About Challenge
Since 1985, Challenge has been producing bike tyres in various versions, colours, sizes and models. The name Challenge already suggests what these tyres are made for: to help you in all challenges.
The Italian company places great emphasis on the fact that many of its tyre models were developed together with professional riders. Many of the open tubular tyres are manufactured using the same processes and materials as the tubular tyres. Combined with a latex inner tube, Open Tubular tyres offer a driving quality very similar to that of a tubular tyre: excellent grip, ideal for cornering, rolling resistance and comfort.
