This black plastic wheel is press-fit onto the S90R output gear shaft, and easy to make a nice drive solution for small robots. The wheels have silicone tires and measure 60 mm (2.36″) in diameter. Two additional mounting holes for 3-40 screws make it possible to use the wheel with several of mounting hubs.
