    At first glance, the Fi'zi:k Triton 5.5 Saddle looks—there's no other way to put it—weird. Then, when you hear it's designed to increase aerodynamics, it makes even less sense. How does a fat squared-off nose help you cut through the air more efficiently?

    It turns out that it’s not the saddle itself that's more aerodynamic, but the body position that it allows you take. It lets you sit lower and with your hips rotated forward, flattening your back to reduce the drag that's caused by your body, which can help you save valuable seconds in a triathlon or time trial. The Tritone is comfortable, too, which a deep center channel that takes pressure off sensitive areas and varied-density foam that supports your sit bones.

    Underneath the foam, the shell of the Tritone is made from carbon-reinforced nylon, a stiff but comfortable platform that provides plenty of power without feeling like a 2x4. The Microtex synthetic cover is thermowelded, not stitched, which creates a waterproof and airtight seal for increased durability and smoothness, and is finished with silicone strips to keep you from slip-sliding around like a wet seal on an iceberg. Fi'zi:k constructed the long 85mm rails from its special K:ium alloy, which is strong and lighter than pure titanium, and engineered a transition hook into the nose of the saddle for smooth and easy triathlon transitions. There's also a carriage kit on the back, which is designed to hold bottle cages, CO2 canisters, an inflator, and a tube.

    How does it compare to the Adamo?

    Best Answer

    Hey, I've put several thousand miles each on ISMs Adamo Road and Adamo Podium. Of the two, I prefer the length of the Podium and the larger surface area which translates into a wider range of viable positions.

    This saddle looks more like the Road than the Podium. I would expect positions to be fairly limited. I'm curious about how the separate rails on the split nose of the Adamos would compare to the Fizik groove. At a glance, the sides of the Fizik groove are much narrower than the Adamo nose pieces. That would put more pressure on a riders bones and bits on the Fizik than the Adamo. What's nice about the groove, is that the structural integrity and shape of the Fizik should be much better. That's a place where the Adamo has integrity challenges--the saddles can bend more easily than a traditional saddle.

    I would suggest considering the Fizik for TTs. The Adamos are probably better all around road saddles. It's nice that Fizik chopped out so much weight, but when they did so they probably ended up limiting the riding positions as well as the durability of the saddle for heavy road use.
