The Contact is the jack-of-all-trades amongst city and trekking tyres. Its tread design is based upon the principles of bionics. A uniform center tread/belt assembly ensures a smooth and speedy ride on the road. Flexible shoulder lugs and fine sipes guarantee grip in curves and on loose surfaces. The overall tyre construction rounds off the overall high quality. The ultra fine carcass fabric reduces the rolling resistance while providing a noticeably more comfortable ride. 3 plies/ total 180 tpi / SafetySystem Breaker dimension:26x1.75 , weight: 570g, recommended inflation psi:45, max inflation psi:58
