WTB's most dirt-centric Road Plus tire yet, the Byway Road Plus tire delivers supple plus-size traction and smooth riding characteristics farther into the dirt. 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 side knobs extend down the side to protect it against ill-intentioned rocks or gashes while exploring new areas. With the same overall diameter as a 700 x 30mm road tire, Road Plus provides the option for two different riding experiences with the same endurance road bike. 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. Usage: Road Conditions: Pavement / Mixed / Dirt - Weight: 535g - Compound: Dual DNA compound

Byway is for days of endless hardpack exploration and gravel grinding while also providing noticeable efficiency on any pavement linking it all together. A swiftly smooth centerline is paired to a textured intermediate section that provides a seamless transition onto small outer knobs for unwavering traction in loose dirt and gravel. Prominent outer knobs also extend down the sidewall to provide an additional level of defense from roadside unpleasantries of all shapes and sizes. Byway 34 is an identical replacement to the previously named Exposure 34 tire. We renamed the tire to create a uniform naming structure where all tires are named according to the tread pattern. SG2 PUNCTURE PROTECTION: Most sizes of this tire 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. Please refer to the charts below to determine which versions are available with SG2. - 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: - Smooth centerline for efficiency with diamond-shaped outer knobs for grip in the dirt. - High volume tire enables a comfortable ride. - Dual Compound rubber means a fast-rolling tire with great corning traction.

Volume, speed, and consistency. The Cross Boss’ even center tread shelf provides smooth and fast acceleration while more open side knobs help clear muck.

From singletrack to the circuit, the Cross Boss is here to bring it. Usage: Cyclocross Conditions: Dry to Damp / Hardpack to Loam - Weight: 400g - Compound: Dual DNA

It contains pure latex foam sealant and compressed air to quickly inflate and repair your tire so you can get on with your ride. Available in three sizes for varying tire volumes: - Road Racing: inflates 21-28-inch tubulars up to 94 psi and 700c clinchers up to 87 psi so you can ride, instead of walk to the closest pump and top off the tire to full pressure. - 75mL: Repairs and inflates low-volume MTB tires in less than a minute. - 100mL: Repairs and inflates meaty 27.5-inch tires and cross country 29-inch tires in less than a minute.

Whether in Gravel or Cyclocross, one thing is for certain: course conditions are constantly changing. When you roll up to the start line, be confident knowing that you have the performance advantage of the Terreno Mix all-conditions tread. At the heart of the design is a fast-rolling center ridge which is designed to minimize rolling resistance while still providing confident braking traction. Cornering and off-camber work are confidently handled by alternating open shoulder lugs. These lugs are shaped to allow a supple feel for pavement and hardpack surfaces, while still offering a solid effective edge for grass and loam terrain. If you are looking for that "one" tire to do it all, Terreno Mix is your choice! - For mixed terrain conditions - Open shoulder lugs for secure off-camber traction - Traditional tread profile for smooth transitions across a broad range of terrain - TNT tire bead

The ultimate wet weather weapon Many a battle has been lost due to a lack of preparation. In Gravel and Cyclocross racing, having the right tires is often the critical difference between winning and learning the hard way. When developing the Terreno Wet tread, we worked with the top athletes to gather their wish-list of performance traits that would make the ultimate wet weather weapon. Versatility was the common thread. It had to roll like a race tire, corner on rails, and be virtually clog-proof. A tall order by any measure. The final product is a tread that performs unlike any other. With the open alternating-lugged design and full siping, the Terreno Wet delivers pro performance in a range of soft terrain. - Alternating center ridge rolls fast and provides forward traction - Full knob siping keeps the tread flexible on slick surfaces - TNT tire bead
