Wheel, Colson, 4"OD x 1.5"W (MK4/4c/4i/4n)

Regular price $18.00

New for later summer 2023, this wheel combines the competition-proven robustness of the Colson Performa Wheel with a custom hub for seamless integration into the MK4 and MK4i Swerve Modules. The result is a setup that provides extended wear life and a simplified replacement process.

Colson Performa Wheels have been used extensively in BattleBots and FIRST Robotics Competitions, including at the championship level. The durable co-injection molded construction of a thermoplastic elastomer tread permanently bonded to a polyolefin core helps ensure the wheel can withstand the rigors of robot competitions, while being friendlier to non-carpeted surfaces.

The unique hub design in conjunction with the custom Colson Wheel eliminates the additional tolerance stack-up introduced by the molded wheel at the hub/wheel interface. This integration results in a hard screw joint robustly clamping against the aluminum hub while accurately securing the wheel.


To change the swerve module from a Billet Wheel to Colson Wheel setup, select the Wheel Kit, which includes:

  • 1 Wheel
  • 1 Hub
  • 3 10-32 x 1 Cap Screws

Including the optional Quick-Change Kit adds the 45T Bevel Gear so you can have a ready-to-install wheel to quickly replace the tread on the robot.

The Wheel Only option does not include the hub, screws, and bevel gear. It is for replacing the Colson Wheel from an existing Wheel Kit. 

Wheel

  • 0.55 pounds (wheel with hub + three screws for attaching the bevel gear)
  • 0.73 pounds (wheel with hub + three screws for attaching the bevel gear + bevel gear)
