I have changed my early (April 2012) sprocket for a lightweight one made of exotic steel. You also need to change to the later type (black) rear hub to do this. The sprocket has a fence/flange on both sides. The name of the member of this forum, resident in Belgium, who makes these, has escaped my ageing brain cells but maybe someone else can remember. The followed topics is not working at the moment as otherwise I could track back to when I arranged the purchase of my new sprocket. In a very odd event, the first one that arrived, had bullet damage on it with holes punched right through the packaging and scars on the sprocket. Not what you expect in Europe, so I went and collected the second one from the member's house in Belgium.

PS My brain has just coughed up that the first name of the member who makes the lightweight steel sprockets is Fabian.
