    ABEC 3 or 5 for wheel bearings and freehub?

    I'm going to be replacing the rear wheel and freehub bearings soon. They have never been the same after I discovered that the drive side cone nut had been loose for awhile and I had number of rides while in this condition.

    Background:

    Back in the spring, I was having creaking noises and one of them was the BB bearings, but even after installing the V2 bearings ('12 Madone), I continued having noises. I later found (on a humble) that the drive side cone nut was loose, but I don't know how long it had been loose. The bearings felt rough, so I repacked with grease and it was ok, but they just were never the same. So, now I plan to just replace all 4 bearings.

    It's my understanding that higher ABEC ratings doesn't necessarily translate to better bearings. I read Enduro's information on this topic and noted the difference between their ABEC 3 and 5 bearings are the 5s have tighter tolerances, different grease, more roundness of the balls, frictionless retainers and some other stuff.

    In the bike world, which bearings are used?

    Would you go with ABEC 5 since they have a better build?

    Thanks...

    'brifter' is a lame word.

    Sure, why not? You're never going to feel the difference but the better quality bearing with better lubrication will last longer.

    Thanks. That is what I was thinking, too. I wanted to check to see what others have done when it comes to wheel bearings. I ordered the 5s.

    All done. No more roughness. The 2 freehub and drive side bearing had a roughness to them; that's was the side that had the loose cone nut. The non drive side bearing was still in good shape.
