The Selle San Marco Mantra Xsilite pairs stainless steel Xsilite rails with Pullfoam padding that shifts with the pelvis while pedaling, so the saddle holds up to off-road abuse without adding bulk. The carbon-reinforced shell and Silkfeel cover keep mud and water out, so the saddle stays dependable ride after ride. What Our Gearhead(R) Experts Are Saying:"I move around this saddle constantly picking lines through technical sections, and the delta shape keeps me centered no matter where I end up on it. Coming back to the nose after a scramble doesn't cost me a second of control."
