Have you worked out exactly what they mean by the description, Hopper ?
I’m guessing that the 50mm is the outside diameter of the wheel.
...and that they are playing safe with the tolerance[!]

Translating the Chinglish can be a challenge. I think 50mm is the ID, the hole in the middle. Because a 90T Mod 1 gear (assuming that 1M in the description means Module 1) would be 92mm. So could be a bit large. But found this other one that is module .8 that is 72mm OD that would fit the space better LINK
Getting more exy at $50 but probably plenty more to chose from with a bit of searching around.
