That's a pretty impolite thing to say, isn't it?\r\n\r\nComes in three distinct flavors: one with a single bearing smack dab in the middle and two featuring four bearing designs each.\r\n\r\nBoasts 22mm diameter bearings that might require some light sanding to fit snugly. If you're opting for the open design, be sure to secure those bearings with glue or they'll likely fly out.
