Specialized Ruby Expert Saddle

The correct width depends on your sit bone measurement, not your pant size. Specialized retailers use a sit bone measuring tool to determine your specific width, ensuring you get the proper support for your pelvis.

The Adaptive Edge base is designed to flex at the edges of the saddle. This allows the saddle to conform to your body's movement as you pedal, reducing pressure points and preventing chafing during longer rides.

Yes, the Ruby Expert is specifically engineered for endurance riding. The combination of the carbon-reinforced shell and ultra-light foam padding provides a balance of stiffness for power transfer and compliance for comfort over many hours in the saddle.

Hollow-titanium rails offer a high strength-to-weight ratio, which keeps the saddle light without sacrificing durability. They also provide a slight amount of vibration damping compared to solid steel rails, which helps smooth out rough road surfaces.

Body Geometry is a design philosophy focused on aligning your hip, knee, and foot to reduce injury and improve efficiency. In this saddle, it manifests as a specific shape and cutout that relieves pressure on sensitive soft tissue while supporting your skeletal structure.
