B&M Wheels

What are the wheels on a B&M rollercoaster made of? If you need specifics, a B&M Speed Style coaster.

Even more specifically: Raging Bull

Anyone know/can point me to a topic?

Polyurethane or somethingamajig.

My understanding is many recent coasters use the Hylene eurethene compound from DuPont. But I do believe that the compounds they use vary significantly depending on the speeds, climate etc. I'm sure everyone knows of the fiasco Cedar Point went through with on Millennium Force tryng to find the most suitable compound for their wheels.

So what if the best coaster in Australia is a second hand Arrow?
