    I recently adjusted & lubed the wheel hubs on my trailer. I thought they would be standard road, 36
    hole, 100mm spacing front hubs, but they are not. The trailer was manufactured in July, 2000 and the
    hubs have the word "Mount" on them. The spacing is 99mm. Inside there are seven, 3/16" ball bearings
    per side. The balls are held in a cage, like headset bearings.

    In the future, I will probably want to build a set of wheels for the trailer. I prefer using 105 or
    Ultegra hubs, but their 100mm spacing is a really tight fit on the trailer. Any ideas?

    One millimeter difference isn't much. If I recall correctly, the "dropouts" used to hold the wheels
    to the frame of the trailer are made of aluminum, so a few strokes with a file will open the
    clearance enough to easily fit 100mm hubs. The dropouts can be easily unbolted from the frame tubes
    to make it easier to do a workmanlike job.

    You should be aware that friction losses for any well-adjusted hub are very low compared to other
    sources, and that the differences (in friction) between cheap and nice hubs are vanishingly small. I
    am assuming that is the reason you are considering replacing the hubs, so correct me if I am wrong,
    but I wouldn't bother for the trailer.

    Change the locknuts? Remove the washer between cone and locknut? Spread the trailer ends from 99mm
    to 100mm? Shouldn't be hard to find 0.5mm per side.
