Did some searching, but came up mostly dry. I see that Supersprox is apparently working on a replacement set which is good news as their products have a really good rating but so far there is nothing listed on their website as being available. Anyone have any recommendations for aftermarket replacement sprockets front and rear in the stock sizes and using 525 sized chain? I am sure a chain thread is not much different than an oil thread, but are there any recommendations for a really good, long lasting O or X-ring chain? Thanks for the help. A friend and I are both at the point where chain and sprockets are going to need to be replaced and I figured I should look here for some advice.
