I noticed a bit of a shimmy under hard braking.
The rear tire has just been replaced. The front has about
1000mi left on it and I thought maybe they had added some air
to the front when they changed the back. So I stopped to let
out about 5psi from the front. I noticed a piece of metal
sticking out of the hub. I could see the ball bearings inside the hub!
I limped to my local bike shop. New wheel bearings/ no more shimmy.
The old bearings came out in about 8 pieces!
And I had been doing my usual 100mph bomb run every day to school (26mi).
My bike has 33k mi. These were the original wheel bearings.
This is why I don't gamble. All my luck is used on the bike.
Check your wheel bearings.
