Challenge tires have been enriching the cyclocross market for ten years now. The most famous model of the Italians is certainly the Tap be, a tire on which world championship honors have already been won.
The challenge Tap comes in two styles, as Griffo 32 and as a Griffo 33, as well as in two color variants, white with a black wall and black with a brown wall. We used the white version with a width of 33. The all-rounder from the Italians consists of a super polymaterial mix together and has a carcass density of 300TPI. In the rolling area, the tire is Challenge's own Puncture Protection System fitted. The profile is characterized by circular nubs on the edge and arrow-shaped nubs in the middle.
The Griffo 33 is relatively easy to pull onto the rims and align for a tubular tire, but still sits firmly in the rim bed. Depending on the soil and weather conditions, we filled it with 1,8 to 2,3. In use, the tire shows itself to be a fast companion. In combination with the 46 millimeter high carbon rims, it offers comfortable control and directional stability at the same time. It reacts promptly and easily when you step on it, although on very dry soil you are more likely to Griffo 32 should change. The Self-cleaning of the open profile works very well. Overall, the puncture-proof tire can be characterized as a nimble lawn tire due to its flat but well thought-out knobs, which also cuts a fine figure on damp soil and loose sandy sections. If the ground is really muddy, however, it is advisable to switch to a tire with a coarser profile.
//Conclusion
The challenge Griffo 33 is a thoroughbred all-rounder, one that is a dependable choice in most conditions. There is no need to fear comparisons with the models from the market leaders in the field of cyclocross tubular tires, Dugast and FMB. On the contrary: Due to its price advantage, it is even a serious opponent for them.
