W400 completes the Proxim range, making it ideal for both e-bikes and standard bikes, for off-road use but also for commuting / leisure use thanks to its size and padding levels (Multi Sector System). Proxim W400 is available in 2 widths: 153mm (for a more sportive use) and 163mm (for a more trekking, leisure and commuting use); thanks to its short length (255mm) the contact points and pressure peaks in the perineal area are reduced.
