Looking for a replacement for cassette on Rad Rover?

Here's a picture of ZTTO cog (commonly sold on AliExpress)
You can replace it if you want to, that looks worn out anyways, but if you're talking about that specific tooth, that's not damaged.

Thank you Tempo, and many others. That is exactly what third gear looks like. I haven't inspected the others very closely. I see now that I don't need to go looking for a new set of drive gears, I think it's normal wear, just could use some cleaning, but then again it's a well maintained riden road bike not a show piece.

Thanks Timpo! I didn't know that either, but can surely understand why that gear might shift better once the purpose of that short gear tooth is explained.

Yep, I like that gear for stop lights with cross walks, on major multi-lane roads.
