Volume, speed, and consistency!
The Cross Boss's even center tread shelf provides smooth and fast acceleration while more open side knobs help clear muck. A rounded, high volume profile designed ground-up for tubeless usage provides plenty of room to modulate tire pressure while dual compound, Dual DNA rubber and defined cornering channels keep riders grinning for more turns. From single track to the circuit, the Cross Boss is here to bring it.
Light Fast Rolling
A supple, gram-conscious single ply carcass designed to be compliant and conform to trail objects while still providing a happy balance of low rotational weight and rugged reliability.
The "Fast Rolling" version comes with a centerline tread features a firmer rubber compound that boasts faster rolling and increased durability, while the side knobs are composed of softer, slower-rebounding rubber that improves control and grip.
TCS (Tubeless Compatible System)
TCS tires boast the ride benefits of a tubeless tire with the reduced weight of a non-UST tire. TCS tires combine WTB's lightweight race casing with a sealant tubeless, UST compliant bead. No problems with conventional rims. Those seeking extra durability can go with WTBs AM TCS or Team Issue tires for thicker casings.
TCS tires are the first sealant tubeless tires to receive Mavic UST® certification, which means a proven fit between sealant tubeless tire and rim. Say goodbye to air compressors, tire levers and pinch flats. Say hello to your full riding potential.
Weight supplement: manufacturer information
Note: Tubeless Ready tires require tubeless compatible rims/wheels, tubeless valves, tubeless rim tape and sealing fluid for tubeless mounting. Sealant fluid is not required for tubeless UST tires, but is recommended for increased puncture protection. Installation should only be carried out by qualified personnel.
