See, when we talk about chainstays we should be describing the physical object, like the down tube, or seat stay. When talking about Geometry numbers, which are mostly virtual measurements, (think reach, stack, front centre, seat angle etc.) That's when we should be saying rear centre. Long chainstays for me is a misnomer, as the physical object is not always correlated to the axle-bb measurement. I don't get why we can't agree as a community to use these terms, I mean it's not like anyone has ever gotten reach mixed up with the top tube length?
