Product review (5 stars): Perfect, tight fit so wheel won't fall off
These are perfect. Wheels are the same as my previous ones it is the roller stud that it comes with that makes the difference in the wheels not falling off  - clips on tight with the new stud - which it appears you can order separately as well if the stud is all you need.  One thing was it seems some of the wheels came with the old clip still inside, it took a lot of force to get it out to insert the new stud that came with these wheels.  Kind of odd and a pain to take that old clip out but this replacement works well.
