This is the RW pro scooter wheel set from the brand Nitro Circus. Having a hollow core that is made of aluminum, this wheel has a very sturdy and light construction, leaving you no excuse to stay on the ground. The high-rebound rubber makes this a very responsive wheel that is a joy to ride. Moreover the durometer of 86A attests to the wheel's grip and smoothness.
Notice: Make sure to pick a wheel that has a diameter and hub width that will fit on your deck and fork.
These are pro rider Ryan Williams's signature wheels.
