Punctures suck, which is why Specialized incorporated their legendary Armadillo flat-resistant technology into the Fast Track Armadillo tire. Not only that, but they also took the tread design of the Fast Trak a step further by manipulating each knob with FE Analysis. Paired with extensive rider feedback and design experience, the result is a XC tire with less rolling resistance and more traction, all with Armadillo maximum puncture protection from bead to bead.
