This is a new Phemom saddle with carbon rails, carbon base and 143mm width. 191g. The curious thing is this is a take off from an S-Works Epic Evo complete bike. Bike specs states that the bike comes with an S-Works saddle. But its not marked S-Works. Its slightly heavier than the claimed weight of 141g for S-Works but lighter than the claimed weight of a Phenom Pro saddle. Weight is 191g. So take that into consideration. Pricing it much lower than an S-Works and even lower than a Pro.
