When I rode Reno to Mendocino (375 miles with 30K climbing or so on gravel and asphalt) I brought a pair of Asso. I have to admit I never wore them. Instead, I opted to wear a very dirty L1 bib that I wore for 8hrs of riding the previous day. Flash that was probably what that smell was....
The guy who wore Asso got a Saddle sore. I was fine. Just some friendly ribbing.
