Who knew wheel balancing could be so easy? I'm chasing my car and have lost some weight and also the weight has shifted (the front wheels get very hot on the track!) The bike ride to the store is quite tiring and expensive so I thought I'd give it a try afterwards. some research. Works perfectly! It's easy to set up and align, then carefully center the wheel on the cone, add weight until balanced and you're done. Be sure to lubricate the tip and sliders and do not rotate the cone on the tip. When you hit the track, grab some 3M high-temp aluminum foil tape and cover your weights and you'll be fine. Enjoy.
