Ha ha.. so this still has legs :lol:
basic anatomy of a human being means you cannot get your CofG “behind” the rear axle centre line without tilting the bike upwards to quite a steep angle
This ^ is absolute rubbish!
Do you have really poor flexibility or something Max? (ie. do you find it difficult to touch your toes?).
To get your CoG back far enough, what is needed is decent enough lower back flexibility to get really low hanging back off the bars and trust me, this is possible on a standard mtb wheelbase.
I have no interest in looking at ANY videos or PICs as I can already achieve what you seem to deem impossible.
my BMX chainstays are 14.5″
my hardtails chainstays 16-17″
and there’s only an inch difference between TT lengths.
with my 33″ inseam I truly don’t find it too difficult to get my CoG far enough back.
I’m not sure why you are finding this so difficult to believe.
