I ordered at a local hardware store so far, but there is a price difference of 150 yen or more and purchased here. The product is made exactly the same as NTN so it does not matter at all. I am somewhat satisfied with saving the labor of going to buy. In future, I will buy other bearings here.
The bearings of the wheel of the unicycle sold at home centers were weak, and the wheels that had been bought remained like a mountain. Therefore, we used to replace the bearings of this size, but even though the use conditions are bad, the durability is preeminent · the force to press the unicycle has also become light. I did not go to buy alternate wheels any more, which also reduced costs.
