Qu-ax Aluminium Seat Post with Gusset.
In my opinion, this is the strongest aluminium seat post on market. Only a few hardcore ride destroyed this seat post.
It seems Qu-ax made a nice seat post: Strong and lightweight with an excellent Price-/Performance ratio!
Aluminium shims (see below) works fine for using this seat post with Kris Holm, Koxx and ONZA unicycles.
