These Compliant Stars have a 35A durometer, but are available in colors other than green.

They are offered for a limited time each year at the beginning of the FRC season. If the color you want is currently out of stock, it will be available again around December.

  The greatest grippy wheels for competition robots are available in small batches of your favorite colors. All wheels, regardless of color and diameter, have a durometer of 35A and use white hubs to differentiate them as custom. This is equivalent to the typically green wheels. All other properties are the same as normal such as expansion rates and maximum speeds.

  Compliant Stars are the perfect thing for intake mechanisms. The soft material gives way to allow rigid objects to be manipulated easily. A line of multiple stars on a driven hex shaft creates a very effective roller that ignores variations in the objects being driven. The multiple-spoke design allows the star to act as a brush, creating more surface area to interact with and grab objects. This makes for high-performance intakes and internal conveyors. A shaft collar may be used to make absolutely sure the wheels stay clear of other mechanisms or maintain consistent spacing. Molded into the star are several guidelines. Cut the star at the lines (or elsewhere) to create more compact mechanisms.
