Flamme Rouge. Unless you mean you want to be the lanterne rouge
There's no frame choice in any of the races. For TTs riders get the standard Zwift TT, and for other stages everyone gets the standard Zwift road. It happens automatically. Yes, you do get to choose the wheels
[EDIT]: There's also no power ups.
I'll probably do this stage as well. Anyone know what the fastest wheels are for the TT bike? I have 14 million drops and level 52 so I assume I can access everything.
