Had this problem particularly on my last 400s and 600s. My bib shorts have a seam at the junction between the shorts and shoulder straps bit, and this over the distance seems to effect a painful rub.
Does anyone have any hot tips on how to control this? Some ideas so far are:
A. Investing in some boutique pair of super shorts or even an all-in-one which don't have a seam in this part of the body, to use in proper big rides - which isn't preferred because I'm not in a tip top financial position right now.
B. Hope that chammy cream or bodyglide (which I used to use in long distance rowing) might resolve the problem
C. Sew something on the inside of a pair of shorts (
).
