Nick! first off the bike is looking good! second..looking at that pic of the finished bike and judging off the handle bars assuming the are 1" i'd say that thing is close to 1 3/4" hard to tell but thats what it looks like to me. i'd think youd be okay cause the tire doesnt go directly upward it more pivots on the rockers and would think not that much room is needed? As for the rake and trail i always used the fake trail as thats the way i learned it coming up...Did you find any rockers to borrow??
