Hey guys. Have a question. We have 2 Phatmoto 2020 Rovers. My husband needs a jack shaft chain for his but I'm not sure what dimensions or specks to look for when ordering. I've ordered several components for our bikes that haven't worked out so I'd really like to be sure about fitting before I order, and I'm not ordering from gasbikes.net anymore. Tia Yolie
 
What size sprockets do you have on the jack shaft?

If you don’t have a caliper, ya need to get one.

First, google chain dimensions, then measure your sprocket dimensions.

Pay special attention to the thickness of the teeth.

Most sprockets and chains have 1/2” pitch, but different widths between the links.

Good luck, Tia.
 
Very often there will be a number stamped on the flat surface of your JS sprocket. More than likley it will be 35, 40 or 41. That will be the chain size, then you just must decide what length you need. Good Luck
