Selle Italia Watt 3D TI 316 Superflow Saddle

The Selle Italia Watt 3D TI 316 Superflow Saddle was designed specifically for the demands of triathlon — where your position on the bike is aggressive, sustained, and non-negotiable. The shell is built using a 3D-printed construction with a double-layered padding structure, intended to deliver progressive cushioning across different load zones. The Superflow central cut-out removes pressure at the perineal area, which matters most when you're locked into an aero position for hours at a time.

The rails are titanium 316 — a grade chosen for its combination of low weight and tensile strength relative to standard steel. At 133mm wide, the saddle suits riders who carry their weight through the sit bones in an aggressive forward rotation. Developed with input from professional triathlon athletes, the Watt 3D is shaped to keep you planted and stable through the pedal stroke rather than constantly micro-adjusting your position.
