I just read in my new Posies catalog something scary if its indeed true.
" Do not use tube axles with a split wishbone or hairpin raduis rods. You will break something and it won't be pretty."
This is written on page 8 as a "Posies do's don'ts and HOT tips.

Has anyone ever heard or expirienced this ? It goes on to say that tubes are too stiff and won't flex.
Whats all your thoughts on this?
