The KH Adjustable is only available in 25.4 and 27.2 mm. The new QX RGB unis require 31.6 mm.
I know that a few years ago, some riders used the bottom parts of Thomson Elite seat posts with the top part of the KH as the Thomson is one-piece and offered more colors. The Thomson Elite would be available in 31.6 mm. Are the current versions still compatible to the KH top part?
And as they are pretty expensive: are there other seat posts known that are compatible? (The Sixpack Menace would be pretty cool as it is affordable and comes in different colors.)
