Im picking up my 2011 36 1.5 tapered Float for my BottleRocket i have a question on the headset i am going to run a chris king it looks like i might have to buy 2 headsets the Devolution for the top and a 1.5 no thread set for the bottom?. since the head tube on the BR is 1.5 all the way through? or is there another Chris king headset that will work with just one? This is my first bike i have built up so i am not sure?
