Kryptonics has been making skateboards since 1965, and stands behind every product 100%. We do not skip any process during manufacturing to insure that all skateboards are made the proper way. If any component is made not to our standards, we change it on the spot. Our wheels helped revolutionize the skateboard industry, and continue to do so. Our special urethane chemists continue to shape and create the best wheels on the market today.
