We chose to use the 100mm Boa Constrictors in our builds not only because we love the cushy feel and solid grip of Boa's 76a duro urethane formula, we also love the extremely high resistance to chunking. 

With a 65mm contact patch, these wheels grip the street like no other whether carving at a chill pace, tearing through the streets at maximum speed, or ripping down a hill. The standard Kegel style hole pattern ensures compatibility with a number of drive systems available to the DIY community for your next electric skateboard build and ships as part of our complete boards and Defiant's gear drive system. 

Includes one set of four wheels. Bearings not included.
