Luddite
Got myself a new DID gold chain as it's needing a new (shiny) one, but really struggling with the rear sprocket. Been on to design corse and can't decide between the AEM factory set up or the CNC Racing setup. I love the look of both. But how many miles will I get out of the aluminium sprockets? I have looked at Renthal (tried and tested on previous bikes) and love their products but fancy something a little more special.
Any suggestions or experience of these products?
