The Kinetic Shewer is recommended for use with Kinetic Trainers. It provides the strongest attachment with Kinetic Trainer small cone cups. It also protects your bicycle's stock skewer from wear and tear.
Kinetic strongly recommend replacing your bicycle's stock skewer with this skewer that they have provided 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.
