For the off-camber sections that are sure to be found on every good cyclocross course, the Locust CX has squared shoulder lugs to provide the best traction and allow you to take the line you want. Note: Have you checked the ETRTO of the tyre your replacing matches this one It should read xx-520 (xx is the width) - THESE TYRES DO NOT FIT ISLABIKE, FROG or similat Hybrid 24″ BIKES.
