These can be used in place of skate/skateboard wheels on most dollies. This allows you to use your dolly on any uneven surface. The CW4’s can be used on any pipe with an outer diameter up to 1-5/8inches (44mm).
The diameter each wheel is 58mm (2.28 inches) and a width of 33mm (1.30 inches). Each wheel comes with 2 installed bearings with a 8mm bore (you can use a 5/16” bolt).
The new CW4 feature an updated U-groove that combines a u-groove at the base and continues into a v-groove
This combination will offer better stability on a wide variety of track sizes.
