My fingers got numb after PBP for a week or two in 2015, and I had slight similar symptoms after TCR the next year, but after that I've done even longer rides without problems. The fit is pretty much the same still. I do change the hand positions more often now and generally having my hands and core more used to the long rides must have made a difference, even though I had been riding a few hour rides for years before any of this. Just trying to harden the fuck up is probably not the right answer but anyway.
