The T-Serv Protite is an urban favorite that's also getting lots of use by gravel riders. ProTite technology enhances the tire casing to improve puncture resistance without a separate belt that would increase rolling resistance. ProTite is a proprietary additive that adheres to the casing and provide 25% more puncture protection than Panaracer's previous technology. Zero Slip Grip Natural tread compound integrates more natural rubber to decrease rolling resistance and increase tread wear life. 400D Lite Extra Cord technology increases side-cut resistance while improving the rigidity during cornering.
