Thanks all. Sure sign that I'm getting old, when Wongstar calls me Mister.
Wonder if young Brett gets called Mr. too

I use Assos as well, so it's not chafing, just the sit bones hurt. My physio told me I have a small ass (he wasn't flirting or anything

so not much padding there.
Good point about aero, I was actually riding mostly upright, so that's what I have to work on.
