The Tacx trainer tires have been developed specifically for riding indoors on bike trainers. The special rubber minimizes the risk of overheating, slipping, and wear and tear. They are also quieter than regular rear tires on both road and mountain bikes. Tacx trainer tires are not suitable for outside riding.

The Product that Started a Tubeless Revolution Inside this simple bottle is a product that changed cycling. Today's tubeless systems rely on the lighter, more reliable, self-sealing performance of Stan's Tire Sealant. Just two ounces of Stan's in a converted standard tire or tubeless tire can repair punctures up to 1/4-inch almost instantly to keep you rolling. Longer-lasting Stan's Tire Sealant is formulated to stay liquid in tires with even thin casings for up to seven months. Arid conditions require more frequent monitoring of sealant levels, but anti-freezing agents in our special formula allow Stan's Tire Sealant to be used in temperatures as cold as -30° F. One quart will convert up to 16 tires. - First choice of riders around the world for tubeless conversion and flat prevention - Seals punctures up to 1/4-inch (6.5mm) quickly - Stays liquid 2-7 months for long-lasting protection - Premium low-viscosity formula resists freezing to work in environments as cold as -30° F (-34° C) - Natural materials, safe for the environment - Can be injected through valve stems with removable cores compatible with tubes and tubular tires

Rubber has always been a serious topic of discussion at WeThePeople. Not only is it the connecting point between your bike and what you’re riding, it also makes a huge difference as to how your bike feels. After the success of the Grippin' and Feelin' tires, WTP wanted a fresh new design based on the needs of the modern street rider. After a long process of testing compounds and refining the tread design, they came up with something quite special. The Stickin’ tire is the successful end result of over a year of hard work. It uses a specially designed shape and specific rubber compound that allows it to stick to nearly anything, yet enable you to grind endlessly without getting your tire stuck on the side of the rail or ledge. This 'street slick' beast was designed to grind and slide like nothing else.

The All Terrain is always up for adventure. From long-distance touring to light-duty offroading, this tire offers impeccable handling that won't let you down.

Judge is our rowdiest rear tire…for loose, sketchy descents. Centerline knob groups alternate between long and wide to pair hard braking traction with the rolling efficiency you demand of a rear tire. Burly outer knobs provide the support needed to keep them digging while slapping berms or spraying loam. We optimized the Judge for wide rims to provide a flatter tire profile that makes the outer knobs easy to find while cornering. The Judge keeps everything in order, whether dry and loose or wet and sloppy. - Massive side knobs and a beefy overall design that grabs in every direction - Designing tires around wide rims provides additional support while also bolstering sidewall protection through ample tread overhang - Ideally paired with a Vigilante 2.50 or Verdict 2.50 on the front

Judge with SG1 is our rowdiest and toughest rear-focused tire. Centerline knobs alternate between long and wide to provide the hard braking traction and efficiency required of a rear tire. Burly outer knobs provide support and dig in to keep you glued threw off-camber corners. Judge features a flatter tire profile than most other tires, which makes it easier to reach the outer knobs when cornering. The Judge keeps everything in order, whether dry and loose or wet and sloppy. SG1 puncture protection runs under the tread cap and has extended bead protection. Big Knobs, Big Sipes Massive knobs in every area of the tread prove that the Judge prioritzes traction above all else. Long, thick knobs till through rocky terrain without folding under heavy cornering forces. Each knob features full-length siping to essentially double the amount of knob edges contacting the trail. Flat-Top Profile The side-to-side tread arc of the Judge is "flatter" than most tires, which results in the side knobs engaging sooner while cornering compared to a tire with a rounder profile. This allows the side knobs to dig into the terrain quicker and deeper, which improves cornering traction on loose, off-camber trails. Rear-Focused Design Judge features wide, blocky knobs that maximize braking traction and improve the longevity of the tire. The side knobs overhang the sidewall of the tire to protect it from slashes while you're steering with the rear. We suggest pairing the Judge with a Verdict 2.5 or Vigilante 2.5 on the front. 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.

Light as a Feather The true 2.4” tire measures 62mm ( on an i30 rim) and weighs a scant 732g (120tpi black with SG protection). Cross-country racers want a Goldilocks mix of characteristics in their gear: speed without sketchiness, suppleness without delicacy, and tank-like grip without tank-like weight. For tires, it’s often been a matter of sacrificing one characteristic for another. Not anymore. The new WTB Macro 2.4” tire shatters that trend. It rolls fast, digs into the turns with precision, and deflects even the sharpest rocks thanks to its SG puncture protection. Puncture Protection Galore Part of the secret sauce is WTB’s SG puncture protection, made of a rubberized nylon fabric that protects the sidewalls without compromising suppleness. The use of flat fibers in the SG barrier reduces weight compared to traditional round fibers and allows WTB to tune the ride characteristics even further. Short, Efficient Knobs Macro’s centerline is made up of small, tightly spaced knobs that pack a punch, delivering unmatched speed and braking traction. When you lean into a turn, the wider spacing and raised outer knobs provide steadfast grip when you need it most. Pair this dynamic tread with a wide, rounded profile and the ability to run lower air pressures, and you get an incredibly capable tire that delivers a perfectly smooth transition as you pitch in and rail through turns.

Center knobs feature a medium durometer compound to provide traction and durability without sacrificing rolling efficiency, while outer knobs feature the softest compound for maximum grip and slow rebound characteristics. TCS Light Casing TCS Light tires feature one layer of casing to minimize rotational weight while simultaneously increasing the overall liveliness of a tire. Using a single layer of casing results in a gram-conscious tire that better conforms to the trail and increases traction without the need for excessive knob heights that would reduce efficiency. Many of our TCS Light mountain tires feature Slash Guard technology, which provides a protective nylon insert spanning the entire sidewall to provide extra puncture protection without the weight of a dual ply casing. SG Puncture Protection WTB’s SG tires start at the material level, specifically formulated for superior sidewall protection and increased air retention in high-pressure tires. Sidewall Protection: The extra layer defends most exposed areas of the tire and improves air retention for high-pressure tires. 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.

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.

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.
