Hah thought this was the CX thread for some reason.
But my point kinda still half stands. There were / are Lyriks and long travel Fox forks in 1 1/8th. If money is no object Lefty doesn't care what your headtube is.
I suspect Alkali is wondering if you frame is even rated for something long travel.
Not when there are still 1 1/8th canti and disc forks available
But where is the fun in that?
Edit durrr this aint the CX thread.
