Chirp Wheel - What’s the Difference between a Chirp Wheel and a Foam Roller?

There are two main differences - width and pressure.

1. All Chirp Wheels are 5" wide. This width is perfect for putting the pressure where it is needed along the spine and between the shoulder blades. A foam roller just steamrolls the whole area with no real focus. 

2. Chirp Wheels come in 4 sizes (diameters) -- 12" 10" 6" and 4”. Due to the size change, the area in contact with the muscles at any given point provides a different amount of pressure. Think wearing high heels in the snow vs. actual snowshoes.
