+1 to botto, I've had my performance bike rollers for three seasons and treat them like crud. They are still great and run smooth.

+1 to kudude on the towel, I can do VO2 interval repeats with a towel.

Start riding them in a doorway, with your bike positioned your shoulder is just behind the frame (so if you frantically reach out for the door frame, you can get it with your elbow area). Keep your rpms up and don't look at the floor. You will be able to watch TV while on them, just be careful if you are watching a bike race--you may try to lean into a turn and end up on the floor.

Glad you are going with the performance rollers.
