Maintenance, Mechanics, & Tools / Re: Lower headset gap?
« on: May 16, 2024, 07:13:19 AM »
There are 2 different headset bearing designs. One with 45 degree angle and the other being 36 degree angle/chamber. One really doesn't want to mix and match the different angle bearing to different fork/centering rings. With the above stated as one possible problem, gaps are common even when the fork/centering ring and the bearing have the same angles.
(Tolerance stack up.) Different bearing manufacturers can machine in larger or smaller OD chambers that cause the bearing to sit higher of lower on the fork/centering ring. The same machining tolerances can happen with the centering ring.
Almost all of my recent bike builds have a 1-2mm gap.
