    Caged ball bearings vs loose on rear hubs

    My XT M775r rear hub has caged ball bearings on the brake side and loose balls on the drive side. I experimented and found that a caged set can work on the drive side. Why doesn't Shimano do this? I think they are all 3/16 balls.

    I like my balls loose. Cages, I believe, are only there to simplify the production line on which the hubs are made. Imagine paying someone to stick in tiny balls one at a time versus sticking in a cage and being done w/it.

    Yeah, cages are just for ease of assembly, and to ensure that you put the right number of balls in.

    Except that one needs to put in more balls without the cage.I think I get what you're saying though. One doesn't want assembly line workers counting out loose balls. There would be too much opportunity for error.

    My balls are caged up almost all day so I lose balls sometime. I also don't mind when they are lubed and handled.

    Probably has to do with the added torque of the brake side. I prefer caged myself because I'm lazy and born with good looks; Many prefer loose because if adjusted properly they'll last forever.
