The Vortex are the most adjustable $ for $!
The PRO's is that you can do what you want...
The CON's is IF you go all the way down and back... your kick stand will interfere with your shifter.
Now you will have to adjust your kick stand to be lower (Which will cause it to drag when leaned over)...
Soooo, You decide what is BEST for you... Buell Pegs or Adjustable Pegs....
BTW - I have set of Vortex 4-Sale...
