Riptide "cracked ice" 96a pivot cups, for my blown out old Thunder Titanium 149's that I refuse to give up on. Just hit axel a tiny bit on the back truck, hopefully with these new pivot cups I'll be able to hit full axel in the back and maybe up front in my crook groove before needing new trucks.
Seriously though, yes they are expensive, but these Riptide pivot cups are worth their weight in gold.
