Pololu introduces the Pololu Wheel 90 x 10mm Black (Pair). These black plastic wheels press-fit onto the 3mm D shafts of Pololu's mini metal gearmotors, micro metal gearmotors, and 120:1 mini plastic gearmotor 90-degree 3mm D-shaft output to make a nice drive solution for small robots. The wheels have silicone tires and measure 90 mm (3.54") in diameter. Two additional mounting holes make it possible to use the wheel with Pololu's universal mounting hub for 3mm shafts, 4mm shafts, 5mm shafts, and 6mm shafts. The slots in the six spokes allow additional accessories to be mounted to the wheel (e.g decorations or parts of an encoder system). The left picture below shows the wheel mounted to a 37D mm metal gearmotor with a universal mounting hub for 6mm shafts. The wheels are sold in pairs.
