We'll see how it goes with the cassette and any mechanical efficiency issues. If indeed present, I should notice it with the 9t cog on the cassette.
The parts were ordered and should be here soon. The fork is still being polished and plated but should also be done soon. The wheels are finished, however:
The 35mm Schwalbe Kojak's expand to a nice 37mm on the 35mm rims. The size "CX" Tubolight inserts are too small for the 30mm IW rims and will not guaranty the bead stay in place. Apparently, size S is what I should have ordered but diameter specs are not mentioned on the website. Those will be ordered shortly.
Right now I am concerned about the rear brake adapter, which requires modification of the frame. When I have the rear brake adapter, I will mount everything, measure and drill/tap.
