Just bought new bike with disc brakes. If I buy an upgrade wheelset do brake discs (rotors) come with? Or do you have to buy them separately?

  • Given you've just bought the bike, leave upgrades alone for a while. Get some mileage on the bike before you spend more money on it.

  • Just transfer your old rotors to the new wheel. All you'll need is an allen key and some thread lock.

Normally the rotors will be separate. Also, there are two kinds of rotor mounts: 6-bolt and centerlock. You can get an adapter to put a 6-bolt rotor on a centerlock hub (I don't think you can go the other way), so it's something to be aware of.
