You gotta think that even the pro riders have moisture problems during a long race, day in and day out. Everything we read about bike performance is about being aerodynamic, power to weight, power transfer. But not especially about the heat and how it affects the rider.
It's not about the ointment on the skin. Its about how to transfer moisture from the skin. I think the bike seat and the entire bib needs to be redesigned. Its about active and passive air flow and materials science. Maybe a year ago, I wrote to Assos, and I got a short response that they're working on it.
