Specialized Ruby Expert Saddle

Body Geometry is Specialized's proprietary ergonomic approach, which uses medical data to ensure the saddle supports your sit bones properly while reducing pressure on soft tissue. It is designed to align your hips, knees, and feet to prevent discomfort during longer rides.

The Adaptive Edge base is engineered to allow the edges of the saddle to conform to your body's movement as you pedal. This flexibility helps the saddle feel less rigid, effectively minimizing friction and pressure points while you are in motion.

The 143mm width is a standard size that fits a wide range of cyclists, but saddle fit is highly personal. We recommend getting a sit-bone measurement at a local bike shop to confirm if this width provides the correct support for your specific pelvic structure.

Yes, hollow-titanium rails are an excellent balance of strength and weight reduction. They are durable enough for everyday road riding and offer a slight amount of vibration damping compared to solid steel rails, which can help smooth out road chatter.

The central cutout is specifically designed to alleviate pressure on sensitive areas, which is crucial for maintaining blood flow during long rides. By removing material where you don't need it, the saddle prevents numbness and allows for a more comfortable, upright, or aggressive riding position.
