Sugino also makes rings from 5000 series aluminum, softer than 6061 & perhaps not heat treatable.
The original rings on my Atlantis (stock Sugino triple) went around 25,000 miles but were noisy for at least a few thousand before that. The 24 tooth is steel & still in good shape. The 5000 series Suginos go maybe 10,000 to 15,000 miles, tops. That's in So Cal which is pretty easy on drive trains. In the future I'll pay more attention to the alloy. It likely pays off in longer life. Probably try a Surly ring for the outer next time. dougP On Saturday, May 25, 2013 11:43:39 AM UTC-7, Mike Schiller wrote: > > Sugino rings are 6061 aluminum and wear pretty fast.
