FUBAR; Is it me?
It was more than just a bearing.
When I went to pull my cranks to replace the bb bearings, I noticed the lockring was hanging loose. Only problem is my bb doesn't have a lockring. The flange had sheared off the cup, leaving the remainder flush with the shell.
Removed the other cup, pulled the spindle, and found the drive side cartridge bearing had completely disintegrated. Yet there was no signs of rust or corrosion?
A trip to the hardware store netted me nothing to remove the now flange-less cup.
My solution; carefully applied violent force. I hammered an old bb tool into the spline-less cup and was able to unscrew the it.
So what gives? How is it that a man who shops in the boy's department keeps destroying cranks and bottom brackets?
Fortunately for me, I seem to always have good luck when it comes to hunting down cranks on ebay. Found a XT Hollowtech II set and bottom bracket for $100. I had a set of those before; loved the stiffness, but felt the bb bearing wore too quickly, but maybe with the precision machining of the Phil Wood EBB insert, they'll last longer. One thing I'm pretty sure of, no matter what the bearing life is, I'm pretty certain they won't implode on me.
