Tubular tyre for training and touring. Exceptional grip in both wet and dry weather. The Curve Control System guarantees durability and an exceptional ride quality, even in corners. TriComp Technology. A thick weave polyamide layer embedded in the central overlap of the highly flexible casing. This is used in practically all our race tyres, the Bull Lock and the Excellent line of our Tour/Trek/City range. The specific tread and side wall compound guarantee the best grip and lowest rolling resistance in all weather conditions. The tread compound is highly wear-resistant and smooth running, while the softer compound across the tyre shoulder ensures optimal grip in dry and wet weather. The curvature of a tyre determines its steering behaviour, which is particularly important in corners. The Curve Control System ensures that the tyre keeps its curved shape longer. Combined with the unique characteristics of our TriComp technology, this allows corners to be taken at higher speeds, even in wet weather. In other words, the Curve Control System translates into tangible benefits in corners.
