If you need the perfect tire from the 60s look at the Metzeler Block Cs. A traditional Metzeler pattern but made with modern compounds and methods. As in the past the tire is bi-directional and can be used in a front or rear application. Available in a tube type construction only and must be used with a Metzeler tube on a tube type rim. Designed for vintage bikes like Sportsters, 60 &70 Japanese and English bikes, and of course the famous BMW slash series bikes
