I know nothing about threadless headsets. What's a decent brand to get. Obviously Chris King will be mentioned, but this is a modest build-up with 9 speed 105 components. I only paid $100 for the NOS frame and fork.
What type of labor charge is reasonable to cut the steerer tube and install the headset?
Can I do this myself or this something I should leave to the shop? If it is not difficult what tools do I need?
