Wheel axle:
Are there wheel axles included in your pegs package? If so, you use these for mounting your pegs onto your stunt scooter. Should they not be included, can they be bought separately as well.

The length of your wheel axles should fit the stunt scooter. Keep in mind that there is a difference between the length of your front wheels and back wheels. The wheel axles on the back wheel are usually longer than the ones on the front wheel.
