Saddle issues

[pll]

I will float two more hypotheses, which I did not see in the thread:

Hyp. 1: I will call this the "phase of the moon" hypothesis and it happened to me in the past. Each month, for a couple of days, my saddle would cause me all kind of grief. I suspect I was just more sensitive during said days... Unexpectedly, the lasting cure thus far was a new wheelset and plusher tires (Conti GP 4000 S, with 320 tpi).

Hyp 2: your weight loss may require raising the saddle just a smidgen to compensate for the loss of 'padding', so to speak. You might be sliding around a little more than before.
