T5/T7 Speed and Grip in One TireGRIPTON T5 in the center is Specialized’s fastest-rolling compound minimal resistance on the straights and flat sections. T7 on the shoulders provides confident cornering grip without the drag penalty of a full grip compound. The dual-compound design means you don’t have to choose between speed and traction.5% Faster Rolling, 55g LighterThe reduced knob height and compact center design are the keys to the Flex Lite’s advantage. Shorter, smaller center knobs mean less rubber in contact with the ground, less weight, and less rolling resistance. The 5% improvement in rolling resistance and 55g weight savings translate directly to faster race times especially on courses with significant flat or rolling terrain.Flex Lite Casing Specialized’s Lightest XC CasingThe 60TPI Flex Lite casing is Specialized’s lightest XC construction supple, compliant, and race-optimized. It absorbs trail vibration and maintains traction better than heavier casings, while still providing the durability needed for race-day confidence. Compared to the Grid Lite or Grid Trail casings, Flex Lite is the lightweight champion of the lineup.GeneralModelFast Trak Flex Lite T5/T7 TLR XCPositionFront & RearUseXC Racing & RidingTerrainMixed XC conditionsTypeTubeless Ready (TLR)Tread & CompoundCompoundGRIPTON T5 (center) / GRIPTON T7 (shoulder) dual compoundTread DesignCompact center knobs, Block-In-Block outer knobsCasing60TPI Flex Lite Specialized’s lightest XC casingWeights29 x 2.2″605g29 x 2.35″615gPerformanceWeight Savings55g lighter than standard Fast TrakRolling Resistance5% improvement vs standard Fast Trakfunction showPanel(id, btn) { document.querySelectorAll(‘.spur-panel’).forEach(p => p.classList.remove(‘active’)); document.querySelectorAll(‘.spur-tab’).forEach(t => t.classList.remove(‘active’)); document.getElementById(‘panel-‘ + id).classList.add(‘active’); btn.classList.add(‘active’);}
