Shockwave Karting releases new "short" wheel hubs ENGLEWOOD, CO - Shockwave Karting is please to announce its new line of short wheel hubs for racing karts. One problem with conventional hubs has been the mechanics ability to get a wrench on the pinch bolt with a wheel mounted. No more, with our angled pinch bolt, you no longer need to remove the wheel to adjust the track width. This is very helpful, particularly on the front where there is very limited space between the wheel and the brake disk.
