you have no headset pre-load adjustment with that, at minimum in addition to all the spacers and stem you need a compression top cap from a carbon fork spec. as a star nut prevents re tightening the quill bolt at the bottom of that piece, so you need the removability of the compression expanding top cap
for the headset adjustment.
BBB part # BHP20 is a quill based stem raiser, its inside the steerer.
at the top of the bolt that pulls up the wedge,
the bolt is made to be internally threaded, inside the hex socket,
so there is a threadless headset adjustment,
thru the cap on top of the whole stack
they supply a number of shims keyed to a groove in the quill ,for the threadless stem to grip.
In the US bike Mine has the BBB import distributorship.. NL company Taiwan manufacturing. $25.
