Cross Boss delivers the speed and consistency that keeps riders grinning for more turns, more sprints, and most importantly, more laps. Tightly spaced center knobs minimize rolling resistance while stepped intermediated knobs and widely spaced outer knobs help clear muck when the course turns into a slip 'n slide. From gravel pursuits to the cyclorcoss circuit, the Cross Boss is here to bring it.

Tightly spaced center knobs minimize rolling resistance by allowing the tire to glide on the surface of the terrain, then dig in while pedaling or braking.
Wide 35mm Casing
The perfect width for keeping things skinny while still keeping them cross. The Cross Boss' 35mm width helps provide all the confidence and traction cyclocross racers need while staying within the constraints of all reasonable racing regulations.
Alternating intermediate knob heights and widely spaced outer knobs help clear muck throughout the sloppiest days on course.
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.
TCS Light Casing
TCS Light tubeless tires feature one layer of casing to minimize rotational weight while simultaneously increasing the overall liveliness of a tire. Using a single layer of casing results in a gram-conscious tire that better conforms to any terrain and increases traction without the need for excessive knob heights that would reduce efficiency. Many of our TCS Light gravel tires feature SG2, which 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.
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.
