Specialized Fast Trak Flex Lite T5/T7 TLR XC Tire
Product Details
The Specialized Fast Trak delivers uncompromising speed, control, and confidence across every trail condition. Designed for elite cross-country racers and performance-driven riders, this meticulously engineered tire combines lightweight efficiency with all-conditions traction, proving that top-tier speed doesn’t have to come at the expense of grip or durability.
Its optimized tread design features tightly spaced center knobs for low rolling resistance and rapid acceleration, while aggressive Block-In-Block shoulder knobs bite into corners for maximum control when the trail gets technical. This intelligent redesign trims 55 grams of rotating weight and improves rolling efficiency by 5% over the previous generation—delivering faster climbs, snappier acceleration, and consistent traction across mixed terrain.
The GRIPTON dual-compound T5/T7 system further refines performance with a harder T5 center for speed and longevity, paired with a softer T7 shoulder for cornering stability and bite. This dual-zone approach eliminates the trade-offs of single-compound tires, maintaining both momentum and traction under demanding race conditions. The 60 TPI Flex Lite casing adds supple compliance and control without sacrificing puncture resistance, while the tubeless-ready construction allows lower pressures for greater grip and comfort with zero pinch-flat risk.
Available in 29x2.35” (615g) sizes, the Fast Trak integrates seamlessly with modern XC geometry to deliver the ultimate balance of efficiency, traction, and confidence for racers who refuse to compromise.
