You sit ‘into’ the Phobos rather than on it, and the feel is fairly firm. There’s enough room to get forward on climbs and that low seating position helps you lean your weight around through turns.
The Phobos is Selle San Marco's entry into the custom fit saddle arena. The SIZE system uses body size and weight to calculate the exact saddle shape that a rider needs in order to produce the most comfortable or healthy riding position.
The Phobos comes with titanium rails, a Lorica cover – which is lighter than leather – and built-in elastomers to reduce trail vibrations.
