Stay comfortable.

Fizik designed the Tritone 5.5 Carbon Braided Rails Saddle to strike the perfect balance between maximum aerodynamic performance and extended riding comfort. Fizik accomplishes this through the saddle’s strategically varied foam density and an indentation that increases toward the blunt nose. The Tritone’s shape keeps the pressure on your sit bones, even when you’re draped over the bars. For the shell, Fizik uses nylon reinforced with carbon fiber, making it lightweight and stiff. The shell is covered with a Thermo-welded Microtex that provides a waterproof and airtight seal.

The Tritone 5.5 also features a Front Transition Hook, and the carriage kit off the back allows you to easily attach two bottle cages, CO2, an inflator device, and a spare tube. With an extended saddle length of 24cm, the Tritone is compliant with UCI rules.

Rails too think for Cervelo P2 seat clam

  • Familiarity: I returned this product before using it

Really was hoping the Tritone 5.5 w/ Carbon Braided Rails would be an awesome addition to a 2015 Cervelo P2, but the think carbon rails were too think for the seat post clamp. Unable to comment about ride quality, but hope this helps others avoid a similar fit mistake.

Best saddle I have ever used.

  • Familiarity: I've put it through the wringer

I have owned this saddle five months and used it on my tri-bike in rain and shine, wind and hills. I have only logged about 2000 miles on it so far, and not more than 90 in a single time, but there has been no pain at all. That is monumental for me. I am 100% impressed! Thanks, Fizik! Love the Tritone 5.5!
