Lab tested: We pressure-mapped 15 pairs of bib shorts to see how much difference they can make

Having pulled together our guide to the best cargo bib shorts, as well as having a hand in our even bigger overarching guide to the best cycling shorts, I am always at pains to point out that they are a very personal item. I stop short of recommending one chamois specifically over another as even among my colleagues in the small Cyclingnews tech team, there is a noticeable variety between what we each like to ride. 

This, though, is quite hard to quantify. It might feel right, but I want to find out how much difference shorts actually make.
