Consider what you consider.
If its multiple-world-championship-winning tread pattern doesn't grab your attention, then the incredibly smooth and tough 300tpi casing should do the trick, right? Or the classic tan sidewall? Or the legendary durability? If none of these things convinces you that the Challenge Grifo 33 Tubular Tire is worth serious consideration this season, then you might want to give serious consideration to your ability to give serious consideration.
The hand-made Grifo 33 Tubular Tire has a highly puncture-resistant and lightweight Super Poly casing. With 300 threads per inch, you can expect a remarkably supple ride. It's a difference that you'll feel the first time out. Additionally, the Grifo tread is hand-glued onto the casing when the casing is already mounted and inflated on a wheel. As a result, the tread isn't put under tension when you inflate the tire on your wheel, and that lack of tension leads to a lower rolling-resistance, added grip, and increased comfort.
A superior all-around 'cross tire must have tread that provides a harmonious balance between low rolling-resistance and grip, and the Grifo's tread is world-renowned for striking that balance perfectly. The knobs are relatively low-profile, but they're effectively spaced in order to shed mud and to provide excellent traction. Simply put, the Grifo Cross rolls fast, it bites into soft ground, and it corners as if it's on rails.
The Challenge Grifo Cross Tubular Tire is available in a 700c x 33mm size and in the color Black/tan. Each tire weighs in around 415 grams. Please note that Challenge gave this tire a latex inner tube to save as much weight and roll as fast as possible. Because latex is more porous than butyl rubber, you'll have to pump it up a bit before your rides.
