There are a lot of requests and questions regarding where to purchase contact wheels. As you know there are two types of contact wheels, smooth and serrated. They come in various diameters from 2″ to 14″ with 2″ widths. The most common sizes used are between 6 and 12 inches in diameter.
There are very few suppliers in North America with most being in the USA. Most of the US suppliers are re-selling items from Aliexpress. The other USA suppliers start around $300.00 cdn and prices go up from there.
