  • Pretty good little sprocket
So I bought this for a motobike project, I used the bike berry alloy wheels and of course needed a drive sprocket for the pedals, this one looked pretty good and I got it, it’s done great for almost a hundred miles now,

Does everything you need a freewheel to do and for a great price. I use these on my SE bikes, Verde, Stolen, etc.. Always does the trick.
