The best tubeless ready tire Specialized or any other brand has introduced to the market. Bike Cycles stocks these tires and we like setting them up with Specialized brand tubeless sealant. We also love Orange Seal sealant but the new Specialized sealant works great with these higher pressure tires. This tire has Black Belt technology which is a puncture resistant band around the tire to make them the best all around tire on the market. They can be run just as easily with a tube.
