There have been a number of threads about riser options for the ST bikes, and I've just finished the installation of Cycle Cat risers on my ST3.
Here's a few pictures:
My goal in installing the risers was two fold. First, I wanted to change the rotational angle of the clutch and brake levers downward. Second, I wanted to change the angle of the handle bars to take some of the pressure off of the outsides of my hands. Being able to actually rise or lower the bars was of much lower importance.
I can report that the Cycle Cat risers met both of these goals, and are also of immaculate workmanship. Highly recommended.
