FWIW...femur length dictating saddle setback is baloney. I am not against a lot of setback, but femur length is not a criteria.
Look...we all have to sit back and laugh about fit...especially on the internet. It is a bit of a joke, but some issues are glaring.
There is no ideal fit for any rider. Fit depends on flexibility as much as body proportions for example.
If you like your fit, then don't change.
All too true. Plus, I don't think anyone was trying to "fit" rbart. Just some comments that, in the absence of observation or details, at first glance those numbers seemed kind of off.
