As the name suggests Terry went to the drawing board to design a saddle that would maximize comfort over miles and miles 100 even. The most important feature for this endurance comfort is a layer of Poron XRD shock absorbing material. Placed between the saddles base and foam layers it helps absorb road vibrations and allows for less foam padding to be used for a thinner profile. To further help long ride comfort is a wider cutout for increased pressure relief. A seamless Lorica cover minimizes friction and Ti-Nox rails are light and strong.
