Review on 🔧 37 Tooth Steel Rear Sprocket by JT Sprockets - JTR212.37 by Aaron Parish

Had to do a lot of digging on Amazon to find this but it is exactly what you are looking for when you need a Grom sprocket. Can't say for previous years but it fitted my new 2020 Grom 14t front wheel drive on the stock chain with no problems, performance is great, didn't get a chance to test it as it was raining when fitted. Don't let the photo in the item description fool you, it has the correct 4 hole pattern for fitting lucky rims!
