Stem raiser in its simplest form is a tube with a wedge in the bottom..

half way up it flares.. the top inside is the bottom outside diameter.. so, you take the stem out of the fork,

put the riser in then put the stem in the top of the riser.. then replace all the cables to reach the new altitude.


(Prettier, costs more.. Nitto Technomic a stem with a long quill shaft. still going to need new cables though..
