The Torchbearer offers versatile performance in a variety of road conditions. Our progressive tread design provides excellent grip and handling to support your town-line sprint while providing low rolling resistance for long days in the saddle. The Torchbearer is available in both Tubeless Ready and tube-type constructions. The Tubeless Ready version utilizes Stage 4S Armor construction which combines three separate components of flat protection including a 120 TPI skin, a lightweight Nylon105 belt and our anti-cut deflecting skin to boost confidence and durability on long rides and in any weather. The tube type version uses a Stage 4 Armor construction which combines two separate components of flat protection including a lightweight puncture resistant Nylon105 belt and our anti-cut deflecting skin to boost confidence and durability on long rides and in any weather. And the 120 TPI casing in both versions reduces road vibration for long distance comfort over rougher terrain This tire is designed for hook-bead (crochet) rims that follow current E.T.R.T.O. standards. The tube-type version of this tire is not intended for use with hookless rims.

The Byway Road Plus tire allows riders to find comfort on remote gravel roads without being slowed down on the pavement required to reach them. Staying true to its road usage, a slick centerline borders angular hatching to keep everything smooth on sections of pavement. Intermediate, diamond-shaped peaks provide steadfast traction under power, while consistent and more substantial knobs extend down the side to protect it against ill-intentioned rocks or gashes while exploring new areas. - Road Plus TCS: Sealant optimized lightweight casing with folding TCS aramid bead and Dual Compound DNA rubber - SG2 bead-to-bead puncture protection provides improved air retention, and offers 80% more sidewall protection vs traditional single-ply tires - TCS Light Fast-Rolling: Lightweight casing with TCS aramid bead and Dual Compound DNA rubber (60a center/50a sides)

Nano 40 is built for speed. A nearly uninterrupted centerline provides swift efficiency on hardpack terrain while staggered outer knobs allow you to stay on the gas while hammering up chunky climbs or hanging on through loose gravel corners. The high-volume 40mm casing allows for lower tire pressures and a smoother ride while still reducing drag and rolling resistance. This makes for an all-out gravel destroyer that still appeases those clamoring for a truly big cyclocross tire. Everybody's irrefutable favorite, 'nough said. SG2 PUNCTURE PROTECTION: This tire is 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: - Minimal rolling resistance due to raised, consistent centerline tread. - Long, staggered knobs provide steadfast traction without cutting down on speed. - TCS Light/Fast Rolling versions of the Nano 40 tire provide ultimate tubeless reliability for gravel or cyclocross racing. - Race and Comp level tires are designed to provide optimal performance at a competitive weight but must be used with inner tubes. Race and Comp level tires are not tubeless compatible.

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. ZERO PLASTIC PACKAGING All new WTB tires are packaged using 100% recycled materials and zero plastic. Our engineers and marketing team are constantly working towards reducing the amount of packaging our products requiring, while still providing you with the necessary information to make an informed purchasing decision. It's no small task, but minimizing the total amount of packaging has become an integral part of product development. This results in simplistic packaging using more recycled materials and less zip ties. In the next few years, we're working to ensure 100% of WTB packaging goes in the recycling bins. Usage: Gravel / Monstercross Conditions: Dry to Wet / Hardpack to Loose Gravel - 650B: 440g - 700c: 460g
