Nano is built for speed. The 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 smooths out jarring gravel while also 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.

Uninterrupted Center Tread
You'll be surprised at how fast the Nano rolls for a tire with such tall knobs. The magic comes from the consistent spacing of knob groupings to allow the tread to glide across the surface of hardpack terrain.
While the consistent knob spacing makes the Nano incredibly fast and efficient, the height of the knobs provide traction by digging while pedaling or braking on loose surfaces. This ensures the Nano is always fast but also confident when you need it to be.
Flying V Pattern
Inspired by birds that fly in a V formation to improve efficiency, all knobs on the Nano channel speed through a repeated V pattern to transfer every watt of your energy from one knob to the next with as little energy loss as possible.
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.
