A few days ago I ordered some Riptide Pivot cups for my Caliber II's. I wasn't paying attention much to the checkout and accidentally ordered two sets of them. I swapped out the stock pivot cups and threw in the Riptides and this is what happens. Its a bit hard to see, but the trucks are slanted. When going into a carve they have ABSOLUTELY NO return to center. They just stay dead with no rebound what so ever. I thought the first set was just a dud and I tried to second set I had. SAME EXACT THING. At that point I thought it was my trucks for some reason so I asked my friend to try them on his trucks. Same exact problem. I even tried lubing them up just a little, it sorta worked for a day or two but after that back to the same thing. I never once had a problem with Riptide Pivot cups on any of my other trucks. But I'm going to have to say that they really fucked up with Caliber II's.
