Zombie thread, I know.
Was just thinking about this thread discussion as I was out riding my EL OS Ryffranck that I recently built up.
Can confirm that this particular example, at least, is far from being unduly flexy under my weight (a bit over 250lbs). Subjective judgment, but I'm actually fairly particular about this.
With the combination of OS tubes configured in the 'Freuler' style (dropped TT, HT and ST extensions), short, highly ovalized OS chainstays, substantial chainstay bridge, etc., the bike is not unduly flexy even when climbing in a tallish gear. It's quite comfortable/smooth, but definitely fast and shows no sign of BB swaying like a pendulum under climbing loads. And that opinion is based on the experience of a rider who has sold more than one very nice bike due to intolerable/excessive frame flex...
