If the skewer on your bike will mate with the cups on the trainer, then feel free to use it. I would expect that it'll get scratched up, but if you don't care how it looks it isn't a problem. Many high-end skewers have a shape that won't mate with the cups on the trainer, so Kurt includes a cheap skewer with the trainer.
