The Vittoria Triathlon Evo CS tubular tire is a tri-specific tubular designed and built for Ironman racing. It has a handmade poly-cotton Corespun 320 TPI casing tubular structure for superior performance, low rolling resistance and comfort with a butyl inner tube that increases its elasticity and puncture resistance.
The butyl inner tube retains pressure better than any other tubular, which is ideal when leaving your bike in transition the day before your event. New high-density casing (a true 320 tpi) delivers unbeatable comfort and superior performance with inflation pressure of up to 200 psi.
Vittoria inserts PRB puncture-resistant belting under the tread to make the Triathlon Evo CS exceptionally reliable, while still maintaining very low rolling resistance. The tread is built with a silica enhanced Kevlar Carbon 3D SiO2 compound to give tires a longer wear life and increased grip in the wet.
