yoyo shields???

It was really hard to take off…

would you recommend that I leave the bearing without shields???

some people like them on and off. on they protect against MOST dirt and debree, howevor is a bother taking off every time. no shields on mean dirt and debris can get it with nothing stopping it. however no shields are easier to clean and apply lube and whatnot. some of my bearings are deshielded and they work fine and nothing wrong. plus its really easy to lube and clean. ites your choice

Deshielding gets easier with time. I keep my shields on.

I prefer them on to protect from most dirt.
