I just noticed the difference and I'm curious when this occurred. I have a cracked frame serial A0913 (Yellow) with straight chain stays & another in white with the powder coating hiding the serial aside from a barely visible A which has the curved stays and narrower weld beads.
Well after a quick search looks like 95 was the 1st year of the curved stays. Mystery solved!
