While Challenge's legendary Grifo 33 tire is your best bet for course conditions that are all softer and looser, the company offers a more focused weapon in the form of the Fango 33 Clincher Tire, an open tubular designed specifically for conditions that are harder and drier, but still not quite hardpack or pavement like. The Fango's handmade 300 TPI Super Poly casing is lightweight and supple, providing responsive handling and a smooth ride quality. And although the Fango is a very lightweight tire, Challenge sandwiched its proprietary fabric between the tread and casing in order to increase its ability to thwart punctures. Called the PPS Puncture Protection System, this durable layer of material provides that added bit of protection to your race day tire setup. And while a tire's casing provides much of the ride comfort, Challenge also knows that its tread is equally important to the overall handling. Unlike most treads that have blocks of different sizes and spacing to accommodate a certain type of terrain, the Fangos have a center aisle of knobs that have been scooped out like a corn chip. The center scoop knob provides a greater number of contact points, while also effectively shedding mud. Meanwhile, the 33mm width provides you with ample grip, giving you the extra traction needed to launch that last minute attack. Another integral design characteristic that you'll notice about the Fango's tread is in the shape of the side knobs. These knobs have a special curve to them, allowing the shoulders to stay grippy while cutting through the muck. Confident cornering, especially in soft muddy conditions, could spell the difference between finishing and winning. The Challenge Fango 33 Clincher Tire is available in a 700c x 33mm size and in the color Blacktan. This tire weighs in around 355 grams, and ideally lends itself to lightly wet weather course conditions.
