zones working in a smart and individual way that favours natural pedalling movement. This absorbs the vibrations that the carbon fibre body transfers to the over-saddle. The Round Shape of the M5 creates stability and support for your lumbar areas and distributes pressure on a greater surface.Carbon Long Fibre ShellThis material improves the stability of the saddle base, providing reduced pressure and less reaction during the push and pull phase. In combination with the Tirox Rail the saddle guarantees excellent performance and comfort.Comfortable PAS SystemThe PAS system is a channel in the base of the saddle. The hole or channel helps to maximise blood flow and supports the pelvic area while also preventing pressure peaks. This system is designed and developed to eliminate pressure and numbness to areas that need it most.Features: Shell Material: Carbon Fibre Rail Material: Tirox (Light Alloy Steel) Padding: Multi Section System (MSS) Use: Road, Gravel and Triathlon Size: 250x140mm Gender: Unisex Central Cut Out: PAS System Weight: 185gTechnologies: Tirox Rail: Light alloy steel, highly resistant to traction and torsion; for its physical characteristics and lightweight, it’s used in the aviation and aerospace industry.
