Zana and Dunbar are talented climbers. Plapp and Schmid have signed for them as well.I don't think Jayco has a good enough team for a Tour winning challenge.
Yates, Matthews, Harper and Hamilton that's pretty much it, the rest are rouleurs.
It's of course not a Jumbo/UAE level team but it's getting stronger (although I think not all of these riders would ride the Tour supporting Roglic). They also have very good equipment and performance coaches.
Not the first option on the table for Rogla but I wouldn't rule them out considering the new funds coming from AlUla.
