Just checked the rods.
They all have H engraved on the top and the cap.
The top of the rod meterial differ'd from
9.3mm = 4wd,
5.9mm - 7.75mm = 2wd rods.
Also wiegh'd them,
Caps wiegh 158 - 167 grams, Rods = 463 - 474 grams, both together in they sets 629 - 633 grams.
But one of the 2wd rod is the same wieght as my Fiecos 4wd rod, for the cap, rod and complete set.
