Hey Fellas. I went to put the chain on my Powell today and I bought the wrong size from OldMiniBikes a while back. :facepalm: I had only used #35 before and the Powell chain was bigger, so I told myself, "naturally it must be 41". Nope, I'm still learnin'. So Powell bros, what size chain do I need to find for my D-series? ...and where do you purchase it? Thanks.
