Hi! I'm glad to hear you're enjoying 100% runs. I've noticed the same problem with the Gamma variants those specific parts (Spike Dragon, Magne Weight Disk, NEO Left Spin Gear NMV, Sternclient, and Custom Grip Base) never seem to unlock beyond Beta, even after reaching level 70. It's odd, especially since they almost complete a Beyblade.

Your idea about unlocking parts by chatting with the girl in the lobby matches what I've observed, but those four parts appear to be missing a Gamma version altogether. It might be a deliberate design choice, or perhaps there's a hidden trigger that hasn't been discovered yet. Like you, I've had to do some personal digging, and information on this game is quite scarce.

If anyone else has managed to find those Gamma versions, I’d love to know how they did it! Keep up the research, and good luck with your runs!
