Speaking for itself, Raddler is the radder version of WTB's famed Riddler tread pattern. It combines the expeditious efficiency of a short-knob centerline with the 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. - Fast rolling center knobs, tightly spaced in a consistent pattern, the center tread cuts down on rolling resistance while still digging into any terrain for dependable out-of-the-saddle traction - Supportive centerline provides a smooth, stable ride that instills confidence whether it’s the first or fourth hour of your weekend grind - Center and intermediate knobs on the Raddler are slightly taller than those on the original Riddler, thereby increasing tire lifespan with out negatively affecting rolling efficiency - Long, toothy side knobs ensure your favorite gravel descent won’t unravel in the final corner. The Raddler centerline may hug the road, but its side knobs are consistently jabbing for traction - Lightweight 120tpi casing combined with SG2 puncture protection that’s made from ultra-thin nylon inserts to provide bead-to-bead coverage, ensuring no area is left unprotected

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. SG2 PUNCTURE PROTECTION: These tires are available with our all-new SG2 Puncture Protection, which is a lightweight nylon insert that provides bead-to-bead coverage and ensures every area of the tire is defended against slashes and punctures. As events become progressively rougher and cyclists pedal farther, gravel gets tougher. It only makes sense for gravel tires to become tougher as well. - Nylon fibers have a flat profile, which reduces the amount of rubber needed to fill the gaps between fibers and minimizes weight. - Protected SG2 gravel tires feature a 120tpi casing, which improves suppleness compared to a traditional 60tpi tire. - SG2 was specifically designed to be a puncture protection layer, but it also improves air retention and eliminates seeping at the sidewall. 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.

Resolute 42 is the ultimate all-weather gravel tire for those who believe there is one perfect tread pattern for all your rides. Truly all-season in nature, we call this our set-it-and-forget-it tire that keeps on keepin' on. SG2 PUNCTURE PROTECTION: These tires are available with our all-new SG2 Puncture Protection, which is a lightweight nylon insert that provides bead-to-bead coverage and ensures every area of the tire is defended against slashes and punctures. As events become progressively rougher and cyclists pedal farther, gravel gets tougher. It only makes sense for gravel tires to become tougher as well. - Nylon fibers have a flat profile, which reduces the amount of rubber needed to fill the gaps between fibers and minimizes weight. - Protected SG2 gravel tires feature a 120tpi casing, which improves suppleness compared to a traditional 60tpi tire. - SG2 was specifically designed to be a puncture protection layer, but it also improves air retention and eliminates seeping at the sidewall.

Resolute is the ultimate all-weather gravel tire for those who don't want to fuss with conditions-specific tires for every season. Small, square knobs deliver consistent bite into a variety of terrain, while the ample spaces between them prevent packing up when conditions become fun (a.k.a wet). Truly all-season in nature, the Resolute's 42mm width makes it a set-it-and-forget-it gravel tire for endlessly undulating roads through all varieties of weather. Now available in 50mm width making the go to tire of choice for any adventure rider. Mud-Shedding Design Widely spaced square knobs deliver consistent traction while shedding mud or clay with ease. Performs well in all conditions, which means there is no longer a need to swap tires based on the weather. Consistent Square Knobs There are numerous ways to increase the speed of a gravel tire, but consistently spaced knobs with substantial surface area is the best way to achieve it. Resolute excels in efficiency by staying on the surface of the terrain until pedaling or braking forces it to dig in. Supported Outer Knobs Rows of outer knobs are connected by a supportive base that runs the entire circumference of the tire. Additional rubber at the knob bases allow them to dig in without the unsettling feeling of a knob folding while cornering. This make the Resolute one of the most confidently cornering gravel tires in our line. TCS Tubeless-Ready TCS (Tubeless Compatible System) is WTB's standardized tubeless system. These tires feature a TCS tubeless-ready casing, which nearly eliminates flats and allows lower tire pressures to improve traction and comfort over a traditional tube-type tire. Available with SG2 puncture protection SG2 is our unique puncture protection technology that provides bead-to-bead coverage to ensure both the tread and sidewall are protected from slashes and punctures. The nylon fibers within SG2 feature a uniquely flat profile, which reduces the amount of rubber between fibers. Improving the fiber-to-rubber ratio increases puncture resistance, reduces weight and improves the overall liveliness of a tire. While SG2 is primarily a puncture protection layer, its tightly woven fibers also improve air retention to better maintain pressure between rides. Black or Tan Sidewalls It's nice to have options, which is why most of our gravel tires are available with either black or tan sidewalls. Traditional black sidewalls tend to blend in with the components and wheels of a bike and may look sleeker in the eyes of some riders. WTB tanwall tires blend retroesque looks with modern technology to create an iconic look that has become synonymous with high-performance gravel. Looks aside, gram counters may choose our tan tires because the compounds used to make them are slightly lighter than those used to manufacture black sidewalls. Description missing for this image.
