The Mavic Crossmax Quest Tires are great, jolly beasts of long running, flat resisting, surface gripping, off road tires. The handling benefits of the Crossmax's healthy volume are further complemented by the Contact Compound, which maintains grip in all weather conditions without sacrificing rolling efficiency or durability. After all, what use is an enduro tire's confident ride if its tread just burns out after a couple of weeks of riding The Crossmax Quests are also tubeless ready, so they can run at a lower pressure for added comfort without fear of the dreaded pinch flat. They're also more flat resistant when run as tubeless, and puncture fears are further assuaged by Guard construction. The Mavic Crossmax Tires are available in two sizes, 2. 35 and 2. 4in.
