Sick Looking sprocket

By Christopher from Aurora, CO

Pros: Looks awesome, reasonably priced, super light

Cons: only con is life span as opposed to steel

I cant really say anything bad about this sprocket, it looks pretty sick and is super light weight. The only con which i wouldnt really say is a con is that i probably put 10-15k miles in a season which is enough to wear it out but the only other option is steel sprockets but those weigh more and doesnt look as cool but i would definitly reccomend this sprocket if you dont put as many miles as i do in a season
