Yup checked all that and found rear sprocket to be slightly out. Put one of my old but not too worn Rentals on and it has all but disappeared.

Assume you are talking tight spot like a chain that has a stretched area and then had the wheel pulled back all the way.

Chain is all good. Sprockets even at new are obviously not the best. Thought when i brought it i had chosen a reasonably good brand too. But there ya go, even the bet can cock it up.

You'll have us all converting to shaft drives...until you solved it by letting us know about the dodgy sprocket
