The Prologo Proxim W850 143 Nack Saddle represents a breakthrough in saddle technology, specifically engineered to meet the demands of E-Bike riders. Developed through an extensive design challenge at the Politecnico University of Milan, this saddle combines cutting-edge research with practical innovation to enhance every ride. Its unisex design ensures optimal comfort and support for all cyclists, regardless of gender.
Featuring the revolutionary Multi-Sector System, the saddle is divided into three distinct zones, each with unique interactive foams and single-cell pads that adapt independently to your riding position. This intelligent design minimizes discomfort and pressure, allowing for longer, more enjoyable rides. The PAS system further improves comfort by incorporating a channel in the base that maximizes blood flow and relieves pressure in sensitive pelvic areas, reducing numbness and fatigue.
Crafted with Prologo’s advanced Nack rail, made from monocoque carbon fibre and enhanced with BRC nano carbon technology, the saddle offers exceptional stiffness and lightweight performance. This combination provides unmatched durability and responsiveness, ensuring your saddle remains stable and supportive under all conditions. With a microfibre cover and mixed light foam padding, the Proxim W850 143 Nack Saddle is the perfect blend of innovation, comfort, and style.
What makes the Multi-Sector System unique?
The Multi-Sector System divides the saddle into three zones with different foams and pads that work independently to adapt to your riding position, ensuring maximum comfort and pressure relief.
Is this saddle suitable for both men and women?
Yes, the Proxim W850 143 Nack Saddle is designed as a unisex saddle, offering ergonomic support that fits both male and female anatomies.
