Jake nailed it. MOI=Moment of Inertia

Yep, tires dominate but my post was more to try to figure out how much benefit you get out of a 10lbs. one piece wheel vs. a 13lbs one piece wheel vs. a 10lbs. 2-3 piece wheel.



AG, You know that question was way over my head. I am doing good just to get my feet on the pedals and hands on the wheel.

BTW, I need you to look at his video setup I have, if you come to MSR. I need tech advice.

With "wintry mix" at a 60% chance on Saturday for Cresson, and 40% on Sunday, I seriously doubt there will be any racing going on this weekend Mac.

You need to come down to the kart challenge at Iron Rock instead to get your racing fix...shoot me an e-mail with your video question needs if you want.
