So this world just doesn't use rubber at all? Impact Drake being shown like some Eldritch Magic when all they did was put rubber on it?
This series really is a comedy if you're not willing to suspend your disbelief.
Rubber only use for the bit. No one use the rubber for the blade. It seems weird because in this world, beyblade is known for ages but no one ever use the rubber at the blade. Idk about B4 regulation and standarization because all the bey that compete at X Tower need to pass B4 inspection. Now, let's see if this Impact Drake will pass B4 inspection or not. Idk the author will put about this at next chapter or not, but if Impact Drake can compete at X Tower, that means Impact Drake pass B4 inspection.
And knowing Impact Drake developed at BEYSA who affiliated with Shiroboshi Dojo, it still make sense. Because at previous chapter is revealed that Shiroboshi blader are "isolated" from competing at X Tower, and in this chapter Tenka caught the glimpse of bey's blueprint. Soo, this innovation seems isolated too and didn't make to the public.
But still, if we think realisticly, this is all about Takara Tomy selling their toy 🤣 This is just like marketing strategy or something like that.
