These are the same wheels sold with the Trekker Chassis. The wheels are 3.5" in diameter and about 7/8" thick. Two wheels are included and are modified to fit a splined servo shaft such as the Hitec standard servos. It includes 2 long screws for mounting the wheels on the servo shaft.
These ball casters make a good third wheel for 3 wheeled robots, or you can use 2 for more balance.
These wheels are larger drive wheels allowing the trekker to drive faster and add to the Trekker's appearance.
