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.

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.

e-Martello hammers home the performance you expect, while extending your ride. Looking for the one tire to tackle a wide range of courses? This is the ticket. e-Martello features a 4C Graphene compound combined with a moto-inspired tread design and progressive width siping. This design provides for a progressive feel on the effective edge, allowing for that fine-touch tactile feel that riders expect. Whether shredding rocks, roots, or mixed terrain, e-Martello delivers.

The new Vittoria Mazza combines years of athlete input with cutting-edge tread technology, raising the bar on the mixed terrain Enduro tire category. Starting with a defined center tread, the Mazza uses deep siping in the direction of rotation, allowing the tire to roll fast while still opposing drift, especially in off-camber terrain. The stepped leading edge rolls like a ramp but digs in on climbs, making Mazza a top choice for both front and rear use. Substantial spacing was designed into the center tread to provide braking traction, while also accelerating mud clearing. Cornering on the Mazza is handled by Vittoria's trademark progressive sipe width technology, which gives a gummy inside effective edge without the instability that competitors experience on the outside of the tread. Simply put, bigger sipes flex more than smaller sipes. This unique siping pattern creates asymmetrical tread flex and translates into a predictable, confident, and communicative feel at the limit of cornering. Mazza's generous tread depth claws into a range of terrain and is stabilized with Vittoria's proprietary 4C compound layering process. Four separate Graphene 2.0 compounds are layered, allowing the surface of the tread to remain tacky while the base remains planted. This ensures each effective edge is kept in place under high cornering and braking loads, leading to reduced rolling resistance and increased wear life. The bar has been raised. - Aggressive profile with ample sipe spacing for mixed terrain - Progressive sipe width for tactile grip on rocks and roots - Stepped leading-edge center-tread maintains speed and delivers climbing traction

The ultimate touring tire, made for roads, tracks and trails of all continents. The tread pays homage to its legendary Marathon XR predecessor. Construction and compounding are naturally the very latest Schwalbe Evo technology. TravelStar compound for the best handling characteristics, Double Defense technology makes it light, but with an extremely robust construction. The world is round. Ride it.

The Air-Liner is a high-quality polymer insert that replaces a portion of the air volume in the tire. This trait, combined with the shape, provides a tunable system that enhances your ride performance. The Air-Liner sidesteps the traditional compromise of stability vs. grip and allows your tires to remain stable, grippy, and controlled, even at low pressures. The Air-Liner is designed using a round cross-section with channels on the top and bottom. The top channel provides room for the tunable air chamber that sits directly beneath the tire tread. Upon impact, the corner edges of the channel flex first. This allows the tread to remain flexible, which increases traction without sacrificing impact resistance. The bottom channel allows for easy fine-tuning of the air chamber and allows for full compatibility of all valve core styles. The round cross-section shape mimics the natural shape of the tire and supports a greater contact area within the sidewalls of the tire casing. Side-to-side tire stability is increased, yet the tread remains soft and grippy. This improves cornering, climbing, and braking performance. - Protection: Both wheel and tire are protected by the Air-Liner insert. By cushioning impacts from within the tire, your expensive rim remains protected while eliminating flats caused by rim-strike impacts. - Control: The Air-Liner insert replaces air volume in the tire. The reduced air volume allows the tire to compress and rebound in a more controlled manner compared to standard tubeless systems. - Performance: Side-to-side tire stability is increased, yet the tread remains soft and grippy. This improves cornering, climbing, and braking performance. - Durability: This highly durable polymer material has been tested to a projected life of 2000 hours under normal riding, or 1 full hour of run-flat downhill use under a typical rider. - Air-Liner increases control, durability, performance, and protection of both tire and wheel. - Sold individually (single tire). Compatibility - Small: 1.9 – 2.25-inch wide tires - Medium: 2.25 – 2.5-inch wide tires - Large: 2.5 – 2.7-inch wide tires - X-Large: 2.7 – 4.0-inch wide tires
