| I went the renthal alloy back sprocket way last C&S swap. It lasted 2000kms and a track day then was goosed.
Goosed, like it had busted off teeth and the rest worn to a point! The chain was aligned properly too and the sprocket was the correct fitment for a 520 x-type chain. Chain doesn't have any tight spot in it and is still on the bike. Front sprocket not worn at all.
It might have been a duff cast but I'm back on steel back sprockets now, stuff the weight saving.
