Rear Hub Bearing Roar

The last time the bike was on the work stand I was re-lubing the
shifter cables and noticed a "roaring" sound when the rear wheel was
spun up to a pretty good speed.


The noise is more likely freehub or freewheel noise. There are an
inordinate number of 1/8" ball bearings in there and they can make quite
noise when spun up, probably from the cogs resonating or something like
that. The noise never really goes away unless you grease the
freehub/wheel, which is a bad thing. So just lube the freehub/wheel with
some fairly thick oil and it'll be fine.

Cheers,

Scott..

Yeah, the Deore freehub on my touring bike does the same thing. I did
everything I could think of to make sure it was properly lubed, but it still
"roars". I've ridden many thousands of miles on it with no problem.

Only when the wheel is rotating backwards.
