This should come as no surprise, but I have the same problem. The issue I'm having is that the PI shorts I've worn for the past 5+ years are now no longer correct. I have no idea what happened but my sit bones are now in front of the widest part of the chamois on these as well! It may be the new saddles (which work GREAT with tri chamois but I need more padding for longer rides). It may be more aggressive positioning. I don't think it's weight loss as I'm not even down to where I was when I started cycling yet. FRUSTRATING!

Now I need new to find new bike shorts! Ugh!

And here I was going to ask for your recommendations and all you've got for me is PI? Crap.
