Pirelli's first foray into the Bicycle tire market, the PZero strikes the fine balance between rolling resistance and cornering grip. The supple casing and grippy rubber compound keep you stuck to the ground while railing corners while not feeling draggy when drilling it in straight lines, as some other super supple tires might. The PZero is our pick for an all-around tire, ready to tackle crits or a long day in the saddle!
