Proxim W400 is a saddle from the Proxim range designed to suit all types of riders, making it ideal for both e-bikes and mechanical bikes. This comfortable and durable product is perfect for off-road use as well as for daily commuting, thanks to its generous dimensions and carefully developed padding. The saddle is shorter at 255mm and wider at 150mm with a semi-round shape, which provides comfort no matter what it's being used for and is ideal for long distance riding. Along the edges of the saddle, the Proxim W400 is more flexible, allowing greater freedom of movement. The tip of the saddle has been increased in size and, at an angle of 30deg is much more flexible than a standard saddle. The Proxim also features the PAS system, which 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. The Rear Cover on the saddle is designed to increase grip in all weather conditions. The saddle is also equipped with a rear 'handle' to help with moving the bike on to bike racks or gondolas, as well as a graphic with reflective materials to improve safety. Tech Specs Size: 255 x 153mm Rail: Recycled Steel Cover: Microfibre + Grip Padding: Soft and thick Foam Weight: 290g The MSS,  Multi Sector System features different mapped and independent zones on the saddle, each made with various interactive foams and single-cell separated paddings. These “islands” work independently, adapting to all the positions the rider may assume while pedaling. The Active Base System includes a base with a cut-out designed to relieve pressure and increase weight distribution thanks to a broader support surface, while also providing protection against water and mud in the most extreme weather conditions. The softer and thicker foams used for the W400 saddle padding ensure a high level of comfort, allowing the rider to remain seated even during long rides (1cm thickness for the 153mm version; 1.7cm for the 163mm).
