That question does make sense; though specialization is much less in the women's péloton, the number who truly compete over ALL terrains are limited (Anna VDB, ELB and Claudia have no sprint, Lizzie and Emma J are good on shorter climbs (Emma J has historically been better on longer ones than Lizzie has but will get dropped in a long sustained climb) but less so in TTs, even Marianne Vos has a weakness against the clock), and while most people have at least a balance of skills, there are still some specialists - Cauz and Abbott are pure climbers, Villumsen's a pure TTer - but there's a lot more all-rounders, biased in various directions. Most who are good climbers over longer stuff are also good in the punchy stuff unlike them (ELB, Anna VDB, Niewiadoma, PFP, Stevens, Moolman). Most sprinters are at least slightly durable, whether it be at getting over small hills and rolling terrain (Lepistö, Bronzini), classics stuff (d'Hoore) or pure echelon power (Wild); but a lot of people who aren't pure sprinters can mix it up well in them - take Majerus, Brand, Cecchini, Brennauer as examples. I see Jip as being somewhere in that kind of area at the moment; she's too versatile to be a pure sprinter (she seems to have a fairly good knack of knowing moves to try to follow, and she adapted better to the Emakumeen Bira than I thought she might although she lost a few minutes in the more sustained climbs on the final day) but most of her best results are on home roads from more reduced sprints. As she gets stronger and a bit more experienced (plus if she gets a team, either Parkhotel developing her or moving to another team, that can offer good placement in the bunch/protection) I can see her being one of those riders that people need to shake because she'll still be able to be there when the bunch only has 20-30 in it.
Anyway, I see you edited your "it's" to "should be" while I was writing that... given all that I've written above, I think we're all now pretty clear that it's Jip van den Bos.
