Just wondering if steel chainrings are rare. It seems all I look for are aluminum.
The reason I ask is because I had replaced the chain on my Norco assuming the old chain was the reason for the tight spot I had in the chain adjustment. Turns out the front chain ring/crank is about 2mm laterally out of true.
While the chainring's teeth are okay, the way the chain wore the valleys between the teeth pushed metal out to one side of about half of the valleys. I cleaned it all up with a small file on the side of the valleys.
Then it got me thinking why not a more durable solution such as a steel chainring on a single chain ring bike? The single rear sprocket is steel, and of course the chain is steel. It made me think of the aluminum sprockets on motorcycles and how much I hated them on non-racing machines.
