Default Re: aluminum sprockets

Aluminum alloy will definitely wear faster- so it's a matter of how often you want to buy another sprocket. While racing road cycling, I found that a road chainring like Campagnolo might last a few yeras, depending on how much you kept it clean and the conditions you rode in.

A motor and bigger chain would probably wear alloy quickly, but I think I've seen some advertised that are alloy with a steel chainring point of contact- that should last as long as entirely steel, if you don't bend it up somehow.
