Bit Chip Covers are beyblade parts released as part of the bit chip.
Bit Chip Covers (ビットチップカバー Bitto Chippu Kabā) were initially attached to all Beyblades released under the Inital System (First Generation) and their purpose was to protect Bit-Chips from damage. However, as Bit-Chip Covers would frequently fall out in battle, Bit-Chips were lengthened during the implementation of the Spin Gear System. Bit-Chip Covers became obsolete as they became difficult to disengage with the new Bit-Chips. In addition to this, old Beyblades with Bit-Chip Covers, such as Master Dranzer, have now been changed to include the longer Bit-Chips in Japan.
