PERFORMANCE - The design of the rails in this saddle is straight, as a central spine, rather than splayed outwards underneath the seat bones, as they commonly are in most saddles. Sitting on the rails would be less comfortable or require more cushioning. In the Luce, the wings flex for comfort and support. The straight rails also are a performance feature that creates more power transfer to the pedals. As the rider pushes against the back of the saddle, less power is absorbed by cushioning. For straight rails to be stable, I also designed a bridge structure to keep them held parallel.
