Extended steel seat post is 30% thicker wall tube, than the standard post.. I would suspect the lower section of the
Telescopic post would be using similar tube.
the tube can be further stiffened by putting a tube of aluminum,
or carbon composite for hi tech fans,
inside the steel seat post , and extending up, as far as the top post needs to come down,.. before they meet.
Carradice Bagman mounts on the back of the seat rails, and has an under bag support , for their big saddle bags
and other stuff.. you may tie on..
I got a trailer the Carry freedom city and the brommy team well .
the trailer can carry the folded up bike on top,
and you could run fast to catch trains in that configuration, towing the trailer by its handle.
then when aboard , the trailer folds flat and will stow in a narrow space.
