the ball bearings seem to be of really good quality! I would definitely recommend these and the price and quantity is a great deal. I used it for my rear and from wheels of my mountain bike.

In the end, I was the one who placed the order, but a smaller size was delivered because the display showed a different size from the one I initially selected.
