Whether you’re exploring the countryside back roads at the weekend or taking part in a cyclocross event, this versatile gravel bike tire is engineered for performance. It features a raised, consistent centerline tread for minimal rolling resistance, while its long staggered knobs provide excellent traction without cutting down on speed.
Tubeless Ready Cyclocross Tire
Nano 40 is built for speed. A 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 allows for lower tire pressures and a smoother ride while still reducing drag and rolling resistance. This makes for an all-out gravel destroyer that still appeases those clamoring for a truly big cyclocross tire. TCS Light/Fast Rolling versions of the Nano 40 tire (this version) provide ultimate tubeless reliability for gravel or cyclocross racing.
SG2 Puncture Protection
These tires are available with WTB’s 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.
**Dual DNA Compound:**Two rubber compounds. The centerline tread features a firmer rubber compound that rolls fast and resists tread wear while the side knobs are composed of softer, slower-rebounding rubber to improve control and grip. All Dual DNA tires fall within the Fast Rolling category.
**SG2 Puncture Protection:**Nylon fibers have a flat profile, which reduces the amount of rubber needed to fill the gaps between fibers and minimizes weight. SG2 was specifically designed to be a puncture protection layer, but it also improves air retention and eliminates seeping at the sidewall.
Tire Pressure Information: WTB’s tire pressure recommendations have changed over time due to further developments in technology. Riders may always reference the markings on their tires for allowed pressures ranges, but WTB calculate pressure recommendations based on an average rider weight of 160-180 lbs and suggest increasing the minimum recommended pressure by 2-3psi for every additional 10 lbs of rider weight. Never exceed the maximum tire pressure marked on a tire.
