What do you mean "only"?Only 4.9% of top1000 riders according to PCS ranking are either Norwegian or Danish so you can already see how much of a limitation it is. And out of these 4.9% some are bound to end up at other teams than Uno-X.
This debate started with people saying Norway and Denmark had to small a population base for the project.
4,9 % is 700 times better than the share of world population, so you are making my point, that it matters what countries are specifically in question
Obviously it is easier to be able to pick riders from all over the world, but saying a Norwegian/Danish squad can't work is far from the truth.
I mean, the top 20 on the list is:
Fuglsang, Asgreen, Mads P., Kragh, Vingegaard, Kristoff, Honore, Foss, Hoelgaard, Tiller, Cort, Halvorsen, Kron, Valgren, Casper P., Leknessund, Moerkoev, Wurtz, Bystroem, Skjelmose.
With another 5-10 Doms to complete it, that would be one of the strongest teams on the WT.
Obviously a team would be hard pressed to sign them all, but even signing half of them, would still be plenty good to be competitive on the WT, and one should not discount that many of these riders would love riding for a "local" team, if the money is adequate and the sporting prospects fair.
