Re: Urethane Wheels Run off Cim Motor

There's a lot more that goes into whether or not a wheel is good for frisbee shooting than "does it use polyurethane"? Polyurethane varies widely in durometer (hardness), thickness, etc. The blue McMaster polyurethane wheels used by many teams this year have a very thick polyurethane layer (seemingly over an inch of polyurethane) bonded to a metal hub / core. Many wheels (Colsons I believe) have a much thinner polyurethane tread molded over a plastic core. Your mileage may vary.

While Gregor's suggestion was somewhat snide, if you do not have the machining capability to make a simple press-fit hub, these wheels really aren't the best option for your team. Investing in several of the Blue Banebots rubber "poverty" wheels would probably be more beneficial. Do note that despite being the same durometer, the Banebots wheels have drastically different wear characteristics than the McMaster wheels, and they need to be changed out over time.
