If you're bike has a standard quick release like the one shown below, you'll only need to use the skewer we provide with the trainer.
If your mountain or cyclocross bike has a 12mm rear thru axle (below), you'll need a Traxle thru-axle to safely use your bike on a Kinetic trainer.
Remove your rear wheel skewer to identify which type of quick release you have. If you do need a Kinetic Traxle, please refer to our model guide to find your bike model. If it's not listed, fill out the contact form and we'll get it figured out for you.
