I don’t get it, why do so many people use lay-back posts?
Seems to me lots of people who wouldn’t dream of buying a frame with a ‘relaxed’ 71 deg seat tube angle go and buy one instead with a 73/4 deg angle - but then they fit a lay-back post so that their saddle position relative to the pedals is the same as it would have been with a 71 deg frame.
I know some of them might say a straight post would make their riding position too short, but then doesn’t that just mean they should have chosen a longer frame?
Surely you should get the right length of frame and only adjust lay-back/seat tube angle in relation to how powerful/active a pedalling position you want to have - 74 deg and a straight post being powerful/active, while lay-back or a 70/71 deg seat tube angle (which are equivalent) both give you a less powerful but more relaxed pedalling posture?
Or is this yet another of my many blind spots?
