Joining the world of 3D printed saddles, the Selle Italia SLR 3D Boost Superflow Kit Carbon Saddle is a must-have for our next bike build. With Superflow technology and its proprietary 3D printed pattern, Selle Italia brings us a new world of comfort by reducing prolonged pain in the perineal area and adding extra cushioned zones to deliver excellent shock absorption. With every pedal stroke, the Hi-Tech Carbon rails provide extra support and durability so we can climb and descend confidently.
