Improve your performance, the Fizi:k Tritone 5.5 is specifically designed to increase hip rotation to improve performance when riding in an aerodynamic position making it the perfect saddle for both triathlons & time trails. The comfort of the nose-less Tritone 5.5 saddle is created using specifically developed foam density & a front indentation channel that provides padding where necessary without putting pressure on sensitive areas. This braided carbon railed version of the Tritone 5.5 reduces weight by 30g & increases the saddles stiffness for enhanced efficiency. Description by Mark, Rutland Cycling Web Team.
