Let me be a little more specific, I am a total n00b to bikes. I have no idea what a rotor is, but I do know that there is a red knob on the ProMax caliber. It moves to both sides, front and backwards and has a sticker on it, basically stating 'DON'T **** WITH ME' and towards the wheel, there is two levers, small, one is blue and the other black. They both click.
I do believe the rotor is 'true' due to I took it in to Aaron's Bicycle Repair and they did a full tune-up on it.
