Bones Street Tech Formula is specifically designed for higher rebound and to be more resilient against flatspots. Made from the highest grade components, Bones STF wheels last longer and respond highly.

Shore Durometer B Scale is used on the STF wheels as it reads the hardness of the wheel more accurately, but starts 20 points lower. So for wheels above 95A, the B scale gives you a more accurate measurement of the wheel and it’s responsiveness.
