For ten years now, Challenge brand tires have been enriching the cyclocross market. The Italian company's most famous model is undoubtedly the Grifo , a tire on which world championship titles have already been won.
The Challenge Grifo comes in two sizes, the Grifo 32 and the Grifo 33 , as well as in two color options: white with a black sidewall and black with a brown sidewall. We tested the white version in the 33-inch width. This all-rounder from the Italian manufacturer is made from a Super Poly material blend and has a casing density of 300 TPI. The tire features Challenge's proprietary Puncture Protection System in the rolling area . The tread pattern is characterized by circular knobs on the edge and arrow-shaped knobs in the center.
The Grifo 33 is relatively easy to mount and align on the rims for a tubular tire, yet it sits securely in the rim bed. We inflated it to between 1,8 and 2,3 bar, depending on the ground conditions and weather. In use, the tire proved to be a fast companion. Combined with the 46mm deep carbon rims, it offers both pleasant control and tracking stability. It responds promptly and smoothly to acceleration, although on very dry surfaces, the Grifo 32 would probably be a better choice. The open tread pattern is very self-cleaning. Overall, thanks to its shallow but well-designed knobs, this puncture-resistant tire can be described as a nimble grass tire that also performs well on damp soil and loose, sandy sections. However, for truly muddy conditions, it's advisable to switch to a tire with a more aggressive tread pattern.
//Conclusion
The Challenge Grifo 33 is a true all-rounder, a reliable choice in most conditions. It doesn't need to fear comparisons with the market leaders in cyclocross tubular tires, Dugast and FMB. On the contrary, its price advantage makes it a serious competitor.
