Measuring top and bottom gaps
Loosely quoting the product guide for the Bib hanger:
The top gap should be equal to, or slightly less than the bottom gap.
This I am fine with, you want to get the best grip you can on the CCs, and that is the way to do it.
My question is, how do you measure the top gap?
Is it the distance between the teeth? Between the rubber moulding?
