I just bought a brand new chain/sprocket kit in March. I went with a 520 conversion, with a aluminum rear sprocket. I lube my chain fairly regularly and it's adjusted correctly but it's worn badly. So I need a STEEL rear sprocket. All the places I've looked only have aluminum conversion sprockets.

 

what brand sprockets did you buy?

 

Vortex I believe.

 

I've heard good n bad about their rear sprockets. I just installed a set of Driven sprockets -1/+2 steel front n alum rear.

 

Hope you have better luck than me.

 

me too lol

 

I have a vortex rear aluminum on mine and have about 12,000 miles on it with very little wear. Its the 530 though.
