Sanko Silent Wheel Flat 25 Used for about 2 months and cleaned. A water bottle purchased at the same time will be included as a bonus (the metal part and the plastic part of the lock have been chewed, but there is no problem with use). Suitable for degus, chipmunks, young hedgehogs, rats, etc. ● This is a very quiet wheel that uses a large-diameter bearing system. ● Compared to the manufacturer's conventional products, the shaft does not hit the back, and the depth is wider, and the feet are flat. ● The shaft cap does not protrude inside the wheel, so it is no longer chewed. ● The wheel body's wobble is reduced, and it is a silent design that maintains smoother and more stable rotation. ● The bearing part and the wheel can be attached and detached with one touch, making maintenance easy. ● The guide rollers have been removed, reducing friction noise. ● A resin plate has been added to the back of the bearing part to reduce the burden on the cage wire. ● Compatible with cages with wire diameters up to 4 mm.
