Kinetic provides this skewer with every new trainer. Extra skewers may be purchased here.
NOTE: We strongly recommend replacing your bicycle's stock skewer with this skewer we've provide with the trainer. We also recommend that you use the stock cone cup already installed on your kinetic trainer. You'll save wear and tear on your own skewer and be assured of a solid attachment for your bike.
This video shows you how to remove your existing skewer and replace it with the Kinetic Skewer provided with your trainer.
