This TLR clincher with 120TPI nylon casing provides both performance, durability, and puncture protection when combined with the appropriate tubeless sealant. TLR - TLR tires versions can be ridden tubeless with the addition of sealant but can also be run with an inner tube. - A bead-to-bead inner coating gives added puncture protection to these tubeless ready tires and greatly reduces gradual loss of air pressure. An aramid bead protection strip increases tire longevity and reduces rim chafing.

P ZERO Race TLR synthesizes the advantages of the tubeless technology in an all-rounder cycling tire for high-intensity training sessions and races. The TechWALL+ Road carcass improves reliability against punctures without affecting the weight of the tire, while the special SmartEVO Compound enhances grip performance both on wet and dry asphalt compared to our previous cycling compounds. The tread pattern of P ZERO Race TLR is an evolution of the design of P ZERO Velo: several seasons of research and development on the roads of the World Tour led to a new design that enhances the behavior of the bicycle in all weather conditions. - Using experience from World Tour racing, coupled with a constant desire for excellence, the Pirelli engineers have developed the best-performing all-around bicycle race tire ever conceived by the iconic brand. - The P ZERO Race TLR is crafted to pack all the benefits of tubeless technology into a race-ready all-rounder that outperforms all cycling clinchers that we have created before, tubulars included. - After three years of development working with the fastest racers at the World Tour level, including men's and women's 2019 UCI World Champions, Pirelli designed this new tubeless-ready tire with the new SmartEVO compound and the TechWALL+ casing technology to provide our professional riders, as well as all cycling enthusiasts, with a superior product! - SmartEVO Compound is a new formulation that enhances the already excellent performance of our previous road cycling compounds. The experience of motorsport competitions and World Tour winner input led to our best road cycling compound ever. - Techwall+ Road: New TLR casing technology with multiple layers of reinforcement provides superior puncture protection with lightweight construction.

Speaking for itself, Raddler is the radder version of our famed Riddler tread pattern. It combines the expeditious efficiency of a short-knob centerline with get-rad traction of chunky outer knobs. Let’s call it a semi-slick, but one designed to increase confidence while you’re pushing the limits of gravel. Raddler is an excellent choice for loose terrain where traction takes priority, but efficiency is never far behind. Lean it over, take the inside line, brake late, and stay pinned with the Raddler. FEATURES: - Short-knob center tread cuts down on rolling resistance while still providing enough bite for out-of-the-saddle traction. - Center and intermediate knobs on the Raddler are slightly taller than those of the original Riddler, thereby increasing tire lifespan without negatively affecting rolling efficiency. - Tall, toothy outer lugs ensure your favorite gravel descent doesn't unravel in the final corner. - Single-ply, 60tpi casing provides dependable protection at a minimal weight. - Available with black or tan sidewalls in 40mm and 44mm widths. - All Raddler tires are TCS tubeless compatible.

Continental's ultra-tough Gator Hardshell combines 3 flat-protection technologies into the ultimate distance and training tire.
