[strictly]

Thanks for the reply. I haven't actually bought the rings yet, presumably if they were "85mm" instead of 84mm, they would have no or 1mm less end gap than "84mm" rings?

I was searching for mahle rings, but they don't seem to make them, in any case a lot of the different rings some specify 84mm and some say 85mm, so I thought I would ask the question if it matterered, as long as the ring end gap is correct, and the thickness is correct (1.5mm/2mm/4mm)
