The X Bone Chip is the replacement for the Bone Chip and it's predecessor the Bare Bones. It's slightly undersized with a 2.065" diameter and a 1.400" width (the same width as Dif-e-Yo's GTO). Its base weight is 61 grams, and adding the weight rings brings it up to 69 grams. The X Bone Chip is very similar to the Bone Chip with one little upgrade. It now has a CNC machine lip for the bearing to sit on rather than it sitting on the axle. The X Bone Chip includes a satin finish, extreme rim weights, and flush Dif-Pads to complement the smooth-playing Dif-e-Yo KonKave bearing. It comes packaged in a covered tin and includes extra Dif-Pads.
