AndyMark is currently out of stock of the 6 inch Mecanum wheels with steel side plates. We will not get replacement parts for those wheels until June. We are sorry for this inconvenience.
However, we do have a new, version of this same wheel. This new version has an aluminum body and 15 rollers. These wheels will be available by April 12th, and can be hand-carried to the FIRST Championships for spare parts as needed.
These wheels can be purchased in a set of 4, or individually.
