Thread dredge to post this weird one. My Mavic a119 rims have worn either side of the central wear indicator groove leaving a fairly sharp ridge immediately either side of it. Don't think it's a structural problem but obviously makes the indicator groove a bit pointless. Glad I've got an Iwanson guage that shows them at just over 1mm at the thinnest point so probably due a replacement sometime soon.
