SK8KINGS Turbo Wheels - Aluminium Core 70mm / 82a. Sk8Kings is proud to continue the roll-out of our Turbo series wheel line. Following years of R&D and extensive testing by our team riders - the production version Aluminium Core Turbos have been a huge success with traction, speed and predictable slide control. The Turbo Aluminium Core Wheels feature a CNC-machined aluminium core - for precision bearing fit and superior wheel alignment through critical turns. This Turbo urethane formula - far exceeds the traction capabilities of any wheel we've ever tested - allowing the rider to take more aggressive lines while maximising speed and roll. Turbo wheels are an excellent choice for all racing disciplines, long distance pumping, carving/cruising -- made to handle speed with great traction and controlled sliding when needed. Turbo Wheels - like all Sk8Kings skateboard gear - are made in So Cal -- USA Proud!
