Fizik TRITONE Saddle K:ium Rails
Tritone is the ultimate saddle for Triathlon and TT. Its shape allows the best aerodynamic performance with the maximum riding comfort.
This saddle is so comfortable I even have one on my road bike, despite the weird looks its worth it. Keep in mind that if you mount water bottles behind it that they can launch just like any other saddle with hydration behind it. You can not fit a saddlebag if the waterbottle cages are mounted on the saddle, not that you should need one. Rubber bands and velcro hold a tube, levers, two co2 cartidgers, and the adapter to the spot built into the saddle.
