It was Gigante that did the damage, it seemed like ELB, Marlen and most of the others were happy to let Smulders hang out there. Not sure what Gigante expected of upping the pace like that unless she was very worried about losing time on the descent (not unreasonable for her) but she had a margin of nearly 2 minutes down to 4th.
Lippert's post-race interview revealed that Reusser has been ill, which possibly explains yesterday and might give a reason why Gigante might have tried something to see if she could jump up a spot on the GC, but it was a very odd one because it was far too late for her to reasonably gain the time she needed especially as Reusser is a better descender than her.
Also it's odd that van der Breggen persisted when she knew Lippert was in her wheel, it should have been patently obvious that Liane wasn't going to contribute when they escaped so close to the finish, and for her part it looked like van der Breggen didn't even ask or consider asking her to, yet Anna needed 30 seconds plus the time bonuses to get past Niedermaier on the GC, I can imagine that was feasible from the first move she made but not from the second, yet she persisted, and all she ended up doing was providing Lippert with a top drawer leadout.
Lippert is turning into a sort of female Julien Alaphilippe (peak era); she will be just about the fastest of a climbers' group left over (unless one of the bulldozers like Kopecky who have the size and build of rouleuses but climb at a much higher level than that make it) and win sprints in stages like this, and she will always just about be viable as a GC threat pre-race, but doesn't seem to be reliable enough day by day to contest the GC outright at these high mountain races. But then, the same was true of ELB for the first decade or so of her career, always having a bad day at the Giro and performing with results below her capabilities for years as a result. And the ELB of back then couldn't salvage the race with stage wins the way Lippert has unless she got a solo escape either. Obviously ELB is a far, far more complete rider nowadays than she was back then, and has got past that weakness, maybe Liane can one day too.
