This was literally impossible to fit onto my 22mm spindle. It was barley too small
Hello, Thanks for the question! - Spline drives can be a pain to fit, due to the way they are designed they need to allow no movement when fitted to ensure instant engagement. Make sure you are using lots of grease, the splines on the axle and the sprocket are clean and you are fitting it straight on to the splines. Feel free to contact us for further help, we will be glad to!
