I was fitted on the bike already - seat position, height, reach etc - and at the bike shop it all felt great. Of course, I was wearing the extra layer of underwear thinking I might not keep the shorts. Took the underwear off today and within 30 min I have chaffing. The seat itself feels comfortable. My sit bones are nicely supported. There is some pressure on the front, but I'll probably end up switching to cut-outs, but I need to figure out this chafing first.
