Sillín Selle Italia SP-01 Boost Superflow Tekno

Selle Italia SP-01 Boost Superflow Tekno Saddle strips the standard Tekno Superflow down to its structural essentials — a fully exposed carbon fiber shell with no top padding or cover. Selle Italia developed the shell with Dallara, the Italian firm known for composite work in Formula 1, and paired it with hi-tech carbon rails measuring just 7x9mm. The result is one of the lightest road saddles in Selle Italia's lineup.

The Superflow cutout runs the length of the saddle to relieve perineal pressure and keep blood flow moving on hard efforts, while Selle Italia's Suspension Link Movement lets the rear sections of the shell flex independently side to side. That flex tracks the natural rocking of your hips as you pedal and adds a degree of shock absorption at speed, most noticeable when you're pushing hard rather than sitting in at an easy pace. Combined with the Boost's shortened length, it keeps the nose out of the way for riders who spend time in the drops.

This is a race saddle in the fullest sense — no padding means fit and sit-bone position matter more than usual, and it rewards riders already dialed into their position rather than those still hunting for one. For racers and weight-conscious road riders building out a lightweight setup, the SP-01 Boost Superflow Tekno is Selle Italia's most stripped-down carbon saddle.
