I am a bit confused about the differences between threaded and threadless setups.
I purchased a Windsor The Hour with a threaded fork setup. The Cannondale that I have is also a threaded setup, both using the same size quill stems. I have had a 1" threadless setup (Kilo) and now a 1 1/8" (Madison).
I need to purchase a new headset for the Windsor as I am painting the bike, and I would like to switch to Threadless if I can. Here is where I get confused...
Is there a steer tube size difference between 1" and 1 1/8"? Is the headset setup dependent on the frame? everybody talks about swapping Kilo setups to threaded, but I am just having the hardest time wrapping my head around this issue.
