Exotic Nutrition's Silent Runner Wheel 12" is the most innovative wheel on the market for its safety features and whisper-silent spin. You'll love this wheel's silence, safety, and durability.
Measures: 12" wheel diameter, 3.5" wide track, 4" diameter openings, 13.5" tall on stand.
What is dual ball-bearing technology? Two stainless steel ball-bearings are positioned within the back plate of the wheel, ensuring the wheel glides smooth and silent. The innovative bearings SPIN around the center pin as your pet runs, unlike annoying squeaky wheels on the market that have an axle that the wheel rotates around creating friction and noise.
