Installing a headset reqires a headset press and a crown race slide punch. If you don't have these tools, have a bike shop do the installation (usually $15-20).
2. Seat the crown race on the carbon bike fork crown. This requires a crown race slide punch. Pound the crown race down until it sits flat on the fork crown.
5. Slide the cup press through the head tube. Install the lower half of the press.
6. Turn the handle on the top of the cup press clockwise while holding the bottom of the press with a wrench. Work slowly and carefully, making sure the cups press evenly into the frame. Be sure to tighten the cups firmly into the frame, but do not over tighten.
7. Remove the cup press.
Tips & Warnings
Some sealed headsets have the bearings pressed into the cups. You may need a special adapter for your cup press to make sure that you don't damage the bearings during installation.
