The races are the angled surface that the bearings ride on. They can be removed if they are scratched/gouged.
I should have went and helped ya with those. I sure didn't help the numbers that day, you lost a knife, the bearings went kaput, and you burned your gas and all I did was get a ride in a nice boat.

F YEAH I WANT A BEER!
