I've also noticed that myself and have wondered about it. I'm not sure of GP's original design intention but my guess is that the consistency comes from the fact that the Rivendell mixtes are the only lugged mixtes in production, and thus their lugs are the only ones available. The upper head lug, which would be mixte-specific, probably is only made in one set of angles, so increasing the HTA would correspondingly reduce standover height. This also probably explains why on smaller sizes the middle set of stays don't form a straight line with the top tube. The cost to try a new set of angles or have size-specific geometry would thus be high (new lug molds) and probably leads to a "if it ain't broke, don't fix it" approach, at least with these models. You don't hear a lot of customers complaining about the handling of their cheviots.
Do the lugless Riv step throughs (Clem L and the various Rosco mixtes) have different head angles? -- You received this message because you are subscribed to the Google Groups "RBW Owners Bunch" group.
