Potomac wasn't talking about who wears #1 at the Dauphine, he was talking about who, from Bora, should get to wear #n1 in the Tour. As in the number in whatever set of numbers Bora is assigned that ends in 1...
Each team will have a rider wearing the #n1 dossard.
I don't think CyclistAbi gets the numbering scheme at all. Or maybe she is just being obtuse.
@Potomac was saying a lot of things, in the team thread too, i just reminded everybody on why Maxim is wearing 1 at this Dauphiné edition. As for the rest of debate, started by others, guys likely you are confusing it with young rider classification, or something. All in all the Tour is just around the corner and best to wait and see, on how team numbering schemes will roll. And if any further discussion, beyond what is expected, will be the result.
