I recently purchased a Quiver Disc frameset like this
https://www.fyxation.com/products/quiver-disc-frameset
The website states that it requires an IS41 integrated headset, which is what I bought. The fork crown seat OD is 30mm, the same as the inner diameter of the bearing. When I install the split crown race, I am unable to push it any further down than what is shown in the attached photo. As you can see, there is a gap there. Did I buy the wrong headset?
