Whether your frame doesn't have the clearance or you're not a fan of how they dilute trail feel, we understand if you're not jazzed on the new plus tire radness. The 27. 5in Crossmax Quest Tire fits that bill, mating Mavic's new hard wearing, all weather X mix Quest compound with a tubeless design that adds plushness without the unwieldy bulk of 3in tires. X mix mixes a hard center rolling strip with slightly softer shoulders to increase cornering confidence but maintain a myopic focus on low rolling resistance. The casing is reinforced with Guard , a single ply armor that adds puncture protection without undue weight.
