The latest generation of the World-Cup-proven intermediate tire, the Butcher BLCK DMND 2Bliss Ready, receives sawtooth faces on the tread blocks to increase stability under load and provide additional biting edges. This, in turn, improves rolling speed as well as control under hard braking and cornering. Meanwhile, our proprietary GRIPTON compound improves high-frequency damping, attaching the tire to the ground better on both small bumps and rough sections. The low frequencies of the rolling tire deflections pass through unfiltered, leaving no energy absorbed, keeping the speed high. Once you ride the Butcher, you'll never want another tire for your gravity excursions. The new BLCK DMND casing strikes the balance between suppleness and extreme pinch flat protection. In order to descend all-out, you need as much traction as possible—the tire needs to conform and hold on to the ground, but also protect from pinch flats. In order for this to happen, only the treaded part of the tire needs to conform, grip, and dampen, while the tire base offers stability and support for steering inputs. - Casing: Center Overlap, Flip Up and Rubber Apex - Bead: Foldable - Butyl wrapped bead = 2Bliss Ready - Compound: GRIPTON - 27.5 x 2.3", psi 25-50 - 27.5 x 2.6", psi 20-40 - 27.5 x 2.8", psi 15-30

The Butcher GRID GRAVITY 2Bliss Ready T9 is the perfect choice for trail and gravity riders. Ramped and siped center tread blocks provide strong traction and accurate steering, while the shoulder knobs offer a continuous biting edge for railing through fast corners.

Building on this solid base, the high-dampening T9 GRIPTON compound rebounds slowly to grip and stick to the ground for total traction and control. - 650Bx2.3", psi 25-50, approximate weight 1050g - 650Bx2.6", psi 20-40, approximate weight 1200g - Bead: Foldable - Butyl wrapped bead = 2Bliss Ready - Casing: 60 TPI, Dual-Ply - Compound: GRIPTON T9

The latest generation of the World-Cup-proven intermediate tire, the Butcher GRID TRAIL 2Bliss Ready, receives an entirely new tread pattern. Wider shoulder knobs better support load under hard cornering, while the biting edges of the shoulder knobs are moved further inside. The center blocks have been staggered and spaced better for a smoother transition when leaning the bike over. Our new GRID TRAIL casing is stiffer, delivering better handling at lower pressures, all while increasing pinch flat protection by 15% and puncture protection by 30%.

The world’s fastest riders are always hungry for more traction. So when Loïc Bruni, Finn Iles, and Chris Grice from the Gravity team reached out to us to develop a mountain bike tire to tame World Cup Downhill tracks, we cooked up something that will satisfy even the most aggressive appetites. We completely redesigned the Cannibal tread pattern, integrating our super-sticky GRIPTON T9 compound with a high-volume casing that brings superior control to any terrain. Staggered shoulder blocks maximize cornering stability, and large center braking blocks bite aggressively into the ground. Engineered to the design specifications of our riders, the Cannibal balances weight and durability with GRID Gravity casing for Enduro, Downhill, and Park riding. The Cannibal delivers the unbeatable combination of grip, confidence, and control to devour any track. - High-volume casing and staggered shoulder blocks for predictable high-speed cornering. - Re-designed center knobs and siping form strong surface connections. - Wide braking edges and massive center blocks cut in for maximum deceleration. - GRIPTON T9 compound reduces terrain-induced chatter, enhancing confidence at warp speeds. - Compliant and adaptable GRID GRAVITY 2-ply casing construction is ideal for Enduro, Park, and Downhill riding. - 2Bliss Ready technology protects against pinch flats, cuts, and punctures.

The Eliminator still has the bite of a DH tire but also brings the manners to handle well on hardpacked trails. These characteristics also work well for trail e-bikes, too—combining the traction needed to stay in control on the trail with neutral handling on fire roads. Our new GRID TRAIL casing is stiffer, delivering better handling at lower pleasures—all while increasing pinch flat protection by 15% and puncture protection by 30%. - Casing: Additional bead-to-bead protection for exceptional durability, plus sidewall stiffness stability - Bead: Foldable - Butyl wrapped bead = 2Bliss Ready - Compound: GRIPTON - 27.5 x 2.6" - PSI range: 20-40 - Approximate weight: 850g

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 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.
