Coincidentally I was thinking it's new chain time on Wednesday's ride. I can hear the chain just a bit recently, especially when it's in any gear combo that presents a slight angle. Not bad, just not silent anymore.

Checked my ride data, looks like 1,500 miles since my last chain replacement back in the late fall/early winter.

Seems a bit early but I do ride gravel and gritty chip seal and rural routes about half the time, so maybe 1,500 miles is reasonable for that mix.

My '92 bike has an older but still replaceable Shimano Hyperglide cassette, so I'm not too worried about that. But the triple chain ring is an Exage aluminum 30/40/50. Probably harder to find and more expensive. Better to replace the chain earlier.
