While plus size tires are making waves on the enduro circuit, the speed enthusiast in us still appreciates the value of a tire in the smaller but still plush 2. 3in range. The 29in Crossmax Quest Tire fits that bill, mating Mavic's new hard wearing, all weather X mix Quest compound with a tubeless design that further reduces rotational mass. 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.
