Prologo Proxim W400 T2.0 155mm Sport Saddle Hard Black

The Proxim W400 delivers versatile performance across diverse riding disciplines. Engineered for both pedal-assist and traditional bicycles, this saddle accommodates varied rider preferences without compromise. Its robust construction withstands demanding terrain, while the thoughtfully engineered cushioning system provides sustained comfort during extended rides. Whether tackling technical trails or navigating urban commutes, the W400's generous proportions and refined padding geometry ensure reliable support across all conditions.

Ergonomic shape

The Proxim W400 offers dual width configurations to match your riding style: the 153mm profile suits aggressive road cycling, while the 163mm accommodates touring, recreational, and commuter applications. Its compact 255mm length strategically minimizes pressure concentration in sensitive areas. Both variants feature a distinctively widened, angled nose that expands the support platform and enhances pedaling freedom when weight transfers forward during climbs or sprints.

Technologies

The W400 integrates Prologo's Multi Sector System, employing strategically mapped zones with differentiated foam densities and segmented padding that respond independently to shifting rider positions throughout the pedal stroke. The Active Base System incorporates a pressure-relieving cutout that optimizes load distribution across an expanded contact surface while offering weather protection against moisture and debris. Enhanced padding formulations—1cm on the 153mm and 1.7cm on the 163mm—deliver sustained comfort during marathon sessions. Additional refinements include an integrated rear grip for improved bike control and reflective detailing for enhanced nighttime visibility.

Base & Rails

The W400 foundation utilizes carbon-reinforced nylon with reinforced wall thickness, delivering the flex and durability essential for gravity-oriented disciplines. The T2.0 chromoly steel rail system provides optimal stiffness-to-weight characteristics and superior fatigue resistance. For environmentally conscious riders, the Re-Steel variant substitutes recycled steel rails with a recycled nylon composite base, maintaining performance standards while reducing material footprint without compromising comfort or longevity.
