Having ridden the last 2 days of Cycle NC with no neck rest [actually my mounting failed some place on ride day6 of 7 days]. I decided to have the most comfortable rest I used covered with vinyl , with just a bit of padding beneath. I’m to pick it up on Monday. I plan to anchor the bottom CF leaf spring with a screw and then use mounting tape along the length of the spring and the seat-back.
Issue with the setup to the right: The foam was being damaged by my helmet. The vinyl covering will resolve that.
