The Adventure Tech offers a fast-rolling center that transitions to a mild side tread for City/Touring performance in a range of conditions. The e-bike-compliant Graphene compound rolls fast and extends battery life when used on an e-bike. A reflective sidewall stripe increases your visibility for oncoming motorists, while the Solid Shielding puncture protection layer makes punctures a thing of the past. As with all Vittoria Tech Series tires, the mix of performance and durability add up to a great value! - Fast-rolling center, transitioning to a mild side tread - Graphene compound is Regulation-compliant for e-bike use - Wire bead

Unstoppable on ups. Relentless on descents Syerra has been developed to satisfy the needs of the emerging Down Country segment, raising the limit of what a XC tire can do. Vittoria engineers combined in a single product Speed and Rolling Performance – typical features of the XC segment – together with High Grip and Resistance – traits of the Trail Segment. The result is a light and fast product which allow to have fun also when tackling burlier descents and gnarlier terrain. - High durability and maximum speed thanks to Graphene and 4 different kind of compounds - Outstanding grip performance: tread design engineered for multiple conditions - Safety and sidewall protection ensured by the Anti-Pinch Flat (APF) sidewall insert

Speed and traction Aggressive file tread, or super low-profile knob design? The Terreno Dry bridges the gap between file treads, and traditional all-conditions treads. The key to this is the unique angled “fish scale” design, that allows the center tread to roll extremely fast, yet offer traction when loaded in cornering and braking. Add the transitional height mid and side tread, and the Terreno Dry transitions as smoothly as it rolls. From gravel grinding to medium conditions cross racing, the Terreno Dry offers consistent performance.

Corsa inspired tread Corsa inspired tread design, for paved surfaces and hard-packed gravel. The smooth Corsa inspired center rolls fast, while the side tread “scales” provide durable bite when cornering and braking.

The Corsa Control tackles greasy cobbles and rough roads with all the confidence of the classic Corsa. Sharing the same 320 TPI Corespun-K reinforced casing and technical 4C Graphene compound technology, the Corsa Control adds a textured shoulder tread to the mix. This chevron tread pattern adds dynamic performance to the Corsa Control tread, allowing for increased grip on slippery surfaces as well as added durability. - Corsa level confidence for rough roads - 4 separate Graphene compounds deliver speed, suppleness, durability, and reliability - Reinforced Corespun-K casing for increased sidewall protection

Your tires are the only thing connecting you to the road or trail, and having optimal tire pressure can have more impact on ride comfort than both frame and wheel choice combined. But finding the right tire pressure requires trial and error. TyreWiz for Moto is the first-of-its-kind tire pressure sensor for Zipp 3Zero Moto wheels and takes the guesswork out of finding that optimal tire pressure. Lightweight and durable, TyreWiz adds only 10 grams to your tires. With an IPX7 waterproof and dustproof rating, you can confidently ride on any type of trail and know that your tire pressure sensor will keep going strong. TyreWiz reports data with +/-2% accuracy at a resolution of .1 PSI; vastly more accurate than any tire pump on the market. TyreWiz monitors the air pressure in real-time and relays the data to a cycling computer or a smartphone. That information is relayed to the SRAM AXS app and delivers personalized recommendations and pressure alerts. TyreWiz gives riders access to highly accurate, real-time tire pressure data to make decisions that can affect rolling resistance, traction, tire wear, and rider comfort. Features - Data reported with +/- 2% accuracy at .1 PSI resolution. - Only compatible with Zipp 3ZERO Moto wheels. - Inexpensive, user-replaceable CR1632 battery lasts for 300 hours. - IPX7 dustproof/waterproof rating.
