Usage:

The R170 wheels can be raced without any additional preparation, but for the best performance please follow these steps.

  • It is important to prepare the wheels for the proper lubrication. Each wheel bore should be polished resulting in a slippery smooth surface. As an example, do not use graphite to polish if you are going to use oil as your lubrication.
  • The hub (inside and out) along with the inner edge of the wheels should be polished to a slippery smooth finish
  • If you are not sure how to prepare a set of wheels consider having Derby Evolution prepare your wheels with the Revolution Race Prep Process

These wheels are legal for:

  • Most Cub Scout races
  • PWDRacing Pure Stock Division
  • Some other league races

Please check your rules to make sure these wheels are legal for your race!
