<p><font color="00ff66" size="2" face="Arial, Helvetica, sans-serif">- The fiberglass-infused nylon hubs are designed with a ring of captive holes for locking the tire in place.<br />
- Tire tread composed of Shore A20 polyurethane makes these the highest traction wheels you can buy.<br />
- The wheel is designed to envelop a 16mm gearbox. Perfect where length is a concern. (Two Gold Spark motors with these wheels will fit into the 10cm width limit of minisumo events.)<br />
- An extra-long setscrew allows you to easily tighten the wheels onto a 3mm motor shaft.<br />
- Setscrew is accessed through tire. (0.050" hex wrench needed)</font></p>
