All Campagnolo wheels are constructed to meet the highest standards of resistance and durability. If the total weight of yourself, your bicycle and any accessories exceeds 120 kg/265 lbs it is recommended not to use these wheels. Non compliance with this warning can damage the product irreversibly. Check with your mechanic to discuss whether the wheels you selected are suitable for your use, and to determine the frequency of inspections. Using tires with a larger diameter and a frame that respects the standards will help to increase the lifetime of the wheels.
